Stores, hospitals, entertainment venues, and other places where the public are together in large numbers, use secret codes to pass information between store employees. These are meant to be a secret as they don’t want to alarm the non-staff members or alert someone (like a thief) to the fact that they have been noticed. Many stores have their own codes – for example WalMart, but there are a number that are nearly universal in application. This is a list of ten secret codes that may prove useful to you in future, or at least dispel any curiosity you may have if you hear them.
The Ten Codes are a list of codes used by law enforcement officers in the United States. They are available on the Internet which would make them seem inappropriate for this list, but a large number of police departments have tried to have them made illegal for distribution, so they deserve a mention. The codes were developed initially in 1937 and were expanded in 1974. The California Police use a variety of extra codes which predated the ten codes. For example, a 187 (one eighty-seven) means homicide. In the ten codes system, a 10-31 means that a crime is in progress, a 10-27-1 means homicide (the 10 is usually not said when it is a three-number sequence), and a 10-00 (ten double-zero) means “officer down – all patrols respond. Wikipedia has a complete list of the police codes here.
In computer support, a variety of codes can be used when referring to a customer. One of these codes has become fairly well known on the internet: PEBKAC (Problem Exists Between Keyboard And Chair) but there are a variety of others that are lesser known. One of these is used when reporting a fault which has been fixed: “The fault was a PICNIC” (problem in chair – not in computer), or “ID 10 T Error” – ID 10 T is, of course, IDIOT. Let us hope that you never see this noted down on your file when a serviceman is fixing your computer.
Time Check (usually taking a similar form to: “Time check: the time is 12:00″) can be a code in stores for a bomb alert. It alerts the staff to follow the bomb procedure, which can be to either try to locate any suspicious packages, or to prepare to get the hell out. If you hear a time check in a store, it is probably a good idea to start moving toward the exit. Surprisingly – and shockingly, the majority of stores that use this code actually expect their staff to search for the bomb – certainly an aspect of the job that the majority of teenaged checkout operators weren’t expecting when they signed up I am sure.
A code 10 in hospitals can refer to a mass casualty or serious threat (such as a bomb alert), but the majority of people experiencing a code 10 will do so for another far more common reason: a “code 10 authorization” is made by a merchant when he needs to call a credit card company to enquire about your card. This means that he is suspicious of you or your card and doesn’t want you to know it while he gets it checked out. When the credit card company hears that they have a code 10, they will ask a series of yes/no questions to the merchant in order to find out what the situation is. This will often result in the merchant keeping your card if they believe it is safe to do so. This type of call often results in a call to law enforcement.
“Doctor Brown” is a code word often used in hospitals to alert security staff to a threat to personnel. If a nurse or doctor is in danger from a violent patient or non-staff member, they can page Doctor Brown to their location and the security staff will rush to their aid. In some hospitals, code silver is used to refer to a person with a weapon, and code gray can mean a violent person without a weapon. Hospitals have a huge array of various codes to describe all manner of situations. They often differ from hospital to hospital and they are usually not internationally recognized.

On a ship, a code oscar means someone has gone overboard. If the ship has to maneuver erratically to handle the situation, it must also send out blasts on the signal so that other ships nearby are aware of the fact that it is about to change its course. It should be noted that ships don’t have an internationally standardized set of PA signals and they can differ from place to place, but this is a fairly commonly used one. Oh – and a code delta can mean that there is a biological hazard – though who knows what that might be on a passenger ship. And finally, Code Alpha often means “medical emergency”.
Code Bravo is the code phrase for a general security alert at airports. Unlike most of the codes on this list, the code is meant to cause alarm – but not through knowing what it means: when this alert is raised, all of the security agents will begin to yell “Code Bravo” in order to frighten the passengers – this is supposed to make it easier for the agents to locate the source of the problem without interference from the general public. For those of you who travel on ships from time to time, you may like to know that Code Bravo means “fire” and it is the most serious alert on a ship – if it burns, you either get off or burn with it. Ships also often use sound signals, such as 7 short and 1 long, meaning “man the lifeboats”.
Inspector Sands (or sometimes Mr Sands), is a code for fire in the United Kingdom. Obviously it would not be appropriate for the service staff of a store to announce a fire publicly, so this code is used to alert the appropriate staff to the danger without upsetting customers. The wording differs from place to place and in the Underground network a recorded “Inspector Sands” warning is automatically triggered by smoke detectors. In some shops you will hear the code used in a phrase such as “Will inspector Sands please report to the men’s changing room” if the fire is in the men’s changing room. It was played on a continuous loop through the underground during the July 7, 2005 bombings, and has been incorrectly described as a code word for a bomb – the frequently used code for a bomb in the Underground is “Mr Gravel” – for example, “Mr Gravel is in the foyer”. Mr Sands (or sometimes Mr Johnson) is also used in theaters in the case of fire. You can listen to a recording of the Underground “Inspector Sands” warning here.
WalMart gets its own item on this list because they have a large number of codes that are store specific. Some of their codes should not worry you – for example a code 10 or a code 20 just means that there has been a dry spill or a wet spill – the biggest danger this poses to you is that you might slip over. A code 300 calls for security and a code orange means there has been a chemical spill. But here are the ones you really need to worry about: Code red means there is a fire in the building – get the hell out if you hear this. Worse still, a code blue means there is a bomb in the building. Exit swiftly but don’t run – in case they think you planted it. A code green means there is a hostage situation and a code white means there is an accident. The one you are most likely to hear is a code c which is simply a call for customer service (usually meaning that more cashiers are needed). And finally – the most famous WalMart code… well, it’s so famous it needs its own item:
Code Adam was invented by Walmart but it is now an internationally recognized alert. It means “missing child”. The code was first coined in 1994 in memory of Adam Walsh, a six-year old, who went missing in a Sears department store in Florida in 1981. Adam was later found murdered. The person making the announcement will state “we have a code Adam,” followed by a description of the missing child. As soon as the alert is heard, security staff will begin to monitor the doors and other exits. If the child is not found within 10 minutes, the police are alerted and a store search begins. Also, if the child is found in the first 10 minutes in the company of an unknown adult, the police must be called and the person detained if it is safe to do so. In 2003, the US Congress passed legislation making a “Code Adam” program compulsory in all federal office buildings. A similar alert is called an AMBER alert, a backronym for “America’s Missing: Broadcasting Emergency Response” but initially named for Amber Hagerman, a 9 year old girl who was abducted and murdered.

Wow, another excellent list! Thank you!
ya
I was reading the wikipedia articles about these codes very recently. Great minds seem to think alike, at least some of the time. One article said that another meaning for "code brown" in a hospital is that a patient has defecated on him/herself.
I'm wondering what the police code for "I have apprehended a clown" is.
that would be a code “BO-20″
That WAS funny. I would have tltoaly come to your kick ass party, except…
Cool list, Love the shirt on #9 lol. I know quite a few people that discribes. Keep on keepin on JFrater. Love this site!
awww so close to being the first comment, great list though i never knew these things, i will watch the computer guy closer next time….
I always wondered what Code-Adam meant. Thanks.
Interesting list. Wonder if the IT guys my husband works with ever use the ones in number 9. I forwarded it to him, so if they haven't yet, they may now!
HAHAHA My boyfriend works in IT I sent this list to him as well. I believe I will be seeing them flutter through support emails all over the office
10-codes vary between police departments.
Thanks for pointing that out, so I didn’t have to. ^^
To support that, the sheriff’s department where I live uses 10-33 instead of 10-00 for officer down, need immediate backup.
In response to astraya's comment, I don't know what article you were reading but defacation is NOT another meaning for a code brown in a hospital. Think logically about that, how would switchboard know, and why would they need to broadcast it to the entire ward/hospital? The patient's nurse is informed by either the patient buzzing the nursing station, or another nurse verbally telling him/her. I'm pretty sure if anyone was referring to a "code brown" as a bowel movement, it would be used humorously, and not as a literal emergency code! In Canada a "Code Brown" is a (often chemical) dangerous/hazardous spill; Something than cannot simply be mopped up by housekeeping
Everyone in my hospital knows what a "Code Brown" is, it is never announced over the public address system, but it is announced with a twisted nose to all at the nurse's station.
By the way, "Nurse Betty" is our hospital ghost, blamed for all sorts of strange happenings.
Really, a hospital ghost? I sure hope you’re not a doctor.
Why? Doctors can believe in ghosts or aliens for all I care once they’re good at their job it doesn’t matter what their personal beliefs are. There are plenty of people that don’t believe in any of those things and are careless in their job.
Thank god, somebody else who has an open mind on the internet! Thank you for restoring my faith in humanity, Ms-binks
hope I made the top ten comments
.
Great list big fan of listverse!!!!
Huh…
I'm not entirely sure why but that picture of the doctor for the 'code brown' made me laugh for what seemed like forever. looking back, it wasn't that funny at all.
when i read the title, i thought of the time my friend was working at Hobby Lobby and told me the code for needing change in the registar and then said 'oops..you're not suppose to know that'
The picture is from the webcomic Dr. McNinja.
wow these are pretty interesting, good to know
NurseBetty: I read it on wikipedia, so it must be true! I'll look for that, and see if I can find it. You make sensible comments there, and I bow to your experience.
http://en.wikipedia.org/wiki/Hospital_emergency_codes#Code_Brown:
Code Brown
Severe weather (Texas Tech University Health Sciences Center)
External Emergency (Australian Standard)
Missing Adult (University of Toledo Medical Center) (University of Cincinnati Medical Center)
Medical Gas Emergency (Carolinas HealthCare System)
Chemical Spill (Ontario Hospital Association)
Any incident of someone defecating (slang among nurses regarding defecation)ie:LLUMC [I searched for this and the top match was Loma Linda University Medical Center, California. Possibly it is nurse-to-nurse and not for general announcement.]
Astraya – are you sure you aren't confusing it with the brown sound?
Now I know just what to yell when I go on my next Wally World terror spree! Sweet!
Astraya: I think it may be code 10-*
10- *
That *****es me off, ignore the periods; 10- .*.
you know what forget it
Dope list. We have a code 10 were I work (supermarket) but instead we use it for shoplifters.
used to work in retail for quiet a few years. code 10 was and is being used as correctly mentioned in the list. perhaps the codes are also being used differentially and have alter interpretations x
I've heard inspector sands before and it scared the hell out of me, good to know!
kind of reminds me of that movie 'Choked'. Nice list by the way.
Is 10-4 part of the 10 codes? What does it mean?
it means "yes" / "ok"
In Denmark “10-4″ (“ti-fire”) means great, superb, awesome etc. and is used “that’s (just) 10-4.” (det er (bare) ti-fire.”
The problem with #6 – that different hospitals have different codes is very real. I was discussing this with a relative who works in different hospitals… she has to keep code cards with her IDs for constant reference. Confusing and potentially life threating.
Jamie, on an admin note: Can you put the authors name up top? like a byline in the newspaper.
(1) may prevent 'JF wrote a terrible list' comments when JF didn't write it.
(2) I like to scroll down to see the author of the list before I start reading.
Tomo: yes, 10-4 means ok, understood
stevenh: it is quite a complex task to put the authors name at the top but I will see what I can do
NurseBetty my wife is a physicians assistant and has joked with me of nurses coming out of a patients room saying "we have a code brown." They don't broadcast it on the PA unless the code brown involves a morbidly obese patient. That even I have heard of it as I have no experience working in the medical field probably means it exists to some point.
Now that’s a fun use, tguohh a bit too permanent to be practical. They do make for interesting tile designs
When I was in Highschool there was a search by cops and drug dogs one day and the office paged the entire school with the message "If anyone has seen the red dictionary would you please return it to the office" It was pretty obvious what that meant to us when we were told we couldn't leave the class room even though the change of periods was coming up. The teacher that I had at the time was severely drugged out at the time and simply said to us "Oh I hope they find that red dictionary soon"
This is an excellent list. Great job as always, jfrater
Thanks matt – I really enjoyed writing this one – I learnt a lot in the research
So, we're not meant to know these, and I think for good reason, yet you're telling them to us?
long time reader, first time poster (haha, i always wanted to say that
). awesome list jfrater. and a shout out to my boy Dr. McNinja at #6!!!! hahaha
Jonesy: thanks for the comment – having studied ninjutsu I had to include dr ninja – I am glad someone appreciated it
Having worked in shops in Belfast for many years I neevr heard the time check one. What I have heard used is:
"Could the plumber come to the basement"
"Mr Smith to security" (dunno what happened if there was a Mr. Smith)
As for the searching thing, that was always fun. Usually ended up in an argument about who looked in the cupboards…
I am a nurse and we use tongue-in-cheek codes all the time. We have to laugh sometimes or go crazy. Here is an article listing some of the more common ones.http://en.wikipedia.org/wiki/Medical_slang. We also call the new crop of interns in July baby docs.
I work in scotland in a supermarket and we have a couple of codes for staff. We have "Mrs White to customer services", it's a non aggressive shoplifter and "Mrs Black" is a violent customer/shoplifter. Anytime you hear those codes over the tannoy system you see all the security guards and the male managers running out the door chasing them, so I'm sure the customers have worked out the codes by now, it aint hard and they aint dumb (well most of them).
I used to work at a YMCA and when a Code Brown was announced it meant that there was a turd in the pool, everyone had to get out and maintenance was needed immediatly so the pool could be sanitized. Seriously.
haha reminds me of Chuck Palahniuk's "choked". good list!
Interesting that you should mention #9. This past weekend there was a series of bomb threats at a local Walmart here where I live. My wife happends to work there and every time the bomb threat was called in they announced a code blue. Everyone in the store immediately evaculated the building. The bomb threat caller did this a total of 8 times before getting caught. She now stands to receive a maximum of ten years in jail and $10,000 fine for each count, totaling 80 years and $80,000. She had just got laid off Walmart, btw.
Hmmm, i'd be more inclined to interview your wife. She has been there for every incident… lol Just kidding..
)
this is such a delicious list
3568!!
5638 i mean
Ok, guys and gals… I am pretty much a perfectionist when it comes to obtaining the absolute correct info on a topic, and it usually doesn't come from wikipedia. This is aimed mostly toward astraya's comment "I read it on wikipedia, so it must be true!" Wikipedia has some terrific info, but that doesn't make it absolutely true since it is an open database that anyone can contribute to… even some of the idiots out there. Wikipedia is not even accepted by most college professors as a reliable source to cite in term and research papers because of this reason.
Also, Chuck P's book is called Choke… not past tense (Choked).
Sorry… not trying to be an *****. Just letting you know.
What about wikileaks?! lol. So true, they want his ass in jail!! lol
BTW, JF… awesome site. I have been visiting List Universe for a while, but just recently started with the comments. Mainly because of the top 10 funny comments list a day or so ago. Great work with the site and keep'em coming, mate.
when i was at a walmart in college a nervous sounding teenage girl employee was requesting help in the toy section. she was not well practiced in the giving of announcements so she said over the loud speaker "i've got a customer by the balls in toys and he needs help".
the entire store erupted in laughter.
My life guard friends have their own codes while on duty. Most of these are hand signals, but some are accompanied by words.
"Reeling in the brown trout" means someone has pooed in the pool.
I remember a few years ago when I was a patient in a hospital. There was a "Code Blue 320" announcement and several nurses ran into the room next to mine, room 320. A crash cart quickly followed. I didn't need ListVerse to figure out what that "Code Blue" meant!
In some beachs here in Brazil, when there's a missing child, people stay next to child and clap hands, alerting parents and/or lifeguard.
cool list. reminds me of "survivor" by Chuck Palanhuik. his mom kept teaching him what all these codes meant.
my sister worked at a sesame place theme park, and they had their own languge, named after the characters, and the color that goes with them:
code snuffy: a little kid pooped somewhere
code big bird: a kid peed
code elmo: a kid is bleeding
code oscar: a kid threw up
Well done to your sister. I get it too.
it was choke, sorry.
I like this list..funny!
Seriously, they had a Code Adam at the Walmart near me recently. They locked all the doors and didn't let anyone out or in. Within 5 mintues they found the boy by himself. He was with someone but they didn't catch the sick bastard who tried to take him. I personally think those types of people should roast slowly over an open flame!
Also I have to add, that this list reminded me of a T-Shirt my brother has.
On the front: NYPD Bomb Squad
On the back: If you see me running….try to keep up!
When I was a zookeeper, we had what was called a wallaby alert. It was a code for an escaped, dangerous animal. If a dangerous animal escaped, a radio message would go out to all the keepers, "Mr. Wallaby. Meet Mr. Lion (or appropriate animal) at the goat-pull (or appropriate location)." We never had a wallaby code while I was there. The most dangerous animal that got out of its pin was a small herd of goats from the petting zoo.
Whenever I'm in Walmart and hear a code Adam, my heart skips a little, even though my kids are teenagers, and way too obnoxious for anyone else to want. Nothing is scarier to a parent than a missing child.
isn't there a whole list of airplane tech codes somewhere? I guess that piggybacks onto the IT ones a little bit.
10-4.
This list will definitely have a 10-2.
I never knew about any of these codes, so I definitely learnt something new today.
Thanks JF for the very informative & cool list.
And I second StevenH (#24) about the name alignment.
Now I need to 10-0 (NZ police) & get myself 10-56ed.
My mom is a nurse and told me that "LOL" in nurse-speak means "Little old lady." Apparently these little old ladies can be troublesome, so the LOL on a chart is to warn the other nurses.
Awesome and quite informative list! I knew of several of these codes, but the rest I had no idea about. And now I know, thanks!
The Inspector Sands code sounds pretty mean to the costumers, if you ask me. It's like saying "Screw the costumers! Only the employees run for your lives and let the rest burrrrn!!!" or something along those lines.
Awesome….ima make sure i pay attention now whenever i hear a voice come over speakers….lol
I think we're supposed to know what code adam means… that's why they have the code adam stickers in the windows?
I used to manage a camera shop that developed photos in an hour. We had a couple of codes that we would use to let each other know that we had NUDE pictures in the store. I can't remember exactly what we used to say, but it was something like, "You need to check these pictures, there's "dirt" on them.".
If you ever took nude pictures to a ONE HOUR photo place to be developed let me just confirm your worst fears. YES! We ALL looked at your naked pictures!
In my store we NEVER copied the pictures, we just looked.
finally, a list i actually enjoyed! thanks jfrater
ive been missing your lists!
