Get to know SOS Codes for Emergency Alerts from Around the World

The SOS code was created by humans to be able to convey a danger or emergency signal as quickly as possible. Only with a sign or one word can it be known that someone or more is in danger and needs help.

In addition, the SOS code also has various variants that are tailored to the needs. Some of them have meanings that are difficult for others to understand because they are not supposed to be known to many people.

The following are a number of SOS codes that indicate an emergency situation.

Ten Codes

Ten Codes or Ten Codes is a code developed by United States law enforcement since 1937. But gradually, this code was cracked by the public. The password with the number 10 in front of it refers to a dangerous situation, for example, the code 10-187 which means a murder has occurred, or 10-31 which means that a crime is taking place.

Time Check

Sounds like telling people to check the time. But in fact there is a terrible meaning tucked away in it, for example, “Check the time: it is now 12.00”, which means there is a bomb threat around the area.

In the UK, the time check code can also be spelled out by the name, “Mr. Jet”. This code is usually stated at the court or movie theater and indicates that people in the building must be evacuated immediately because of a bomb threat.

“Bravo, Bravo, Bravo”

Bravo code is commonly used at airports or ships. When someone mentions this code, it means an emergency situation is in progress. Everyone is usually asked to remain silent to facilitate the examination. While the Bravo Code on the ship indicates a fire hazard.

Doctor Brown

The announcement of “Doctor Brown” at the hospital signaled that security forces were asked to be on alert due to threats to staff by patients or people around the hospital. In addition there is also Code Silver which means a threat with a weapon.


7500 is a password that is passed on when the flight is experiencing or there is a threat of hijacking. In addition, there are also similar passwords, such as 7600 which means loss of communication signal, or 7700 which is a code for general emergencies.

Code Adam

Code Adam indicates that a boy is missing. This code was inspired by the disappearance of a boy named Adam Walsh in 1981 who was kidnapped while shopping at the Holywood Mall with his mother. Two weeks later, his severed head was found in the sewer.

To commemorate this tragic event, Walmart created Code Adam which refers to the disappearance of a child, as well as an order for all store employees to immediately conduct a search around the Walmart location.

“Zulu, Zulu, Zulu”

Zulu is a voyage code that indicates that there is a fight on a ship. This code can also be combined with other passwords, such as “Bravo Zulu” or “BZ” which means that the action goes well and smoothly. On the other hand, if you add the word NEGAT at the beginning of the code “Bravo Zulu”, it means “doesn’t end well”.

Color Code in Hospital

Hospitals also often use color codes. For example, “Code Pink” has another meaning, namely a warning to employees that a baby will be born soon without a specialist midwife. While in several other hospitals, this code indicates that they are on alert because there are patients who are under the influence of drugs.

When a patient disappears, the hospital will call out “Code Yellow”. This code is also a reference for employees to be prepared because patients with serious injuries or victims of natural disasters are arriving. There is also “Code Brown” which means a readiness order for an event that results in many casualties.

“Mayday! Mayday!”

Code “Mayday!” always alert to an emergency on the plane. That said, this password was created due to a misspelling. In 1923, Frederick Mockford was suddenly tasked with finding a single word that could represent an aviation emergency.

At first he wanted to use the French word “M’aidez”, which means, “Please”. But because it sounds like “mayday” finally this word is used until now.

Code Using Color

Codes using the term color must also often be heard in movies. In real life, the US military uses the code “Code Black” which means there is a bomb threat or suspicious package.

There is also “Code Purple” which is usually used when a child is kidnapped, while “Code Pink” is a code that specifically explains that the missing child is still a toddler.

It’s not just hospitals, military, or airlines that have SOS codes. Grab also has support features that indicate that users are experiencing an emergency and need help as soon as possible.

This feature that you can find in the Grab application menu stack will automatically notify the three emergency contacts that you selected earlier. Once the emergency button is activated, these contacts will receive notifications and text messages from Grab about what to do to be able to contact the pusher and the authorities.
