While shopping, you’ve probably heard a store announcement over the intercom. Let’s be real—you likely tuned it out and have no idea what they said.

Next time you’re out shopping, take a moment to listen—it might just save your life. Sounds dramatic? Maybe, but it’s the truth.

 If you don’t work in retail, you might not know that many stores use color codes over the intercom, each with its own specific meaning.

According to Common Cents Moms, stores, including Walmart, use seven color-coded messages: Brown, Red, Green, Blue, Orange, White, and Black.

What are the Seven Shopping Color Codes and Their Meanings?

BROWN

When you hear code brown, it means that there is an active shooter on the premises. You need to find your way to an exit immediately and call 911.

RED

If you hear code red that means there is a fire of some type within the store

GREEN

This code means that there is an active hostage situation taking place.

BLUE

This code means that there is a potential bomb threat happening in the store.

ORANGE

Code orange means there is a chemical spill inside or outside of the store.

WHITE

Code White means there is some sort of injury or accident that has happened within the store.

BLACK

Code black means there is dangerous and severe weather in the area.

While the codes are intended for store employees who are trained to handle these situations, as a customer, it's just as important for you to know as well. You never know, it just might save your life.
