Have you ever noticed the announcements over the intercom while shopping at a Pennsylvania Walmart?

They may be announcing sales or something way more serious.

If you tend to not listen to them, it might be time to start paying attention.

Did you know that Walmart stores use secret codes that alert employees to different situations?

These codes can be a combination of colors, numbers, and words.

While they’re meant for staff, knowing what they mean could be super important for shoppers, too.

Here are some important color codes to watch out for:

Wow. This was a big time eye-opener for me.

From now on, I’ll be listening much more carefully during my next Walmart trip.

Stay safe and be alert while you shop.
