ELI5: Explain Like I'm 5

E.164

Hi there! E.164 is a special way of giving phone numbers so that everyone around the world can understand and use them. Imagine playing a game of telephone but everyone speaks a different language. It would be really hard to understand each other, right? Well, E.164 is like a special language for phone numbers.

When we use E.164, we start with a "+" sign and then a country code (like +1 for the United States or +44 for the United Kingdom). Then we add the phone number itself, which can be up to 15 digits long, depending on the country. This way, no matter where you are in the world, you can understand and call the phone number, just like you would with your own phone number.

So, that's E.164 - a special way we can all understand and use phone numbers no matter where we are in the world!
