E.123

e.123 is a standard way people can format their contact information, like a phone number or email, so that other people can easily understand and use it. It's like using a secret code that everyone understands so they can quickly find the information they need to get in touch with you.

For example, if your phone number is (555) 123-4567, you could write it in e.123 format like this: +1 555 123 4567. The plus sign at the beginning means the number is international, and the spaces separate the number into groups so it is easier to read.

Using e.123 makes it easier for people from different countries to understand and use your contact information, even if they speak different languages or use different phone formats. It's like a universal language for our contact information so we can all stay connected!
