# Phone number tools

Four small utilities we use ourselves when a sign-up misbehaves. They run in your browser; nothing is sent anywhere.

## How do I format a phone number for verification?

Write it in E.164: a plus sign, the country calling code and the national number with no spaces, leading zeros or punctuation, e.g. +447911123456. The formatter below does it for any country and flags numbers with the wrong length.
