Phone number formatter
Turn a number written any way into the format apps and APIs expect.
What is the correct format for a phone number?
For apps and APIs, E.164: +[country code][national number], digits only after the plus, no trunk zero. Displayed formats add spaces or parentheses, but the digits are the same.
Common mistakes
- Keeping the national trunk prefix (0 in the UK, 0 in Brazil's old formats) after the country code.
- Picking the wrong country in the app's drop-down, so the code goes nowhere.
- Typing the country code twice.
