FAQ
- What is E.164 format?
- E.164 is the international standard for phone number formatting defined by the ITU. It starts with a + followed by the country code and subscriber number, with no spaces or dashes, e.g. +14155552671. Maximum 15 digits total.
- What is the difference between national and international format?
- National format uses the local convention for displaying a phone number within its own country (e.g. (415) 555-2671 in the US). International format adds the country code with a + prefix and may use spaces or dashes (e.g. +1 415 555 2671).
- Why might my phone number not format correctly?
- This tool applies hardcoded formatting rules for 10 supported countries and validates digit count against expected lengths. Numbers with incorrect digit counts for the selected country will be flagged as invalid. Formatting does not verify if the number is actually assigned or reachable.
