Phone Number Formatter
Convert a phone number in any format to E.164, plus its international and national forms. Everything runs in your browser, so the number never leaves your device.
The country is used only when the number has no +country code.
Enter a phone number in any format and press Format Number.
Why format phone numbers as E.164
The same number arrives in a CRM as 415.867.5309, (415) 867-5309 and +1 415 867 5309. Stored as typed, those look like three contacts. Converted to E.164, all three become +14158675309, so duplicates collapse and lookups match.
Formatting uses the phone library behind Android's dialer, the same rules Data Legion applies before it matches a number, so a number formatted here lines up with the Person Enrichment API. Placeholder numbers get a warning; the API skips them.
Cleaning a whole column in code? The free Clean API normalizes phone numbers, emails, names and social URLs to the same format with any Data Legion API key.
