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.
This tool applies the rules Data Legion uses before it matches a phone number: the phone library behind Android's dialer, plus filters for placeholder numbers. A number formatted here lines up with how numbers are matched in the Person Enrichment API.
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.
