How this service works
Parse a phone number to E.164, detect its country calling code and region, and validate length against the E.164 standard. Provide a number with a leading + and country code.
Output
Returns the E.164-normalized phone number, the detected country calling code (e.g. 1 for US/Canada, 44 for UK), the geographic region or country name, and a boolean or status indicating whether the number's length is valid per E.164 specifications.
Example use cases
Validate user phone at signup
“Before storing this new user's phone number +447911123456, can you check it's a properly formatted E.164 number and tell me what country it belongs to?”
Normalize CRM phone data
“I have a phone number +33612345678 from a lead in my CRM — can you parse it to E.164, confirm the country calling code and region, and tell me if the length is valid?”
Detect region for SMS routing
“I need to route an SMS to +5511987654321 — can you parse it and tell me the country code and region so I can pick the right carrier?”
