How this service works
Parse, validate and canonicalize a phone number using Google's libphonenumber metadata. Query: number (required; E.164 like "+14155552671" or national like "(415) 555-2671"), country (optional ISO 3166-1 alpha-2 like US/GB/JP — required when number is not E.164). Returns {input, valid (matches a real number range), possible (right shape/length), e164, national, international, rfc3966, country, countryCallingCode, type (mobile|fixed_line|fixed_line_or_mobile|toll_free|premium_rate|shared_cost|voip|personal_number|pager|uan|voicemail|unknown), possibleCountries[]}. Returns valid:false (not an error) for unparseable input.
Output
Returns a JSON object with: input (original), valid (boolean — matches a real number range), possible (boolean — right shape/length), e164 (e.g. +14155552671), national, international, rfc3966, country (ISO code), countryCallingCode, type (mobile|fixed_line|fixed_line_or_mobile|toll_free|premium_rate|shared_cost|voip|personal_number|pager|uan|voicemail|unknown), and possibleCountries[]. Returns valid:false (not an HTTP error) for unparseable input.
Example use cases
Example prompt
“Can you validate and normalize the phone number '(415) 555-2671' for the US — is it a real number, what's its E.164 format, and is it a mobile or landline?”
Technical details
Endpoint
GEThttps://2s.io/api/phone/normalizeWhen to prefer
Use this endpoint when you need authoritative phone number validation backed by Google's libphonenumber metadata — the gold standard for phone parsing. Prefer it over regex-based validation when you need to distinguish valid (real number range) from merely possible (right length/shape), determine the phone type (mobile vs. landline vs. VoIP), or obtain clean E.164/international/national/RFC3966 formatted output from messy user input.
Side effects
- Unparseable number: returns valid:false and possible:false rather than an HTTP error
- Missing country code when number is national format: may return invalid result or fail to parse correctly
- Invalid country code provided: parsing may fail or return unexpected results
- Number outside any known range: valid:false, possible:false with empty possibleCountries
- Network/payment failure: HTTP 402 if payment not provided, HTTP 4xx/5xx on infrastructure errors
