How this service works
Parses loosely formatted phone number input and returns its E.164 standard representation, country, and line type, with a default-country hint for numbers missing a country code. Built for lead deduplication, SMS delivery systems, and validation steps that reject malformed numbers before they hit a paid messaging API.
Output
Returns the E.164 formatted phone number (e.g. +14155550132), the detected country (ISO code), and the line type (e.g. mobile, landline, VoIP), enabling downstream validation or routing decisions.
Example use cases
Example prompt
“Can you normalize this phone number to E.164 format and tell me its country and line type — the number is '(415) 555-0132' and it's a US number?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/e164-phone-formatWhen to prefer
Use this endpoint when you need to normalize phone numbers to E.164 before passing them to a paid SMS/calling API, when deduplicating leads by phone, or when validating user-submitted phone input across international formats. Prefer this over rolling your own regex or using a general-purpose library when you also need line-type classification and country identification in a single call.
Side effects
- Malformed or completely unrecognizable number string returns a validation error
- Missing country code on a national-format number with no default-country hint may fail to resolve
- Ambiguous number formats for some regions may produce incorrect country assignment
- Numbers that look structurally valid but are unallocated may return unknown line type
