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 phone number in E.164 format, the detected country calling code (e.g. +1, +44), the geographic region or country name, and a boolean or status indicating whether the number's length is valid per the E.164 standard.
Example use cases
Validate user phone at signup
“A user just entered +447911123456 during registration — can you parse it to E.164, confirm the country code and region, and tell me if it's a valid length before we store it?”
Normalize international customer contacts
“I have a customer phone number +33612345678 — parse it into E.164 format, extract the country calling code and region, and verify it meets the E.164 length rules.”
Check lead data before CRM import
“Before importing this lead's phone number +819012345678 into our CRM, can you validate it against E.164 and tell me the region it belongs to?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/phone-parseWhen to prefer
Choose this endpoint when you need to parse, normalize, and validate a single phone number to E.164 format with country detection at low cost ($0.002 per call). Ideal for real-time form validation, CRM data enrichment, or pre-flight checks before sending SMS. Prefer this over a full-featured identity verification service when only number format and region detection are needed.
Side effects
- Number missing leading + or country code — returns parse error or invalid format
- Number too short or too long for the detected country — fails length validation
- Unrecognized or unsupported country calling code — returns unknown region
- Completely non-numeric input — returns parse error
- Missing request body or phone field — returns 400 bad request
