How this service works
Validates a phone number and returns whether it's valid, reachable, carrier info, and caller name.
Output
Returns whether the phone number is valid, whether it is reachable, the carrier associated with the number, and the registered caller/owner name. Likely includes the formatted number and possibly line type (mobile, landline, VoIP).
Example use cases
Verify customer phone at signup
“Before we onboard this new user, can you validate their phone number +12125559876 and confirm it's real and reachable, and tell me what carrier it's on?”
Detect fake phone numbers in leads
“I've got a suspicious lead who gave us the number +13105550001 — can you check whether it's a valid, reachable number and who the carrier is?”
Caller identity lookup for CRM
“Can you look up the phone number +16175558432 and tell me the caller name and carrier so I can update the contact record?”
Technical details
Endpoint
POSThttps://x402.orthogonal.com/fiber/v1/validate-phone/singleWhen to prefer
Choose this endpoint when you need a single-call phone validation that combines validity checking, reachability, carrier identification, and caller name lookup in one step. It is especially useful for fraud prevention, lead verification, CRM enrichment, or pre-flight checks before sending SMS messages. Prefer this over basic format-only validators when you need real carrier and caller data, not just syntax validation.
Side effects
- Invalid or malformed phone number returns a validation error
- Number not found in carrier database returns empty or null carrier info
- Very new or uncommon numbers may lack caller name data
- Rate limiting or payment failure may return 402 or 429 error
- Non-E.164 formatted numbers may be rejected or produce unreliable results
