Phone Number Lookup
- Quick Deploy
Look up a phone number to get different types of information including:
- Validation and Formatting. Detects invalid phone numbers and parses numbers into the standardized E.164 format
- Carrier. Detects line type (i.e. mobile, landline, voip*) and carrier.
- Caller name. Subscriber info, US only.
- [BETA] Line Type Intelligence. Enhanced line type and carrier detection.
More details in the Lookup API documentation.
For a production use case we recommend adding phone verification, which is a best practice for collecting phone numbers from your users in order to make sure they have control of the number.
See how to combine Lookup and Verify in this code sample for SMS verification with retry logic.
*Carrier VoIP detection is US only. Use Line Type Intelligence for global VoIP detection.
