What is Telnyx Number Lookup?
Telnyx Number Lookup is a REST API that returns live data about any phone number: the carrier currently serving it, line type (mobile, landline, VoIP, toll free), porting status and LRN, caller ID name (CNAM), and MCC/MNC codes for mobile numbers worldwide. Optional data sets include Enhanced Caller Name and Caller Identity, which returns the name and postal address behind US and Canadian numbers with a confidence score.
You request only the data sets you need and pay per query, from $0.0015 per LRN dip. Lookups query live telecom databases, including HLR for mobile numbers, and support bulk processing of millions of numbers. SDKs are shown for Python, Node and Ruby.
It fits developers and businesses that need to check that numbers can receive SMS before sending, screen VoIP numbers at signup to cut down fraud and SMS pumping, clean CRM records, or pass caller context to contact centers and voice AI agents.
