Calling ID Lookup/Caller Name Lookup

Calling ID Lookup is a function that allows Bandwidth customers to use a phone number from an inbound call to search for the corresponding caller ID. When Bandwidth delivers an inbound phone call, our customers can use an API function called ‘CNAM Lookup’ to input the phone number, and query the caller ID. You can think of it as ‘do it yourself’ caller ID.



Using Calling ID Lookup with Bandwidth

Bandwidth makes an API available that acts as a query service for our customers to input a phone number, and return the caller ID. Bandwidth uses a REST API to make this process fast and easy to use for our customers.
