Bandwidth now offers a phone number lookup API!

May 25, 2021 Phone Numbers API

With this new product offering, you’ll now be able to send us single or multiple phone numbers through an API resulting in returning the most important metadata behind those phone numbers.

What’s happening?

We are introducing the new Telephone Number Lookup API! Customers now have the ability to send US and Canadian phone numbers through our API and have valuable network data behind the phone numbers returned to them!

What do I need to know?

This is brand new, API-only, functionality that has been developed to help understand the landscape of the phone numbers which our customers work with every day. Customers can use this for onboarding pre-validation (mobile vs. landline), sender database maintenance, or to help improve message deliverability. This new tool allows lookup on a single TN or batch of TNs up to 100 at a time. The response will include the following:

  • E.164 Formatted TN
  • Formatted TN
  • Country
  • Line Type (e.g. wireless vs. wireline)
  • Line Provider (e.g. AT&T)
  • Mobile Country Code (if applicable)
  • Mobile Network Code (if applicable)

What do I need to do?

Take advantage of this new product by contacting your sales representative to get started.
