Announcing Phone Number Lookup API


Gabe Cabellon


What's happening?

We're excited to announce that our Phone Number Lookup API is now available! This functionality lets you send US and Canadian phone numbers through our API and have valuable network data behind them returned to you.

What do I need to know?

This is a brand new, API-only functionality that's been developed to help understand the landscape of the phone numbers our customers work with every day. You 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 telephone number (TN) or a 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 (Wireless co. X vs. Bandwidth) - this is the messaging provider for the phone number, not the voice provider
  • Mobile Country Code (if applicable)
  • Mobile Network Code (if applicable)

What do I need to do?
