Lookup Line Type Intelligence is now Generally Available

Lookup Line Type Intelligence helps you determine the line type of a phone number (e.g. mobile, landline, VoIP) so you can reduce fraud, block identity bots, and improve messaging conversion rates. As part of this GA release, we’re introducing a new Line Type Overrides API, which gives you more control by allowing you to correct inaccurate or outdated classifications in real time.

New: Line Type Overrides API

We’ve heard from customers that occasionally the line type returned is inaccurate. The new Overrides API enables you to:

• Create an override for a phone number’s type field (Supported values: mobile, landline, fixedVoip, nonFixedVoip).
  

• Retrieve, update, or delete overrides as needed.
  

• Optionally include a reason for auditability.
  

Overrides are account specific and region bound. Once created, overrides automatically apply to all future Lookup responses for that number on your account in the same region.
