What it does
Classifies a phone number as mobile, landline, VoIP, toll-free, or other
Takes a phone number and returns its line type and carrier. Covers mobile, landline, fixed VoIP, non-fixed VoIP, toll-free, and several other classifications. The line type changes what the number can be used for, so the result is shaped for routing decisions downstream.
When you’d reach for it
- ▸Filtering landlines out of a list before sending an SMS campaign.
- ▸Flagging non-fixed VoIP numbers in a new-customer signup flow for additional review.
- ▸Routing calls differently depending on whether the destination is a mobile or a landline.
