Carrier Lookup identifies which telecommunications company currently serves a phone number. This is essential for routing, billing, and fraud detection since over 30% of numbers have been ported to different carriers than their original assignment.
Why Carrier Lookup
- Call routing — Send through correct carrier paths
- SMS delivery — Route to appropriate gateways
- Billing — Apply correct carrier rates
- Fraud detection — Identify VoIP carriers
