What problem does it solve?
Provide per-number intelligence to determine carrier, line type, porting status, SIM swap, VoIP likelihood, and reassigned-number status so teams can prevent fraud, route messages/calls correctly, and improve verification decisions.
Core Features & Use Cases
- Carrier & Line Type Detection: Identify carrier name, mobile country/network codes, and whether a number is Mobile, Landline, VoIP, or other to choose the correct channel.
- Risk & Fraud Signals: Detect recent SIM swaps and VoIP likelihood to block or escalate risky verification attempts.
- Reassigned Number Detection (RND): Check disconnects relative to a contact date to clean lists and avoid sending to reassigned numbers.
- Use Cases: Fraud checks before verification, pre-send hygiene for marketing lists, routing decisions for voice vs SMS, and enriching contact records.
Quick Start
Request a lookup for +12025550134 including LineType and SimSwap using your chosen SDK or a direct HTTP POST to the lookup endpoint.
