CarrierLookup

0 reviews

CarrierLookup provides original carrier and phone-number allocation information for business contact-data workflows. A web dashboard and REST API support real-time single-number and small-batch requests, while asynchronous bulk file tasks produce downloadable CSV results. Returned fields can include the originally allocated carrier, underlying carrier, line type and allocation geography. A real-time MCP integration is available for compatible clients. Carrier information describes original number allocation rather than the current network after porting; geography is number-range allocation context rather than a device location. Results do not establish number reachability or owner identity.
