Carrier Type Lookup (CTL™) Service

For companies such as telemarketers that need to avoid calling wireless numbers, Carrier Type Lookup screens numbers and identifies the types of carriers, landline or wireless, with nearly 100% accuracy. To initiate CTL, customers simply provide a list of telephone numbers and we determine which are serviced by landline carriers and which are serviced by wireless carriers.
