CNAM Lookup

Check the Caller ID Name (CNAM) for any numbers.

CNAM is short for Caller ID Name – the “name” of a caller that is displayed instead of a phone number. This name is registered with the provider and then displayed on capable recipient telephones. This is usually done by larger companies and institutions. However, smaller companies also make use of it to avoid that calls are ignored due to unknown numbers.

Our CNAM lookup first queries the network operator’s databases directly. If this does not deliver a satisfactory result, other sources are used. This allows us to achieve global coverage. The CNAM query allows you to request the Caller ID Name for any telephone number. Of course not every phone number has an entry. For numbers without CNAM, there are different possible outputs. Depending on the registered data the output can be the country or region or the network operator with which the telephone number is registered.
