How CNAM works
When you place a call to someone, your CNAM information will be transmitted with your call to the receiving party. If the person you are calling has caller-ID service, they will see your caller-ID name and number.
Generally, the caller-ID number is almost never wrong because the caller-ID number is almost always sent with the call. However, to display the CNAM to the receiving party, the receiving telephone carrier must first look up your CNAM in a database using your phone number.
Why your CNAM name may not be displaying properly
For most phone carriers, there’s a cost associated with either querying a 3rd party CNAM database or keeping their own CNAM database up to date. Some telephone carriers have almost immediate access to the most up to date CNAM information, while others may not have access to this information for several months or longer.
Matters are further complicated with carriers having more than 20 different CNAM databases that do not all have the same data. Depending on the location and terminating carrier, certain people you call may correctly see your CNAM while others may not.

Please provide current CNAM if possible as there is not an easy way for us to see their current caller ID.
NOTE: CNAM is limited to 15 characters including spaces. Special characters cannot be used.
