Understanding CNAM (Caller ID)

What is CNAM Caller ID?

CNAM (Caller ID) allows you to add a Display Name to your outbound calls. With today's steady stream of scam calls, displaying your business name fosters immediate trust and opens doors to meaningful communication.

Setting up your CNAM Caller ID

Prerequisite(s)

In order to register your CNAM, you must have completed the following steps:

Configuring Caller ID

Please contact our Support team with the following information:

  • Short Caller ID which should be displayed.
    • 15 character alphanumeric display name that will show on the consumer device when a call is placed. This name must start with a letter.
    • This should include your business name or another clear indicator of who is making the call.
    • It must be a name that can be associated back to your business or brand. Otherwise, it may be rejected by the carrier.

Carrier Limitations to be aware of

1. Revenue.io and our Carrier Partner can't guarantee that a Caller ID is displayed. This is the responsibility of the terminating carrier (number being called) which must also support Branded Caller ID. Some carriers either do not support this functionality or do not frequently update their databases.

2. In Canada, Branded Caller ID is not currently supported. The Caller ID will be passed to the terminating carrier via a SIP Header and may be displayed if the terminating carrier supports CNAM. Some routes in service with Canadian carriers rely on legacy hardware which do not support the passthrough of SIP headers.

4. Configuring a Caller ID will not overwrite any "Spam Likely" designation a number has. However it may reduce the chance of your numbers being flagged as spam by making them more recognizable.
