What is CNAM?
Overview
CNAM (Caller Name Presentation) is a feature in the U.S. public telephone network that associates your phone number with a business or personal name. When you make an outgoing call, this name may be displayed on the recipient’s device.
Why CNAM Matters
- Builds trust with your contacts - Increases the chance that calls are answered - Does not remove nuisance labels - Business name display is not guaranteed (depends on the recipient’s carrier policies)
Requirements
- An EIN (Employer Identification Number) is mandatory for CNAM registration.
- Both sole proprietors and larger businesses with an EIN can register.
How to Register or Update CNAM
You can register or update your CNAM records directly from the Trust Center—no need to go through your carrier.
Steps: 1. Go to sub-account Settings > Phone Numbers > Trust Center. 2. Click on CNAM (voice) 3. start registering

Tip: CNAM does not replace SHAKEN/STIR. For best results, use both together—SHAKEN/STIR authenticates your caller ID, while CNAM displays your business name. Related Articles
