What is CNAM?

Modified on: Fri, 26 Sep, 2025 at 5:04 AM

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:

Go to sub-account Settings > Phone Numbers > Trust Center.
Click on CNAM (voice)
start registering

Benefits at a Glance

CNAM	Displays your business name on outgoing calls	Improves recognition and trust, leading to higher answer rates


Note: CNAM doesn't remove nuisance labels, but accurate caller information can enhance answer rates.

Ensure your number correctly displays your business name on the caller ID.
Work with your carrier to register or update your CNAM records.

Any entity with a business registration number—including sole proprietors with an EIN—may sign up for CNAM. An EIN is mandatory, whether you’re a one-person operation or a larger, registered brand.

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.
