CNAM: Displaying Your Business Name on Caller ID
CNAM (Caller Name Presentation) is what lets a recipient see your business name — instead of just a bare phone number — when you call them from a US number.
Registering
- Go to Settings > Phone System > Trust Center.
- Select CNAM (Voice) and start registration.
- Enter your business details. You'll need an EIN (Employer Identification Number) to register — this applies whether you're a sole proprietor or a larger business.
Why your name might still not show up
CNAM registration is not a guarantee, even after approval. In practice:
- US carriers pull caller-name data from any of several different CNAM databases, and many use the cheapest source available — which can be outdated or simply not include your registration.
- Overall CNAM display reliability across the US is low; a large share of calls never show a registered name at all, regardless of provider.
- On mobile phones, CNAM lookups are often a premium carrier feature that many plans don't include — and since the recipient likely already has you saved as a contact if they know you, carriers have less incentive to support it broadly.
In short: register it because it helps when it works, but don't rely on it as your only reputation fix. Pair it with What Is SHAKEN/STIR? and Voice Integrity — see Caller Reputation & Spam Prevention — for a more complete approach to being recognized as a legitimate caller.
