Setting your Caller ID Name (CNAM)
Recipients are more likely to answer a call when they see a business name instead of a raw phone number. Here's how to set yours.

Caller ID Name — usually called CNAM — is the short text label that appears next to your phone number when you call someone. A CNAM that reads "ACME DENTAL" is far more likely to be answered than a bare 10-digit number.
Best practices
Use a name your recipients will recognize — usually your brand
Keep it to 15 characters or fewer for consistent display across devices
Use uppercase letters
No phone numbers, URLs, or special punctuation beyond a hyphen
Important to know
CNAM is optional but highly recommended
CNAM is turned off by default when your numbers are first provisioned — we recommend turning it on
Not every phone or carrier displays CNAM, but most do
A "Spam Likely" label overrides CNAM. CNAM doesn't prevent spam labeling — it just helps reduce it
How to set it
Go to your dashboard → Phone Numbers → select the number → Caller ID. Type in your business name and save. The update typically shows within 24 to 48 hours.
