💡 What is it

Outbound caller ID CNAM is what could display on the receiving number's device, representing more than the digits of a phone number, like a personal or business name. 

⚙️ How it works

1. NumberBarn only create CNAMs for our numbers by request. We do not report any information about you or your numbers to any of the CNAM databases by default. If you do not submit a CNAM value, only the telephone number will show up in the caller ID when you place outbound calls.
2. A CNAM can be a mixture of letters, numbers, and spaces totaling a maximum of 15 characters

📌 Things to Know

• There are several CNAM databases/vendors involved, and since CNAM display is ultimately the responsibility of the receiving carrier, it can take up to 30 days for the update to "take effect" due to things like caching and propagation
• As of January 2023, we now support CNAM on toll free numbers
  • If updated, the Toll-Free CNAM will only show up when you call landlines. It does not work with mobile numbers
• When you port a number to another carrier, the CNAM does not transfer with it. That said, most carriers should store your CNAM for about 30 days. If you port away, just contact your new carrier/service provider and ask them to set that up for you to minimize or eliminate any downtime with your CNAM record.
