Want to have your name or your company name to show up when you call from your OpenPhone number? No problem.

We've been working with our carrier partners on allowing this in OpenPhone and are currently piloting this functionality in beta.

But first, a little bit about what an outgoing caller ID (or CNAM) is and how it works.

What's an outgoing caller ID or CNAM?

CNAM, which is short for Caller ID Name, is the name of the person or business placing a phone call.

How does an outgoing caller ID or CNAM work?

Carriers populate one of several authoritative caller ID databases with subscriber data. Now when you get an OpenPhone number, we'll be able to do this for you.

Carriers also consume data from these databases. If you ever saw the name of the caller on your screen without having that person in your address book, your carrier looked up their number in one of these databases.

Can I put anything on my caller ID?

No. Otherwise, it would be one big mess. The CNAM or your outgoing caller ID can be a maximum of 15 characters in length, and can only contain letters, numbers, and spaces. Private, Unavailable, and Unknown are not allowed.

Also, you need to have authorization to use the name you'd like to show up on your caller ID. Otherwise, anyone can pretend to be the US Government.

Are there any limitations I should be aware of?

Each carrier has its own policies regarding caller ID. So while we submit your information to caller ID databases, it is not possible for us to guarantee it will display correctly every time for everyone. If a carrier is hitting a database that’s not up to date, it can display wrong information, or if they don’t hit it at all, it won’t display.

Don't worry, if you do not have a custom caller ID set up or a carrier doesn't look up caller ID information, your OpenPhone number will show up to people you call.

How much time does it take to update my caller ID information?

We will request updates to CNAM records weekly. From the time of the update, it sometimes takes 4-5 days for your caller ID information to start showing up.
