Can I keep my business phone number if I use an answering service?

Usually, yes. Many answering services — human or AI — work by having your calls forwarded to them, which leaves your number exactly where it is: with your phone company, on your bill, in your name. The number only changes hands if you port it, meaning you move it to the service’s phone provider. That can be fine too, but before you agree to either, ask who controls the number afterward and how you would take it back, and get the answer in writing. The number on your signs, your Google Business Profile and your business cards is an asset; treat it like one.

Forwarding, porting, or a new number

There are three ways a service can sit behind your phone, and they are not equally safe.

Forwarding keeps your line with your carrier and sends calls to the service — either every call, or only the ones you don’t pick up. You can switch it off any day. It’s the lowest-risk setup, and for many small businesses it’s all that’s needed; here’s how forwarding only the unanswered calls works.

Porting moves the number itself to the service’s provider. Owners do it when they want calls and texts handled in one system. The trade-off: your number now lives on someone else’s account, so leaving means porting it out again.

A new number from the service, printed on your listings in place of your own, is the arrangement to be most careful with. If the number customers know belongs to the vendor, ending the relationship can mean reprinting everything and losing every customer who saved the old number.

What the rules say about getting a number back

In a public notice dated September 22, 2025 (DA 25-878), the FCC stated that interconnected VoIP providers, resellers included, “must facilitate local number portability” and “must execute porting requests without unreasonable delay,” and its rules (47 CFR 52.34) bar agreements that prohibit porting. Interconnected VoIP is internet-based phone service that makes and takes calls with ordinary phone numbers; if the line behind your answering service is that kind, the notice applies to its provider. It doesn’t cover everything: a number used only for texting may not count. And a rule on paper is slower than a clause in your own agreement. This isn’t legal advice — if a contract looks like it traps your number, ask your own counsel.

Get it in writing before you start

Before you sign, ask the service to put these in the agreement or in an email:

• Whether your number will be forwarded or ported, and whose account it will sit on.
• That the number stays yours, and that they will release it promptly if you ask to move it.
• The exact steps to take it back, and anything you’d need from them to do it.
• Whether you can keep texting from it, and through what.

And one rule for yourself: never cancel your current phone service before a port is finished. A cancelled number can be hard to get back. If a service won’t answer these questions plainly, that tells you something too.
