Can you keep your business phone number when you switch providers?
Summary
Usually, as long as you stay in the same geographic area. The FCC says numbers can move between wireline, IP, and wireless providers, and the port starts with the new provider, not the old one. Keep the old service running until the port finishes, because the FCC specifically warns against canceling it before the new service is in place.
How the port works
You contact the new company and give it your 10-digit number plus whatever else it asks for. Once you've requested service there, your old company cannot refuse to release the number, even if you owe a balance or an early termination fee. You still owe that money, so read the old contract before you start. Companies may charge a porting fee, and the FCC says you can ask whether it can be waived or negotiated.
If you're moving to a new area, you may not be able to bring the number with you.
How long it takes
FCC rules require simple ports to be processed in one business day. A simple port, in the FCC's words, generally involves no more than one line and no complex adjustments to switching equipment. A company moving a main line and a block of direct dials often won't fit that description, so plan on more than a day.
Wireless-to-wireless ports can be usable within a few hours. Wireline-to-wireless can take a few days, and for a while two phones may share the same number.
A sequence that avoids dead air
- Build the new system while the old one still carries your calls: users, extensions, hours, auto attendant, ring groups. Test with temporary numbers if the provider issues them.
- If you text customers, file your A2P 10DLC registration now. TCR says campaign review can take one to four weeks.
- Request the port from the new provider.
- After the numbers land, call in from an outside phone, call out and check caller ID, and walk through the routing.
- Cancel the old service last, once calls are arriving on the new system.
911 on the new system
Register the address that 911 will receive for each site and phone in the new system before cutover. On a multi-line system, Kari's Law requires that anyone can dial 911 without a prefix such as 9 and that a 911 call notifies a central point where someone will see or hear it. That applies to systems manufactured, imported, first sold or leased, or installed after February 16, 2020.
To confirm 911 works, don't dial it. 911.gov says test calls are scheduled through your local 911 center's non-emergency number, depending on the center's workload.
