Can You Keep Your Phone Number When You Move to Another State?
Your cell number can usually come with you across state lines. A landline number usually can't. Here's what an out-of-state area code changes, and how to switch carriers without losing the number.
Short answer: a cell number usually comes with you. A landline number usually doesn't. The California Public Utilities Commission puts it plainly: you can keep your wireless number when you move, but a wireline number can't follow you once you leave the area where it was assigned.
So if you're driving a moving truck from Sacramento to Austin with a 916 number on your phone, you don't have to give it up. What changes is everything around the number: who recognizes it, what a landline caller pays to reach you, and what to do if you switch carriers along the way.
Why the rules treat "switching" and "moving" differently
The FCC's rules define number portability as keeping your existing number, at the same location, when you switch from one carrier to another. That's the right carriers must honor. Moving is a different concept. The same rules define location portability separately, as keeping a number when you move from one physical location to another.
That's why forum answers seem to contradict each other. A wireless number can stay with you, as the CPUC says, but the porting right itself is written around staying put. Even a carrier that accepts most numbers warns that some may not be eligible based on geography, service area coverage, technology or ownership of the line.
Landlines: the local-area limit
A home phone number is tied to its area. You can keep a wireline number if you move within the same area where it was assigned. Move away from that area, and you can't keep it as a wireline number.
There's an exit, though. A wireline number may be portable to a wireless or VoIP provider outside those local boundaries, and in many cases a home number can move to a wireless phone. If Grandma has had the same home number since 1985, ask a mobile or VoIP provider whether it can take the number before the old line is shut off.
What an out-of-state area code changes day to day
911 calls
It's a common worry, and the rules have moved on. Nationwide wireless carriers had to deploy location-based routing for 911 voice calls on their 4G LTE and 5G networks by November 13, 2024, and smaller carriers by May 13, 2026. Under that rule, the carrier uses location information to route the call. Your area code isn't what decides where a wireless 911 call goes.
Still, don't count on the dispatcher seeing where you are. The California PUC warns you can't be certain operators will receive your location from a wireless call, and tells callers to state the location right away and give their wireless number in case the call drops. Home internet phone service follows its own 911 rules, which our guide to VoIP and 911 covers.
Callers and long distance
Your contacts won't notice anything. New ones might. A plumber or a school office in your new town sees a code from another state on the caller ID and may not realize you're local. On the cost side, the CPUC notes that keeping a wireless number can mean extra long-distance charges unless your plan is national. For wireline service, calls that cross state lines count as long distance, which matters when a neighbor or local office in your new state calls your old-state number from a landline.
Your area code only reflects where the number was first assigned, as our explainer on how US area codes work describes. It says nothing about where you live now.
Moving and switching carriers at the same time
If you're also changing carriers as part of the move, the order matters. Contact the new company first, and do it before you cancel the old service. Verizon's own support page spells out the risk: disconnect the line before the number moves, and you have to reactivate it before the new carrier can take it.
- Leave the old line active until the new carrier confirms the transfer is done.
- Have the active number and your current carrier's account number ready.
- Get a Number Transfer PIN from your current carrier's app or website. It isn't your 4- or 6-digit account PIN.
- If you're leaving Verizon, turn off Number Lock first.
- Check what you still owe. Verizon may charge an early termination fee on lines with an unfinished minimum term, and any remaining device payment balance has to be paid off.
Don't generate the PIN weeks ahead of moving day. Verizon's expires after 7 days.
How long does it take? For numbers coming into Verizon, the company quotes 4 to 24 business hours for a mobile number and 2 to 10 business days for a landline. For simple wireline-to-wireline and intermodal ports, FCC rules set one business day unless the new provider or the customer asks for longer.
Keep the old number, get a local one, or carry both
Keep the old number if it's the one on your bank accounts, your doctor's file and every two-step login you own. Changing it means updating all of them.
Get a local number if your phone is part of your work in the new state: real estate, contracting, anything where a stranger decides whether to pick up. Browse US area codes by state to see which codes cover your new city, such as the Texas area codes around Austin.
Or carry both. On iPhone, Dual SIM gives you two active phone numbers for calls and texts. To use two different carriers, the iPhone must not be locked to one carrier, or both plans must come from the same carrier. Someone moving from Miami to Dallas could keep the 305 number for family and old clients, add a Texas line for new ones, and look up both on our Florida area codes and Texas pages.
FAQ
Can I keep my cell phone number if I move to another state?
Usually, yes. The California PUC says you can keep your wireless number when you move, though long-distance charges may apply without a national plan.
Can I take my landline number to a new state?
Not as a landline. You may be able to port it to a wireless or VoIP provider instead.
Will 911 work with an out-of-state area code?
Yes. Wireless 911 calls are routed using location information, not your area code. Say where you are anyway, since the location may not reach the operator.
Should I cancel my old service before switching carriers?
No. Start with the new carrier and keep the old line active until the number moves.
