You do not own your phone number in any legal sense, and the short answer to “do I own my phone number” is that the number is a public resource administered by the Federal Communications Commission, licensed to you through your carrier’s service agreement. What you do own is a set of federal rights: you can take the number with you when you change providers, lock it against fraud for free, and transfer it to another person through your carrier. Those rights are strong enough that for daily purposes the difference rarely matters, until something goes wrong.
Who Actually Owns Your Phone Number
Under 47 U.S.C. ยง 251(e), the FCC has exclusive jurisdiction over telephone numbering in the United States and is responsible for making numbers available on an equitable basis.1Office of the Law Revision Counsel. 47 U.S. Code 251 – Interconnection The agency delegates blocks of numbers to carriers, and carriers assign individual numbers to customers. Your number stays part of a public pool the entire time you use it.
What you hold is a right to use a specific number for as long as you keep an active account in good standing. Stop paying, stop using the account, or close it, and the number returns to the pool for someone else to receive.
Your Right to Keep the Number When You Switch Carriers
The strongest right you have is portability. The Telecommunications Act of 1996 established Local Number Portability, and the FCC has built the rules out from there.2Federal Communications Commission. Telecommunications Act of 1996 Your number follows you, not your carrier.
Porting works across wireline, wireless, and VoIP providers. You can move a landline number to a cell phone, a cell number to a VoIP service, or any other combination, so long as you stay in the same geographic area.3Federal Communications Commission. Porting: Keeping Your Phone Number When You Change Providers If you relocate to a different part of the country, you may not be able to bring your number along. Some rural wireline providers can also obtain state waivers from the porting requirement, though this is uncommon.
How the Transfer Works
Contact the new carrier, not the old one. The new provider handles the request. You’ll need your current account number, any PIN or password on the account, and the billing address on file. Do not cancel your old service first, because canceling releases the number back into the pool and can make it unavailable to port.
For a simple single-line port, FCC rules require carriers to complete the transfer within one business day.4eCFR. 47 CFR 52.35 – Porting Intervals More complex ports involving multiple lines or bundled services can take up to four business days.
Your Current Carrier Cannot Hold the Number Hostage
Your current carrier cannot refuse to release your number, even if you owe money or face early termination fees.3Federal Communications Commission. Porting: Keeping Your Phone Number When You Change Providers You still owe whatever you owe, and the carrier can bill you or send the debt to collections, but the number cannot be used as leverage. If a carrier stalls or refuses a legitimate port request, you can file a complaint with the FCC.
When You Can Lose the Number
The gap between “using” and “owning” shows up when the account fails. The most common cause is non-payment. When you stop paying and your carrier terminates service, the number is disconnected. FCC rules require carriers to wait at least 45 days before reassigning the number to someone else.5Federal Communications Commission. Reassigned Numbers Database Some carriers hold numbers for 90 days or longer, but that is a matter of carrier policy, not a right. Once the number goes to a new subscriber, you have no legal claim to get it back.
Extended inactivity produces the same outcome. Prepaid accounts are especially vulnerable. If you don’t make a call, send a text, or add funds within your carrier’s defined activity window, the account goes dormant and the number is eventually released. Each carrier sets its own inactivity threshold, so check your plan terms if you keep a secondary phone you rarely use.
Protecting the Number From Port-Out Fraud and SIM Swapping
Not owning your number becomes genuinely dangerous when a scammer convinces your carrier to transfer it to their device. Once they control the number, they can intercept two-factor authentication codes, drain bank accounts, and lock you out of your online life. The FCC issued rules addressing this that took effect in late 2023.
Wireless carriers must use secure authentication methods before completing any port-out request or SIM change. Those methods cannot rely on easily obtained information like your birthday, recent payment amounts, or call history.6Federal Register. Protecting Consumers from SIM-Swap and Port-Out Fraud Carriers must also review and update their authentication procedures at least once a year.
The Free Account Lock
Every wireless carrier must let you lock your account so that no port-out request or SIM change goes through until you personally unlock it.6Federal Register. Protecting Consumers from SIM-Swap and Port-Out Fraud The carrier cannot charge for this feature, and the process to turn it on or off has to be simple enough that it doesn’t discourage use. If you haven’t enabled a port-out lock on your wireless account, that’s the single most effective step you can take. It takes a few minutes through your carrier’s app or customer service line.
Carriers can also lock your account on their own if they detect a high fraud risk, but they must notify you and let you unlock it when you make a legitimate request. Beyond the customer-facing lock, the FCC requires wireless providers to train employees specifically on recognizing fraudulent port-out attempts and handling fraud complaints.7eCFR. 47 CFR 52.37 – Number Portability Requirements for Wireless Providers These rules apply to all commercial mobile providers, including prepaid carriers and resellers. If a carrier fails to follow the rules and you lose your number to fraud, that failure strengthens any complaint you file with the FCC.
Passing the Number to Another Person
Transferring a number to a family member or someone else is different from porting. Porting moves your number to a new carrier under your name. A transfer changes who the number is assigned to, usually within the same carrier. The current account holder generally has to contact the carrier and authorize the change. The carrier will want the account in good standing with no unpaid balance, and the person taking over the number typically has to pass a credit check and accept full financial responsibility going forward.
When the Account Holder Dies
No federal law directly addresses what happens to a phone number when the account holder passes away. Each carrier sets its own policy, and the process usually involves contacting customer service with proof of death, such as a death certificate. Most major carriers will let a family member either close the account or transfer the number to a new account. Act quickly. An unpaid account will eventually be terminated, and once the carrier releases the number, it’s gone.
Two Boundaries Worth Knowing
Toll-free numbers are not an asset you can sell. If you run a business with an 800, 888, 877, 866, 855, 844, or 833 number, the FCC explicitly prohibits acquiring a toll-free number with the intent to resell it for a fee.8eCFR. 47 CFR 52.107 – Hoarding The agency also bans “warehousing,” where a carrier or its agent reserves toll-free numbers without an actual subscriber lined up. Routing multiple toll-free numbers to a single subscriber creates a presumption of hoarding, which can trigger penalties.9eCFR. 47 CFR Part 52 Subpart D – Toll Free Numbers You can still port a toll-free number between carriers, but if you’re closing a business and hoping to sell the number, federal law says you can’t.
Survivors of certain crimes have a separate right. The Safe Connections Act of 2022 lets survivors of domestic violence, stalking, sexual assault, and related crimes separate their line from a shared account, and account locks cannot be used to block a legitimate line-separation request.7eCFR. 47 CFR 52.37 – Number Portability Requirements for Wireless Providers The point of the law is to keep a shared wireless plan from being used as a tool of control over a survivor’s phone number.
The Practical Takeaway
You don’t own your phone number, but the rights you do have are workable for almost every situation. You can bring it to a new carrier, you can lock it against fraud at no cost, and you can hand it off to another person through the carrier. The gaps in your control are narrow but real. Let the account lapse and the number can be gone for good. Move across the country and you may not get to keep it. Hold a toll-free number and you can’t sell it. Treat your phone number less like something you own and more like something you maintain: keep the account active, turn on the port-out lock, and know how porting works before you need it.
