What Is Best Cellular?

Last reviewed October 25, 2026

Best Cellular (BestCellular.com) is a free, independent reference for US wireless carriers. It publishes the account number, transfer PIN and port-out steps for every US carrier and MVNO, active or shut down, and shows which of the three national networks each one runs on.

What does it do?

It answers one question: what do I need from my old carrier to move my number? For each carrier it lists where to find the account number, how to get the transfer PIN and how to port out. It also names the host network behind each brand, so you know whether a carrier runs on Verizon, T-Mobile or AT&T.

Who uses it?

Retail wireless stores, prepaid dealers and cellphone repair shops use it to move customers fast. Consumers use it when they switch carriers and the old one will not hand over a PIN.

Is Best Cellular a wireless carrier?

No. The site does not sell wireless service, activate phones or operate stores. To buy service, pick a provider from the carrier directory and sign up with that provider directly.

Does it cover carriers that have shut down?

Yes. Shut-down brands keep their own pages, so you can see what happened to the carrier and where your number can go.

Who runs Best Cellular?

Assertive Holdings, LLC owns and operates the site. M. Curtis McCoy manages its research, data and publishing. Read more on the About page.

What is the difference between Best Cellular and BestCellular.com?

None. Best Cellular is the brand. BestCellular.com is its only website. The domain was registered in 1998.

How do I move my number with it?

1. Find your current carrier in the carrier directory or the search box on the homepage.
2. Open its page and follow the steps for your account number and transfer PIN.
3. Give both to your new carrier. Keep your old service active until the transfer finishes.

Your account number and transfer PIN are two different things. Neither is your phone number, and most carriers print neither on your bill. The transfer PIN lookup shows where each carrier hides them. For the rules behind number porting, see the FCC guide to keeping your phone number.

What information does it publish?

Every carrier page covers the same core facts: where the account number lives, the transfer PIN method, port-out steps, the host network and the current status. Defunct brands get the same treatment, with a note on what happened and what to do with a number that still sits there. Tools such as the phone unlock checker cover the next step after a switch.

How does the site keep its data accurate?

Each carrier page carries a verified date. Carrier policies are checked against the carrier’s own help pages and support channels, and pages are corrected when a carrier changes its process. The site has published carrier data since 2010.

Why does this reference exist?

Carriers make leaving harder than joining. Many hide the transfer PIN, bury the account number and change their process without notice. This reference collects those steps in one place, keeps them current and publishes them for free, so store staff and customers stop guessing and start porting.

How do I contact Best Cellular?

Use the About page for company details. Carrier press teams can send corrections or new carrier information the same way.
