Moving from a mobile carrier

If customers call and text your business on a cell phone number from AT&T, Verizon or T-Mobile, you can move that number to Chargezen so the whole team, and Concierge, can answer it. Each carrier gives you a transfer PIN and has a lock to turn off first.

Run the number through Chargezen's check first. If it says "Only toll-free and local numbers can be moved.", that number can't come to Chargezen. Cell numbers are 10-digit numbers, so they need the 10DLC registration below before they move.

Chargezen moves US (+1) local and toll-free numbers that can send texts. Short codes (5 or 6 digits) can't move. A local number needs an approved 10DLC registration in Chargezen first, so it can text the moment it arrives. Type the number into Bring your number and Chargezen tells you whether it can move, and why not if it can't, before you fill in anything else.

Moving the number ends it on that phone. Verizon, for example, says the new carrier moves the number and disconnects the line. Plan for the phone to stop taking calls and texts on that number from the port date.

For every carrier you need the account number (it's on your bill) and the account holder's name and billing address exactly as the bill shows them, plus a recent bill as a PDF. Then get the carrier's transfer PIN. A PIN expires after a few days, so get it right before you submit the move in Chargezen.

AT&T

From AT&T's Get a PIN to transfer your wireless number (checked October 18, 2026):

• Sign in, go to your account settings, scroll to Transfer phone number and select Request new PIN. Business primary users can also contact AT&T, and a rep emails the PIN.
• The PIN expires 4 days after you request it (14 days for business accounts), and it's the same for every number on the account.
• If Wireless Account Lock is on, you can't transfer the number. Turn it off first.
• Don't disconnect your AT&T service before asking the new provider to move the number.

Verizon

From Verizon's port-out FAQs and, for business accounts, Port out my number (both checked October 18, 2026):

• Consumer accounts: dial #PORT from the phone with the number, or generate the Number Transfer PIN in the My Verizon app or website.
• Business accounts: in My Business, open the line and go to Line Overview > Device Information > Number Transfer PIN > Generate PIN. Each line has its own PIN.
• The Number Transfer PIN expires after 7 days. You need it and your Verizon account number.
• Turn off Number Lock before moving the number.

T-Mobile

From T-Mobile's Transfer your phone number and, for business accounts, Change or transfer your number: Account Hub (both checked October 18, 2026):

• The Primary Account Holder turns off Port Out Protection on the line, if it's on, and generates a Temporary Port Out PIN for the line.
• Business accounts: in Account Hub, on the Manage Lines tab, select the three dots for the line and choose Generate transfer PIN.
• You need your T-Mobile account number (on your account or bill), the Temporary Port Out PIN and your account PIN or passcode.

When you submit the move, you pick a port date at least 5 business days out. Chargezen books the earliest date the carriers allow on or after it, and the confirmed date (the FOC date) shows on the number's row under SMS numbers. Carriers set the exact time.

• Toll-free numbers: texting usually moves about 3 business days after you confirm the code, before the port date. The row shows Texting live. On the port date, calls move too.
• Local numbers: calls and texts move together on the port date, and the number joins your approved 10DLC campaign.
• When the move is finished, the row shows Moved. If you chose Concierge answers calls, the number is ready in Chargezen Voice for you to activate.
• If the move is sent back, the row shows Needs attention with the reason. Click Fix, correct the step it opens and click Resubmit move.

In Chargezen, go to Concierge > Deploy > Channels, click Chargezen SMS and, under SMS numbers, click Bring your number. Here is what to enter from your carrier at each step. The full walkthrough is in Bring your number.
