Called Verizon on a Sunday afternoon trying to port a number to a new carrier, only to get bounced back with “PIN doesn’t match” three times in a row. Turned out Number Lock was quietly turned on for over a year with zero memory of enabling it. Had to dig through security settings, turn it off, generate a fresh PIN, and start over. Ten minutes turned into an hour.
Porting a number in 2026 is faster than it used to be, but the failure points haven’t gone away, they’ve just moved. Here’s the actual checklist.
The One Rule That Matters Most: Never Cancel Your Old Service First
Canceling service before the port completes releases the number back into the pool, and reclaiming it afterward is not guaranteed. The port itself automatically closes the old account once it completes.
Starting a port today? Don’t touch the cancel button on the old account at any point.
How to Get a Transfer PIN from Each Major Carrier
| Carrier | How to Get the PIN | Valid For |
|---|---|---|
| Verizon | My Verizon app, or dial *#PORT | 7 days |
| T-Mobile | Dial #PORT, or T-Mobile app | Varies |
| AT&T | att.com account settings | 7 days |
| Mint Mobile | Mint app account section | Varies |

Get the PIN right before starting the port, not days in advance — several carriers expire it if unused too long.
Before You Start: Check Three Things
Is the phone unlocked? If financed through the carrier, it might still be locked. Postpaid carriers are required by FCC rules to unlock a device active for at least 60 days.
Is a security lock enabled? Verizon’s Number Lock and similar features on other carriers block unauthorized transfers by default — inconvenient for the account owner too. Check before starting, not after the first rejection.
Does the new carrier work where you live? Worth checking before committing.
eSIM Complicates Things Slightly
Most recent phones activate via eSIM — a QR code or tap-to-install link, no physical SIM needed. A phone can hold multiple eSIM profiles but only one is active at a time; switching is a toggle in Settings, no carrier re-activation needed.
Ended up with three eSIM profiles stacked on one phone after a couple of carrier tests last year — old personal line, a work line, and a leftover test SIM from a review unit. Texted a client back from what turned out to be the wrong profile entirely, and didn’t notice until they replied confused about the different number showing up. Took a minute of digging through Settings → Cellular to figure out which toggle was actually active before switching back and sending an apology text from the right line.
Running more than one eSIM profile on the same phone? Check which one is active before sending anything that matters — the switch is silent and easy to miss.
What to Test After the Port
Most ports complete in 15 minutes to a few hours. Once done: test call, test text, speed test, confirm 5G shows correctly, and check visual voicemail.
Port just completed? Test call, test text, speed test — in that order.
Watch Out for Unauthorized Port-Out Scams
A scammer with enough personal info can attempt to port a number away without the owner knowing — used to intercept account verification texts. Carriers send a confirmation text for any port request; if one arrives unprompted, call the number in that message immediately.
A family member got exactly this text out of nowhere last year — “Your number transfer has started” — despite not requesting anything. Panic first, then a call to the number listed in the message, which turned out to connect straight to the carrier’s fraud line. The attempted port got blocked before it went through, but the ten minutes between reading that text and getting someone on the phone were genuinely stressful, mostly from not knowing yet whether it was already too late.
Get a port confirmation text you didn’t request? Call the number in the message immediately — don’t wait to see if it resolves on its own.

Frequently Asked Questions
Should I cancel my old carrier before porting?
No. The port automatically closes the old account. Canceling first can release the number permanently.
How long does porting take?
Most complete in 15 minutes to a few hours. Cross-network transfers occasionally take up to 24 hours.
Why did my port get rejected?
Usually the PIN, account number, or billing ZIP doesn’t match, or a security lock is still enabled.
Does porting cost anything?
No — free at all major US carriers under FCC rules.
