Support / Voice / Porting / Retrieving PINs

Retrieving account PINs for porting.

Most US carriers require a 4–6 digit account PIN (sometimes called a transfer PIN or port-out PIN) to verify identity before they release a number. An incorrect or missing PIN is one of the most common causes of port rejection. This guide covers how to retrieve or reset the PIN with each major US carrier.

Sign up Porting overview

Wireless carriers

Verizon Wireless

  • Sign in to My Verizon → Security → Account PIN to set or reset.
  • For a number-transfer PIN, dial #PORT from the line, or generate it inside the Verizon app.
  • Default PIN is often the last 4 digits of the account holder's SSN, or 0000.
  • Support: chat or phone via verizon.com/support.

T-Mobile

  • Use the T-Mobile app or website → Profile → T-Mobile ID → PIN/Passcode.
  • Default PIN may be the last 4 digits of the device IMEI.
  • If forgotten, call support or visit a store with photo ID.
  • Support: 1‑877‑746‑0909.

AT&T (including GoPhone)

  • Default PIN is often the last 4 digits of the phone number, or the explicit port-out PIN.
  • Log in to your online account to view the port-out section, or call support.
  • Support: 1‑800‑331‑0500.

U.S. Cellular

  • Default transfer PIN is often the last 4 digits of the phone number.
  • To get the official porting PIN, call 1‑800‑872‑4249.

Xfinity Mobile

  1. Sign in to your Xfinity Mobile account on the website or app.
  2. Open the Devices tab and select the line tied to the number you want to transfer.
  3. Scroll to Transfer your number or cancel this line and click Learn More.
  4. Choose an active line to receive a one-time passcode (OTP) by text.
  5. Enter the OTP and confirm — the transfer PIN is then sent by text.
  6. The PIN is valid for 24 hours and works for any line on that account.

If you can't retrieve the PIN online (typically because the account is missing a verified contact method), an Xfinity retail store visit with photo ID may be required.

Support: 1‑888‑936‑4968 — dedicated Xfinity Mobile line; can issue a transfer PIN or escalate if the app/website flow fails.

Landline / VoIP carriers

Comcast Voice (Xfinity Voice)

Comcast Voice uses a separate four-digit Home Phone Security PIN, which is required to authorize port-outs.

To view or reset it, sign in at xfinity.com → Account & Identity → Service Access → Home Phone Security PIN. You can view, change, or request a new PIN. If you've never set one up, you can request one by:

  • Email — typically delivered within ~2 hours.
  • Automated phone call — about 5 minutes.
  • Mail — 5 to 7 business days.

Comcast doesn't publish a standalone number for voice port-out requests; the new carrier (us, in your case) submits the port and Comcast processes it on the back end. For unresolved delays, your new provider can escalate.

Reported helpdesk: 1‑877‑397‑9734 — community-reported as an Xfinity phone-porting helpdesk that may route to specialized landline-port support.

Cox

Account number: on your billing statement, or in the Cox online account / mobile app. Cox support can also retrieve it: 1‑800‑234‑3993.

Port-out (transfer) PIN: printed on the first page of every Cox bill. You can also view or update it on the Cox website or mobile app.

  • Cox Mobile — both the account number and the port-out PIN are required to transfer a mobile number.
  • Cox Home Phone (landline) — porting is handled by your new carrier through Cox's internal platform (CPOSS). The new carrier requests the transfer using the account number and PIN. Cox does not initiate the port; keep service active until the port completes.

If you can't find or need a new PIN, Cox support may ask you to email cox.help@cox.com with your name, address, and any forum link so they can issue a port-out PIN.

Frontier

Account number: a 17-digit number found at the top of your bill or in the Frontier account portal.

Port-out PIN: typically the last four digits of the account number. If unsure, contact Frontier support to verify.

Timing: ports usually take 3 to 5 business days, sometimes faster. The new carrier initiates the port; Frontier doesn't start it. Don't cancel Frontier service before the port completes — early disconnect causes the port to fail.

Support contacts:

  • Main support / port-out assistance: 1‑800‑921‑8101.
  • Alternate customer service (24/7 per some sources): 1‑800‑921‑8104.
  • Automated billing / payment (requires 17-digit account number): 1‑800‑917‑7489.
  • Live chat / help center via the Frontier website or MyFrontier app.

Quick contact summary

General best practices

  • Have your identity verifiers ready: account number, last 4 of SSN, billing address, or IMEI.
  • Use the carrier's official website or app to reset or create the PIN — avoid third-party tools.
  • Some carriers won't reveal an existing PIN, only let you reset it. Plan for that round trip.
  • Don't cancel existing service until the port completes — early cancellation is the fastest way to lose the number.
  • Use a secure, non-obvious PIN. Birthdates and repeated digits are easy to guess.
  • Verify the BTN (billing telephone number) and service address against the carrier's records before submitting.
  • Some carriers offer a port-out freeze (sometimes called a Local Carrier Freeze). If active, it must be removed before the port can succeed.
  • If a port is rejected, request a Customer Service Record (CSR) directly from the losing carrier — it shows the carrier's exact account name, service address, BTN, and number list, and is the best document for resolving disputes.
