Porting to Gigs from a US carrier — full carrier reference

Last updated: June 5, 2026

This article is the detailed carrier-by-carrier reference for porting your number to Gigs in the United States. For the shorter overview, see How do I port my number in? — United States. Carrier porting policies change frequently — if you see something different on the carrier's own page, trust the carrier's current page and let us know.

Each carrier has its own way of giving you two pieces of information you'll always need to port your number to Gigs: your account number with the current carrier, and a valid Number Transfer PIN (NTP). You may also need the billing ZIP code and the exact name on the account.

Do not cancel your current service before the port completes. Cancelling first will release your number back into the pool and you may lose it. Your old carrier automatically closes the line once Gigs completes the port-in.

AT&T Postpaid

  • Account number: myAT&T → Profile → Sign-in info → My linked accounts. Also on the top right of any paper or PDF bill, or by calling 1-800-331-0500.
  • Transfer PIN: dial *PORT (*7678) from your AT&T phone (the PIN is sent by text), or go to myAT&T → Profile → People & Permissions → Wireless → Transfer phone number → Request a new PIN. Only the primary online user (typically the account owner) can request the NTP. Valid 4 days on consumer accounts, 14 days on business accounts. One PIN covers every line on the account.
  • Device unlock: required to bring your AT&T phone to Gigs. AT&T requires 60 days active on AT&T, the installment plan paid in full, and the account in good standing. Cancelling service makes any remaining installment balance due on the final bill and stops promotional bill credits.

AT&T Prepaid

  • Account number: dial 611 from your AT&T Prepaid phone or call 1-800-901-9878, or check your activation confirmation email.
  • Transfer PIN: AT&T Prepaid doesn't issue a separate NTP. Most carriers accept your 4-digit account passcode (set at activation). If a 6-digit code is required, call 1-800-901-9878 and ask them to set a port-out PIN.

T-Mobile Postpaid

  • Account number: sign in at T-Mobile.com or the T-Life app → Account. The 9-digit account number is at the top. Alternatives: top right of your bill, or call 1-800-937-8997.
  • Transfer PIN: only the Primary Account Holder can generate it. In the T-Life app on the T-Mobile network (Wi-Fi off): Manage → gear icon → Permissions & controls → Transfer PIN. Same path on T-Mobile.com from a mobile browser on the T-Mobile network. Or call 1-800-937-8997. PIN is 6 digits, valid 7 days. If Port Out Protection is enabled on the line, disable it first.
  • Device unlock: T-Mobile requires 40 days active on T-Mobile, all device payments satisfied, and the account in good standing. Cancelling service makes remaining device balances due. For EIPs created on or after July 1, 2024, paying off early — including a forced payoff at port-out — also forfeits any remaining promotional bill credits.

T-Mobile Prepaid

  • Account number: usually your 11-digit phone number (country code 1 + 10-digit mobile). Or sign in to T-Mobile.com → My Account, top of the magenta bar. Or call 1-800-937-8997.
  • Transfer PIN: sign in to T-Mobile.com → My T-Mobile → My Profile → Transfer PIN, or call 1-800-937-8997 or 611. PIN validity is generally 4–7 days depending on how it was issued.

Verizon Postpaid

  • Account number: My Verizon → Account → Account Settings → Account Settings Overview, top under My Profile. Also in the Verizon app under Account → Edit profile & settings, on your bill top right, or by calling 1-800-837-4966.
  • Transfer PIN: only Account Owner or Account Manager can generate it. Standard Account Members cannot. Dial #PORT (#7678) from the Verizon line you wish to port, or in the Verizon app: Account → Edit profile & settings → Number Transfer PIN → Generate PIN. PIN valid 7 days; up to 5 PINs per line per day. Number Lock must be disabled on the line before the PIN works.
  • Device unlock (major 2026 policy change): Verizon's previous 60-day auto-unlock is gone for devices activated on or after January 27, 2026. New devices stay locked until the financing balance is paid in full. Paying off at a Verizon corporate store with a chip card, contactless pay, or cash unlocks immediately. Verizon Gift Card payoff adds a 35-day verification delay. Devices activated before January 27, 2026 keep the old auto-unlock policy.
  • Balance and bill credits: per Verizon, "If you disconnect a mobile number that has an active device payment agreement, the remaining balance of that agreement is due on your next bill." Promotional bill credits stop when the line disconnects.

Verizon Prepaid

  • Account number: My Verizon Prepaid → Profile & Settings → Display My Prepaid Account Number. Typically 10-digit mobile number followed by -00001. Or call 1-888-294-6804.
  • Transfer PIN: your 4-digit Verizon Prepaid Account Security PIN serves as the NTP. Reset it via Profile & Settings → Security → Manage Account PIN, or call 1-888-294-6804.
  • Device unlock (major 2026 policy change): Verizon Prepaid devices activated on or after January 27, 2026 require 365 days of paid, active service before they can be unlocked, and the unlock must be requested. If service lapses, the 365-day counter pauses and resumes when service is restored. Earlier devices keep the old 60-day auto-unlock.

Verizon-owned prepaid brands (Visible, Total Wireless, Straight Talk, Tracfone, Simple Mobile, Walmart Family Mobile)

Effective January 20, 2026, all of Verizon's value/prepaid brands moved to a 365-day device lock for newly activated devices. Phones purchased on or after that date are not eligible for unlock until 365 days of paid, active service have completed, and the unlock must be requested. Earlier devices keep the previous 60-day auto-unlock policy.
