How to Transfer a Phone Number (2026 Step-by-Step Guide)

To transfer a phone number in the US, you submit five fields to your destination carrier — the full 10-digit number, the account number from the losing carrier, the account-holder name on record, the billing zip code, and a one-time Number Transfer PIN — and your destination carrier (AT&T, Verizon, T-Mobile, Google Voice, Visible, RingCentral, Cricket, Boost, US Cellular, or any other major US carrier) processes the port-in onto your existing line, typically within 24–48 hours for wireless-to-wireless transfers under FCC Local Number Portability rules (47 CFR Part 52).

That transfer process applies equally whether the number is the one you currently have at your old carrier, number you bought outright from Digit Exclusive, or number that has been parked on a transitional carrier while you finalize a brand launch. The destination carrier doesn't distinguish — it just runs the standard port-in procedure on whatever 10-digit US phone number you authorize them to receive.

The five fields every carrier transfer needs

About 90% of phone number transfer rejections trace back to one of these five fields not matching the losing carrier's record. Get all five right at submission time and most ports complete on the first attempt:

  1. The full 10-digit phone number. No country code, no extension, no formatting. Just the ten digits.
  2. The full account number from the losing carrier. The most-commonly-wrong field. Carriers expect the entire account number, not just the last four digits and not the phone number itself. Verizon Wireless: "Account Number" on the bill. Spectrum Mobile: account number begins with letters. Cricket/Boost: numeric account number in the app under Account > Manage Account. Google Voice: AT&T and other carriers accept the Google Voice account email as the account-number equivalent.
  3. Account-holder name and billing zip, character-for-character. If the losing carrier has "ACME LANDSCAPING INC" in caps, don't type "Acme Landscaping, Inc." — punctuation, suffixes, middle initials all need to match. The billing zip is the zip on the losing carrier's account, not necessarily where you live.
  4. Number Transfer PIN from the losing carrier. Since 2022 the FCC has required all major US wireless carriers to issue a one-time Number Transfer PIN on demand. Verizon issues it through My Verizon under Account > Number Transfer PIN. T-Mobile via the My T-Mobile app or by texting NTP to 7678. Cricket, Boost, Visible, and US Cellular expose it in their mobile apps. AT&T uses the myAT&T app under Profile > Account Information > Wireless Passcode/Number Transfer PIN. Each carrier's PIN is valid 7 days; generate it close to the moment you submit the port, not weeks in advance.
  5. The destination carrier's account information. If you're activating a new line on AT&T, the port happens as part of the new-line setup. If you're porting onto an existing line, the destination carrier will already have your account details — you just authorize the inbound transfer.

How long does it take to transfer a phone number

Wireless-to-wireless ports where every field matches on the first try typically complete in 1 to 24 hours. Some clear in under an hour. Several factors push the timeline longer:

  • VoIP-source ports (Google Voice → AT&T, RingCentral → Verizon, OpenPhone → T-Mobile) often take 2–5 business days because the releasing system runs on different infrastructure than retail wireless.
  • Business multi-line ports (AT&T Business, Verizon Business) require a signed Letter of Authorization (LOA) on company letterhead, an EIN match, and a separate intake. Plan 3–7 business days.
  • Field corrections. If the destination carrier flags a mismatch, the port pauses until you fix the field at the losing carrier. Each correction adds 24–72 hours.
  • Numbers held under 30 days at the current carrier sometimes face extra fraud-flag verification because rapid-cycle porting is a SIM-swap-fraud indicator.

The one mistake that breaks transfers

Do not cancel the line at the losing carrier before the destination carrier confirms the port has completed. This is the single most expensive mistake first-time porters make. If you cancel the old line before the destination carrier sends the completion notification, the number can fall out of porting eligibility — the losing carrier may release it back to the available-inventory pool, where it can be assigned to another customer. Recovering number from that state is sometimes possible through escalation and sometimes not.

Right sequence:

  1. Submit the transfer.
  2. Wait for confirmation from the destination carrier.
  3. Place a successful test call from a non-destination carrier line (borrow a friend's Verizon if porting to AT&T).
  4. Then cancel the losing carrier service.

Transfer phone number when buying from Digit Exclusive

If you purchased a vanity phone number from Digit Exclusive, the transfer process is the same — you receive a transfer kit by email containing all five fields formatted for any major US carrier to accept. The kit includes:

  • The full 10-digit number you purchased.
  • The account number on the parking carrier where the number is currently held.
  • The account-holder name and billing zip on the parking-carrier record.
  • A valid Number Transfer PIN good for 7 days from kit issue.
  • The losing-carrier identification AT&T / Verizon / T-Mobile needs to route the port request correctly.

You submit that kit to your destination carrier through the standard port-in channel (myAT&T app, My Verizon, T-Mobile app, Google Voice settings, Visible app, etc.) and the carrier handles the port-in. Digit Exclusive doesn't touch your destination-carrier account — we provide the documentation; your carrier provides the wireless service.

Transfer phone number — FCC consumer rights

Under FCC 47 CFR Part 52 (Wireless Local Number Portability), every US consumer has the federal right to transfer their phone number between carriers when changing service. Carriers cannot block ports based on unpaid bills (those become collections issues, not port-blockers), cannot charge for port-in (port-outs may have small fees on some prepaid carriers), and must process valid port requests within FCC-mandated timelines.

The FCC consumer guide at fcc.gov/consumers/guides/keeping-your-phone-number-when-changing-service-providers spells out the rules in plain language. Highlights:

  • You have the right to keep your phone number when switching carriers, period.
  • Outstanding bills do not prevent porting (they remain owed to the original carrier as a separate matter).
  • Carriers cannot require you to "release" the number before porting — submitting the transfer request IS the release.
  • Wireless-to-wireless transfers must complete within timelines set by the NPAC industry body, typically 1–24 hours.

Frequently asked questions about phone number transfer

Can I transfer a phone number to a different carrier?

Yes. Federal FCC Local Number Portability rules guarantee you the right to transfer your number when changing carriers. Wireless ports typically complete in 1–24 hours when all five required fields match on submission.

How do I get my Number Transfer PIN from my current carrier?

Verizon: My Verizon app under Account > Number Transfer PIN. T-Mobile: My T-Mobile app or text NTP to 7678. AT&T: myAT&T app under Profile > Account Information > Wireless Passcode/Number Transfer PIN. Cricket / Boost / Visible / US Cellular: each has its own mobile app option. PIN is valid 7 days.

What if my phone number transfer is rejected?

Rejection almost always points to a single field mismatch — usually account number, account holder name, or expired Transfer PIN. Call your destination carrier's port support line for the rejection reason, fix the field at the losing carrier, and resubmit. Most ports clear on the second attempt within 24–72 hours.

Can I transfer a vanity phone number I bought from Digit Exclusive?

Yes. Vanity numbers purchased from Digit Exclusive are real local US phone numbers held on a transitional parking carrier until you port them. The transfer kit you receive after purchase contains all five required fields formatted for any US carrier to accept.

How long should I keep the old line active during transfer?

Keep the old line active until the destination carrier confirms the port has completed AND you have placed a successful test call. Do not cancel before completion — canceling early can drop the number out of porting eligibility and risk losing it back to the carrier's available-inventory pool.

Does it cost anything to transfer a phone number?

The destination carrier does not charge a port-in fee for standard wireless ports as of 2026. The losing carrier may charge a final-bill remainder or early-termination fee if you're on device financing or a contract — that fee comes from the losing carrier as a billing matter, not from the destination carrier as a port fee.
