Google Fi Account Number & PIN: Accurate 2026

How to get your Google Fi account number and transfer PIN from the Get Transfer Info screen, the 14-day expiry, and the two Fi-specific settings that silently kill a port-out.

Last updated October 3, 2026

Here is how to get your Google Fi account number and transfer PIN, and what to do with them when you move your number to another carrier.

Account Number

In the Google Fi app or at fi.google.com: Account → Manage plan → scroll to Leave Google Fi → Transfer your number to another carrier → Get Transfer Info. The account number and the PIN are on the same screen.

Transfer PIN

Generated on that same Get Transfer Info screen. It expires 14 days after you request it, and Google states the information is case-sensitive.

Do not pause your Google Fi service during a transfer. Google says it outright: pausing during a number transfer causes the port-out to fail. Fi actively markets pausing as the polite alternative to cancelling, which is exactly why this catches people. Leave the line running until the number has moved.

How to get your Google Fi account number and transfer PIN

Both come from the same screen, and you reach it through the cancellation flow – which does not actually cancel anything.

  1. Turn off Number Lock first. At fi.google.com: Phone settings → Privacy & security → Sign in to manage Number lock → re-authenticate → toggle it off. With Number Lock on, you cannot port your number to another carrier at all.
  2. Open the Google Fi app or go to fi.google.com/account.
  3. Go to Account → Manage plan.
  4. Scroll to Leave Google Fi and choose Transfer your number to another carrier.
  5. Under the cancellation-pending banner, tap Get Transfer Info. Your account number appears here, with a button to generate the transfer PIN.
  6. Copy both exactly. Google states the information is case-sensitive, and the name and address you give the new carrier must match what Fi has on file.

Before you start the transfer

  1. Starting the cancellation flow does not cancel your service. Google is explicit: Fi stays active until your number successfully transfers.
  2. Never pause the line. Pausing during a transfer fails the port.
  3. Do not lose access to your Google Account. Google states that if Number Lock is on and you lose access to the Google Account, Fi cannot provide your port-out parameters at all. There is no workaround.
  4. Use the PIN within 14 days. If it goes unused past that, repeat the Get Transfer Info steps for a new one.

Formerly Project Fi. Google renamed the service in November 2018. If the account predates the rename, see Project Fi for the history and what changed.

Check coverage before you port

Google Fi runs on the T-Mobile network, so the coverage you get at your address is T-Mobile coverage. Check it on T-Mobile’s own coverage map before you start the transfer.

Your right to keep the number is federal, not a carrier policy. The rule is the FCC’s: Portability: Keeping Your Phone Number When Changing Service Providers.

Google Fi and Google Fi file under one FCC registration

Google Fi is operated by Google North America Inc. of California, which has filed with the FCC under the same registration since 2015 — 11 years. The same registration also covers Google Fi. The support line on file with the FCC, 1-844-825-5234, matches the number published above. Checked September 22, 2026 against the FCC Form 499 filer database.

Same towers, different price

Google Fi runs on T-Mobile’s network

Google’s own coverage page says Fi provides nationwide 4G LTE and 5G through the T-Mobile network. Older write-ups describing Fi as a three-network service are out of date – T-Mobile is the only carrier Google names today.

Common questions about leaving Google Fi Wireless

What towers does Google Fi use?

T-Mobile towers. Google’s own coverage page states that Google Fi Wireless provides nationwide 4G LTE and 5G coverage through the T-Mobile network. Some Google device pages still carry legacy “multiple networks” wording, but T-Mobile is the only carrier Google names anywhere now, and US Cellular – historically Fi’s second LTE partner – was absorbed by T-Mobile in August 2025.

What network does Google Fi use?

T-Mobile. Treat any surviving multi-network claim as old marketing copy rather than a description of today’s service.

How long is a Google Fi transfer PIN good for?

Fourteen days. Google states that an unused transfer PIN expires after 14 days; generate a new one by repeating the Get Transfer Info steps.

Why did my Google Fi port-out get rejected?

Four Fi-specific causes: Number Lock was still switched on, the service was paused during the transfer, the account number or PIN was typed with the wrong capitalization because the values are case-sensitive, or the name and address given to the new carrier did not match what Google has on file.

Does Google Fi have a customer service phone number?

Yes – 1-844-825-5234, published on Google’s own Fi support and FAQ pages. Google does not publish hours. Chat and callback through the Fi app are usually faster.

Do I have to cancel Google Fi before switching?

No. You go through the cancellation screen to reach the transfer information, but Google states the service stays active until the number transfers. Do not pause it either.
