Fix issues with your number transfer to Fi

If you have problems transferring your number to Google Fi, use this article to help troubleshoot.

Troubleshoot "Couldn't transfer your number" error

If your number transfer doesn't go through, you should get a notification in the Google Fi app that tells you what to do.

When you get an error message, it’s often because of incorrect or incomplete account information. To update your information, follow the instructions in the error message.

To make sure you provided the correct information, check with your carrier.

Information that may show up as an error:

  • Typos
  • Incorrect account numbers or PIN
  • Account numbers with dashes
    • Tip: Try to enter your account number without any dashes.
  • Incorrect zip codes

You can check with your last carrier for the most recent info.
