Transfer your number from Google Voice

What to find in the Google Admin console and keep before transferring your number to Callizy.

Role : ManagerDuration : 15 min

Before you start

  • In Canada, Google Voice goes through Google Workspace. You need the Google Voice Admin role in the Google Admin console.
  • For the account number: the right to manage billing (Billing management).
  • Keep Google Voice active until the transfer is complete.

Step by step

8 steps, about 15 min

Steps 1 to 6 are done in the Google Admin console. Menus are named as in its English version.

  1. 1

    In the Google console

    Write down the transfer PIN

    2 min

    Open Apps › Google Workspace › Google Voice › Number porting › Port-out info. Write down the code: it is the transfer PIN. Do not change it during a transfer: the request could be refused. The details are on Google’s help page.

  2. 2

    Write down the account number

    1 min

    Open Billing › Payment accounts. The account number is under Account ID. You need the right to manage billing.

  3. 3

    Note the customer name and the service address

    2 min

    The service address is that of the Voice account’s primary location: Google Voice › Locations. It is not the billing address, nor the address assigned to the number. In Canada, Google checks the customer name and the postal code of this address: write them in Callizy as they are at Google.

  4. 4

    Download your latest bill

    2 min

    Callizy asks for last month’s bill, showing the name, the address and the numbers. Download your latest Google bill.

  5. 5

    Export your contacts and history

    5 min

    Your contacts are in Google Contacts: select them all, then Export, in Google CSV format. History, text messages and voicemail messages: Google Takeout, Voice service.

  6. 6

    Keep Google Voice active until the transfer

    until transfer day

    Do not cancel Google Voice before Callizy confirms the transfer is complete: otherwise, the transfer could be refused. Do not change the Port-out info code either.

  7. 7

    In Callizy

    Do the transfer in Callizy

    20 min

    In the Administration space, open Numbers, then Transfer a number. In Carrier, write Google Voice. Enter the account number, the PIN from Port-out info, the customer name and the primary location’s address, add the bill, then sign the letter. Step by step: Transfer your current number to Callizy.

  8. 8

    At Google, at the end

    Cancel Google Voice once the transfer is complete

    5 min

    Callizy writes to you when the transfer is complete. Call your number from another phone: it should ring in Callizy. Only then, cancel Google Voice.

Key points

  • The service address is that of the Voice account’s primary location, not the billing address.
  • Do not change the Port-out info code during the transfer.
  • Do not cancel Google Voice before the transfer is complete.
