To change your business address and phone number:

1. Sign in to the Google Admin console. 
2. Do one of the following:
   • In the classic Admin console, click Domain Settings > Subscriptions & Billing > Access billing account.
   • In the new Admin console, click Billing > Access billing account.
     ^{Where is it? Which Admin console do I have?}
    .
3. Click Billing profile on the left-hand side of the page.
4. Click Edit and update your information.
5. Click Save.

A few notes:

• Once the billing profile for your Google account is initially set up, you will not be able to change the billing country for the account. The option to change other parts of the billing address will be available for the duration of your subscription.
• Learn about the difference between your business address and a billing address.
