#Verify a business listing by mail#
To verify your business listing by mail, enter your business address in Google My Business. We’ll send you a #POSTCARD# with a verification code. Most postcards arrive within 14 days. Before requesting to verify your listing by mail, make sure your business address complies with our address entry guidelines.

If your business is eligible to get a verification code by phone, you'll see the Verify by phone option when you request verification. If you don't see it, verify your listing by mail instead.
