When you add or claim your profile, you can verify it through phone, text, email, or video. You may have to verify with more than one method. Available methods depend on business category, public info, region, support hours, and volumes.
Once you pick your verification type, Google has to review your verification. These reviews can take up to 5 business days, and help maintain the integrity of profiles. Once verified, you’ll receive a notification. If Google can’t verify your business using the first method, another “Get Verified” button will show up again in your account, and at that point you can try a different verification method.
After you verify, it can take up to a few weeks for your updated business information to show up across Google, but at this point you can begin to update information about your business.
