Google has now added the Webmaster Tools Verification for Google My Business. This was announced by Google’s Jade Wang in the Google forums. She explained that from now on, if you have verified a page for your business, you may be verified on Google My Business instantly. This is only possible if your website is already verified with Google Webmaster Tools.
You need to use the same account to sign in to Google My Business that you used for your site verification with Webmaster Tools. One thing that needs to be noted is that not all the business categories are be eligible for instant verification. Thus, all businesses that have their websites verified with Google Webmaster Tools will not be verified instantly. If that is the case you can use one of Google’s other methods for verification.
