Everyone should check to see if their business is listed correctly on Google. To find out, visit Google Local or Google Maps and search for your business. If you find anything you'd like to change, you can add or update your business information at the Google Local Business Center. This way, when someone's looking for you on Google Local or Google Maps, they'll be able to get accurate, up-to-date information.
And an important note: Google Local listings and AdWords display separate business information, so you should review your Google Local listing even if you know your AdWords account information is correct.
