How does Google Local work?
Each business listing in the Google Maps directory is in fact a 'cluster' of information Google derived from several different online places, such as the Yellow Pages.
The information that you submit through the Local Business Center however, is the information that Google will trust the most and list above all other providers' information. This means that your provided information will appear instead of the information gathered elsewhere.
To ensure the information you submit is accurate, Google will want you to verify the listing first, by contacting you at your business phone number.

The Local Business Center gives you the most control over the way your business listing appears in Google Maps. When you submit and verify info through the Local Business Center, you are providing the most authoritative info for your business listing.
