Using Google Store Locator module you can solve your query.


  This project uses Google's Store Locator Utility Library and Google
  Maps to create a 'Store Locator' page that your site visitors can use
  to find and get directions to one of your physical stores. It was born
  out of a need for a simple to install and easy to use locator feature
  for Drupal 7. This module is different from other 'locator' type
  modules (e.g. OpenLayers Locator) in that it doesn't require you to
  have any knowledge of it's dependant modules, and it allows developers
  to focus on implementing personal customizations quickly because the
  installation process is so light.
