Google announced they now support improved schema markup, rich snippets, for location pages.
Business Phone Support Schema
Google said they now support showing business telephone numbers for customer service, technical support, billing support, and bill payment. For each phone number you markup, you can specify if it is toll-free, suitable for the hearing-impaired, and whether the number is global or serves specific countries. Technically, you can specify more than those four categories but Google only will display those in the rich snippets. Google has added more details over here.
Hours Of Operation
On your business website’s contact us or branch locator page, you can now include additional markup to address of the business, the phone number, opening hours, and other information. You can even break it out by services or departments, which may be available at the business locations.
Here is a screen shot that shows the data Google may display in the rich snippets, after you add the schema to your site:
