Things to Remember...

  • Granite Insurance Company is a subsidiary of American Insurance Group (AIG)
  • Granite State most likely provides commercial insurance rather than personal
  • Granite State does not have its own website, so information about the company is scarce

Granite State Insurance Company Products

It is unclear exactly what types of insurance products Granite State actually sells. Again, because it doesn’t maintain its own web presence, it’s difficult to find this information.

But the information we were able to uncover indicates that Granite State is most likely involved in commercial lines insurance rather than personal insurance.

If our assumptions are right, Granite State probably writes business policies for the following:

  • general liability
  • property liability
  • professional liability
  • umbrella
  • workers compensation

These would be the typical products offered by a standard commercial insurer. You can find all Granite State’s products listed on the AIG website.

Granite State Insurance Company Agents

It is not clear whether or not Granite State utilizes independent agents. We do know that AIG works with local agents because it provides an agent locator tool on its website.

The only problem with this tool is that it produces very limited results.

Using a ZIP code from a typical mid-sized American city as a test, the agent locator tool produced no results.

Granite State Insurance Company Careers

It’s difficult to say whether or not Granite State Insurance Company is hiring at this time.

The AIG website makes no mention of Granite State in its careers section. However, it does provide a searchable job listings database for all positions, both in the United States and around the world.

One of the unique features of its job search is that searches can be conducted by individuals looking for work or agents working as recruiters.

If Granite State is indeed hiring, it is possible they are doing so through the AIG human resources department. You may also find Granite State job listings on various industry-specific websites.
