InsuredBetter's Overall Atlantic Casualty Insurance Company Insurance Score

3.5 Stars 2 Stars

We award Atlantic Casualty Insurance Company a final rating of 2 out of 5 stars. Though the carrier has high ratings by AM Best and the BBB, they are not BBB accredited. The insurance company has much more limited contact options than many other modern carriers do.

What we find most disappointing, however, are the disturbingly negative customer reviews across the map. There are many reports of canceled coverage after filing one claim, or not having been provided with clear coverage details from the start. 

So, overall we're forced to recommend looking into other insurance companies with the help of your independent insurance agent, and skip looking into ACIC. Especially if excellent customer service and reliable coverage promises are important to you.

Atlantic Casualty Insurance Company Pros and Cons:
