We provide this list for those who might be having difficulty tracking down the appropriate address to contact the insurance company in a traffic collision case. These companies are so big that finding where to send information can be a challenge.

These insurance company phone numbers are up to date as of 2025 and are especially useful if you are trying to report a claim, follow up on a case, or need to reach someone fast after an accident. You will also find physical mailing addresses in case you need to send proof of insurance, photographs, medical bills, or any other documentation.

This is only a partial list covering probably 90% of the insurance companies we have dealt with in tort cases. If you are a lawyer or a personal injury accident victim looking for an insurance company’s address, feel free to contact us, and one of our lawyers will provide you with the name of the insurance company.

You will note that there are often more than one address for each insurance company. Many insurance companies split their cases between more than one Maryland office. Often, one office handles the P.G. county cases and surrounding counties, and another office specializes in cases in Baltimore, etc.

If you need help with an insurance claim, us at 800-553-8082 or get free a online consultation.
