You can visit the Hattiesburg office for initial SSDI applications, document drop-offs, and in-person ID verification. While this office handles the intake of your paperwork, it does not decide the outcome of your claim, as that responsibility lies with the state DDS. Additionally, this office does not conduct hearings, which are managed at a separate location. You should schedule an appointment in advance to ensure a claims representative is available to assist you.

Before you visit

Bring a valid government-issued photo ID and a detailed work history to your appointment. You should also provide a comprehensive list of all treating providers with their contact information, recent medical records, and a current list of your medications. If you have received any prior denial letters, bring those documents as well. Expect your interview with a claims representative to last between 45 and 90 minutes.

Avoid pitfalls such as providing an incomplete work history or failing to include recent medical records from all your treating physicians. You should also document mental-health conditions alongside physical impairments. Never sign any forms at the office without reading them thoroughly to ensure all information is accurate. These oversights often lead to unnecessary delays in the processing of your application.

Should you bring an attorney?

The application stage is the foundation of your entire disability case, and the evidence you provide now will define your record if an appeal becomes necessary. Most people who apply without professional guidance face significant hurdles after an initial denial. An attorney can help you organize your evidence and ensure your application is as complete as possible from the start.

If your SSDI claim moves to a hearing

About two-thirds of initial SSDI applications nationwide are denied. If yours is, your case moves to a hearing before an Administrative Law Judge at one of the regional hearing offices that handles appeals from Hattiesburg. The Hattiesburg field office holds your file at every appeal stage, but the substantive decisions happen further up the chain.
