Your local SSA service center

As your local Social Security service center, the Union office supports 33,770 beneficiaries. While the majority of the local population consists of retirees, the 4,945 disabled workers served here represent 15% of the total. This office is responsible for distributing $59 million in monthly benefits, totaling $714 million annually across the region. Whether you are applying for the first time or managing existing benefits, understanding your local office's role is the first step in your journey.

At the Union office, you can file initial SSDI applications, drop off medical documentation, verify your identity, and update your direct deposit information. Please note that this office does not make final disability determinations, as those decisions are handled by the state DDS. Additionally, any necessary hearings are conducted at a separate Office of Hearings Operations location. You should schedule an appointment in advance to minimize your wait time.

Before you visit

To prepare for your appointment, bring a valid government-issued photo ID and a complete 15-year work history including dates and job duties. You should also provide a comprehensive list of your treating providers with their full addresses, recent medical records, and a current list of all medications. If you have received any prior denial notices, bring those documents as well. Expect your interview with a claims representative to last between 45 and 90 minutes. An attorney can help you prepare these documents to ensure your application is complete.

You may experience delays by submitting incomplete work histories or failing to provide the most recent medical records from your primary care physicians. Another frequent error is omitting information regarding mental health conditions, which are just as critical as physical impairments for your claim. Avoid signing any forms until you have read them thoroughly and understand exactly what information you are providing to the Social Security Administration.

Should you bring an attorney?

Even at the initial application stage, the evidence you gather and the way you present your case form the foundation for any potential appeals. If you apply without professional guidance, you may find the process overwhelming and face unnecessary denials. An attorney can help you organize your medical evidence and ensure your application accurately reflects the severity of your condition.

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 Union. The Union field office holds your file at every appeal stage, but the substantive decisions happen further up the chain.
