Address, phone & hours

Your local SSA service center

As your local Social Security service center, Hillside manages a diverse portfolio of benefits for the community. While the office supports 49,965 total beneficiaries, the caseload is primarily retirement-focused, with 76% of recipients being retired workers. Only 11% of the individuals served here are disabled-worker beneficiaries, making this a retirement-heavy catchment area. Despite the lower share of SSDI recipients, the office facilitates $90 million in monthly payments to support local residents.

You can visit Hillside to file your initial SSDI application, drop off required medical documentation, or verify your identity in person. This office also assists with Medicare enrollment and setting up direct deposit for your benefit payments. Please note that this location does not make the final decision on your disability claim, as that process is handled by the state DDS. Additionally, any necessary hearings for your case will be conducted at a separate office location.

Before you visit

To ensure your visit is productive, bring a valid government-issued photo ID and a detailed work history covering the last 15 years. You should also provide a comprehensive list of your treating physicians, including their contact information and addresses. Bring copies of your most recent medical records, a current list of all medications, and any prior denial letters if you are reapplying. Plan for your appointment to last between 45 and 90 minutes as a representative reviews your file.

Many applicants face delays because they submit incomplete work histories or fail to provide recent medical records from all treating providers. Forgetting to disclose mental health conditions or other secondary impairments can also weaken your claim. Avoid signing any forms at the office without fully reading and understanding the information provided. Taking the time to organize your paperwork beforehand prevents unnecessary follow-up visits.

Should you bring an attorney?

The application stage is the foundation of your entire disability claim. Most applicants who apply without legal guidance find themselves facing a denial that could have been avoided with better evidence preparation. A qualified attorney can help you navigate the complexities of your initial filing to ensure your case is as strong as possible. You can request a free case review to understand your options before you head to your appointment.

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