Your local SSA service center
Your local Social Security service center in Chatsworth manages a caseload that skews heavily toward retirement. With 101,645 total beneficiaries served, the office facilitates $188 million in monthly payments across 27 ZIP codes. While disabled-worker beneficiaries make up 6% of the local population, the office remains the primary location for your initial SSDI applications and document verification.

At the Chatsworth office, you can file initial SSDI applications, drop off medical records, verify your identity, and update your direct deposit information. Note that this office does not make final disability determinations, which are handled by the state, nor does it conduct hearings, which occur at separate locations. While you may be able to walk in for some services, scheduling an appointment is recommended to minimize wait times. Always check your appointment notice to see if you are required to appear in person.

Beneficiaries in this service area receive an estimated $188,155k in Social Security benefits each month.
Before you visit
To prepare for your appointment at Chatsworth, bring a valid government-issued photo ID and a detailed 15-year work history. You should also provide a complete list of your treating providers with their contact information, recent medical records, a list of current medications, and any prior denial letters. Being organized with these documents helps the representative process your information more efficiently.
Avoid common pitfalls that delay your claim, such as submitting an incomplete work history or failing to include contact information for all your recent medical providers. Never sign an application or any other form without reading it thoroughly to ensure all information is accurate. Providing incomplete or inconsistent data is a frequent cause of processing delays.

Should you bring an attorney?

Most applicants who go through the process alone face significant hurdles if their initial application is denied. An attorney can help you gather the necessary evidence and ensure your application is as strong as possible from the start.
