The Social Security Administration is the federal agency that runs Social Security, Medicare, and Supplemental Security Income

The Social Security Administration (SSA) is a standalone federal agency that manages three major programs: Social Security retirement and survivor benefits, Social Security Disability Insurance (SSDI), and Supplemental Security Income (SSI). If you receive a Social Security check, have a Social Security number, or need to report a change to your account, you are dealing with the SSA.

The SSA does not run Medicare itself — that is handled by the Centers for Medicare & Medicaid Services — but the SSA enrolls you in Medicare when you turn 65 and handles some of the paperwork. The agency has about 60,000 employees working in field offices, processing centers, and the Office of Inspector General across the country.

Understanding which SSA office or service handles your specific need saves time. The agency operates through local field offices (where you can meet in person), a national customer service phone line, an online portal called my Social Security, and mail. Each route works best for different situations.

Key Takeaways

  • The SSA runs Social Security retirement benefits, disability benefits (SSDI), and Supplemental Security Income (SSI) — three separate programs with different rules.
  • You can reach the SSA by phone at 1-800-772-1213, through your local field office, or online at ssa.gov using the my Social Security portal.
  • The my Social Security account lets you check your earnings record, request a replacement Social Security card, and report changes without calling or visiting an office.
  • Local field offices handle complex cases and in-person needs, but wait times vary widely by location and time of year.
  • The SSA processes millions of claims each year, so response times for new claims or appeals can stretch from weeks to months depending on the type of claim.

How to contact the SSA by phone, online, or in person

The main SSA customer service number is 1-800-772-1213. This line handles general questions, claim status checks, and requests to report changes. Wait times are typically shorter early in the morning on weekdays and longer in mid-morning and afternoon. The line is open Monday through Friday, 7 a.m. to 7 p.m. Eastern time. You can also use the TTY number 1-800-325-0778 if you are deaf or hard of hearing.

The my Social Security portal at ssa.gov is the fastest way to handle routine tasks without waiting on hold. You create a free account using your email, Social Security number, and date of birth. Once logged in, you can view your earnings record, request a replacement Social Security card, check the status of a pending claim, change your address, and report a change in your work or living situation. The portal is available 24 hours a day, seven days a week.

Your local field office is the place to go for in-person help with complex situations — for example, if you need to bring original documents, if you are explore for benefits for the first time, or if you have been denied and want to discuss next steps. You can find your nearest office at ssa.gov/locator. Many offices now require you to make an appointment in advance rather than walk in. Call ahead or check the office's website to confirm hours and whether appointments are required.

You can also mail documents to the SSA, though this is the slowest route. The address depends on what you are sending and where you live; the SSA website lists the correct mailing address for your situation.

What the my Social Security account shows you and what it does not

The my Social Security portal shows your complete earnings record — the wages and self-employment income the SSA has on file for you, year by year. This is the record the SSA uses to calculate your retirement benefit amount. You should review it every few years to catch errors. If you spot a mistake, you can report it through the portal or call the SSA to correct it. Corrections are important because they directly affect your benefit amount.

The portal also displays your current benefit amount (if you are already receiving benefits), your estimated retirement benefit at different ages, and the status of any pending claim or appeal. You can request a replacement Social Security card, report a change of address, and update your direct deposit information.

What the portal does not do: it does not let you explore for benefits for the first time, appeal a denial, or handle complex situations like a representative payee arrangement or a work incentive program. For those, you will need to call the SSA or visit a field office.

The difference between Social Security retirement, SSDI, and SSI

These three programs are run by the same agency but have completely different rules, and the SSA treats them as separate cases. Social Security retirement is based on your own work record. You become may be able to access at age 62 (with a reduced benefit) or at your full retirement age (which varies by birth year, between 66 and 67). You can delay until age 70 for a larger benefit.

Social Security Disability Insurance (SSDI) is also based on your work record, but you do not have to be a certain age. You must have a medical condition that prevents you from working and is expected to last at least 12 months or result in death. The SSA has a strict definition of disability and denies most first-time claims. If you are denied, you can appeal.

Supplemental Security Income (SSI) is not based on your work record at all. It is a needs-based program for people who are 65 or older, blind, or disabled and have very little income or resources. The income and resource limits are strict — as of 2024, you can have no more than $2,000 in countable resources (the limit is $3,000 for a couple). SSI is run by the SSA but funded differently than the other two programs.

If you are unsure which program you are on or whether you might be on more than one, call the SSA or log into my Social Security to check.

How long it takes the SSA to process claims and appeals

Processing time depends on the type of claim and how complete your process is. A straightforward retirement claim filed online or at a field office typically takes two to four weeks if all required documents are included. A disability claim (SSDI or SSI) takes much longer — the SSA estimates 3 to 6 months for an initial decision, though some cases take longer if the SSA needs to request medical records from your doctors.

If your claim is denied and you appeal, the timeline stretches further. A reconsideration (the first level of appeal) takes another 2 to 4 months. A hearing before an administrative law judge takes 6 to 18 months depending on how busy the judge's office is. The Appeals Council review after that can take several more months.

You can check the status of your claim at any time through my Social Security or by calling 1-800-772-1213. The SSA will tell you what documents it has received and what it is still waiting for. If documents are missing, providing them quickly can speed up the process.

Common reasons the SSA denies claims and what to do next

The SSA denies retirement claims most often because the person does not have enough work credits. You need 40 credits to be may be able to access for retirement benefits (a credit is earned by working and paying Social Security taxes; you can earn up to 4 credits per year). If you do not have 40 credits, you are not may be able to access, and an appeal will not change that. However, if you continue working, you may earn enough credits to become may be able to access later.

Disability claims are denied most often because the SSA concludes your condition is not severe enough to prevent you from working, or because the SSA believes you can do other work despite your condition. The SSA uses a strict five-step process to evaluate disability, and most denials happen at step 4 or 5 — the steps that ask whether you can do your past work or any other work. If you are denied, you have the right to appeal. Many people win on appeal, especially if they provide additional medical evidence or hire a representative.

SSI claims are denied most often because the applicant has too much income or too many resources, or because the SSA determines the person is not disabled under its definition. Unlike retirement and disability, SSI has strict income limits, and even part-time work can disqualify you.

When you need a representative to deal with the SSA

You do not need a representative to file a claim or check your account status. Many people handle their own cases successfully. However, a representative — either a lawyer, a non-lawyer advocate, or a community organization — can be helpful if your claim has been denied and you are appealing, if your case is complex (for example, if you have worked in multiple countries or have a criminal record), or if you are having trouble gathering medical evidence.

The SSA has a list of accredited representatives on its website. Representatives can charge a fee, but the fee is capped at 25 percent of your past-due benefits (the money owed to you from the date you became may be able to access), and the SSA must approve the fee. Many legal aid organizations and disability advocacy groups offer representation for free or at low cost.

If you hire a representative, they can contact the SSA on your behalf, request your file, and represent you at a hearing. You still have to sign forms and provide information, but the representative handles the back-and-forth with the agency.

Frequently Asked Questions

Can I explore for Social Security benefits online?

You can explore for retirement benefits online at ssa.gov if you are at least 61 years and 9 months old. You cannot explore for disability (SSDI) or SSI online; you must call 1-800-772-1213 or visit a field office. The online retirement process takes about 15 minutes and you get a confirmation number when ready.

What do I do if the SSA says I owe money back?

If you received benefits you were not may have access to to — for example, because you did not report work income — the SSA will send you a notice explaining the overpayment and how much you owe. You can request a waiver (asking the SSA to forgive the debt), ask for a payment plan, or appeal the overpayment decision. Call the SSA or visit a field office to discuss your options before ignoring the notice.

How do I report a change in my income or living situation?

You can report changes through my Social Security, by calling 1-800-772-1213, or by visiting a field office. Changes that matter include starting or stopping work, a change in your address, a change in your marital status, or a change in who lives with you. Report changes promptly because failing to report can result in an overpayment you will have to repay.

What if I lost my Social Security card?

You can request a replacement card through my Social Security without calling or visiting an office. Log in, select "Replacement Social Security Card," and follow the steps. The card will arrive by mail in 1 to 2 weeks. You can also request one by calling 1-800-772-1213 or visiting a field office in person.

Can I work while receiving Social Security retirement benefits?

Yes, but if you are under your full retirement age and earn more than a certain amount, the SSA will reduce your benefit. As of 2024, the limit is $23,400 per year if you have not yet reached full retirement age. Once you reach full retirement age, you can earn any amount without a reduction. The earnings limit changes each year, so check ssa.gov for the current year's limit.
