What to bring when you visit

Bring a valid photo ID — a driver's license, passport, or state ID card. If you do not have one, bring two documents that show your name and date of birth, such as a birth certificate and a utility bill.

Bring any documents related to your case. If you are applying for retirement benefits, bring your birth certificate, proof of citizenship or legal residency, and recent tax returns or W-2 forms. If you are filing for disability, bring medical records and a list of doctors who have treated you. If you need a replacement Social Security card, bring your birth certificate and proof of citizenship.

If someone else is handling your case, bring a signed power of attorney or representative payee form. Social Security staff can tell you which form you need when you call ahead.

Calling instead of visiting in person

You can reach the Sioux Falls office directly at 1-866-564-2262. This is a local number for the Sioux Falls area. Wait times on the phone are often shorter in the morning and mid-week.

For general Social Security questions that do not relate to your specific case, you can also call the national line at 1-800-772-1213. This line handles questions about how benefits work, what documents you need, and whether you might be may have access to to benefits. Representatives are available Monday through Friday, 7 a.m. to 7 p.m. Central Time.

If you are deaf or hard of hearing, call the TTY number at 1-800-325-0778 during the same hours.

Handling matters online or by mail

Many Social Security tasks do not require a visit. You can create an account at ssa.gov to view your earnings record, check the status of a pending case, and request a replacement Social Security card in some states. South Dakota allows online card requests if you have a state ID or driver's license.

You can also request documents by mail. Send a letter to the Sioux Falls office at the address above, include your name, date of birth, and Social Security number, and describe what you need. Include a copy of your ID and any supporting documents. Mail typically takes two to three weeks to process.

If you are filing for benefits for the first time, you can start the process online at ssa.gov and then complete it by phone or in person. This can shorten the overall time from start to approval.

What to expect during your visit

When you arrive, check in at the front desk. You will receive a number and be called when a representative is ready. Visits typically last 15 to 45 minutes depending on the complexity of your case.

The representative will review your documents, ask questions about your work history and family situation, and explain what happens next. If your case is straightforward, they may be able to process it on the spot. If it requires investigation — for example, if you are filing for disability — they will tell you the timeline and what additional information they need.

Ask for a receipt or case number before you leave. This gives you a reference point if you need to follow up by phone.

If you cannot reach the Sioux Falls office

If the Sioux Falls office is closed or you cannot get through by phone, you have other options. The national Social Security line at 1-800-772-1213 can answer questions and direct you to resources. You can also visit ssa.gov to find other offices in South Dakota or to handle your matter online.

If you are in a rural area far from Sioux Falls, Social Security sometimes holds outreach hours in smaller towns. Call the Sioux Falls office to ask whether they visit your area and when.

For urgent matters — for example, if you need a replacement card before a specific date — explain the timeline when you call. Staff can sometimes prioritize cases or suggest faster alternatives.
