Social Security does not accept faxes for most requests

The Social Security Administration (SSA) does not publish a general fax number for the public to send documents or questions. If you have seen a fax number listed online, it is likely an internal office number or a number that is no longer in use. The SSA moved away from fax as a primary contact method years ago and now directs people to phone, mail, or their online account instead.

If you need to send documents to Social Security — such as proof of citizenship, a birth certificate, or medical records — the standard route is to mail them to your local Social Security office or to the address listed on any letter you received from SSA. You can find your local office address by visiting ssa.gov and using their office locator tool.

For time-sensitive matters, calling Social Security's main number is faster than any written method. The national customer service line is 1-800-772-1213, available Monday through Friday, 7 a.m. to 7 p.m. Eastern Time. You can also create a my Social Security account online to check your status, update information, and request certain documents without calling.

Key Takeaways

  • Social Security does not maintain a public fax line for document submission or general inquiries.
  • Mailing documents to your local Social Security office or the address on your SSA letter is the standard way to send paperwork.
  • Calling 1-800-772-1213 during business hours is faster than fax or mail for most requests.
  • Creating a my Social Security account online lets you check your record, update your address, and request a replacement Social Security card without calling.
  • If you have a specific case number or are following up on an existing claim, include that information in any written correspondence.

When to mail documents instead of faxing

You should mail documents to Social Security when you are submitting original or certified copies that SSA requires for your file. Examples include a certified birth certificate, marriage certificate, divorce decree, or medical evidence for a disability claim. These documents need to be part of your official record, and mailing ensures they are logged and stored correctly.

Include a cover letter with your name, Social Security number, date of birth, and a brief description of what you are sending and why. Keep a copy for yourself and consider using certified mail with return receipt so you have proof of delivery. Processing times vary, but expect two to four weeks for mailed documents to be reviewed and added to your account.

Using my Social Security to avoid mailing altogether

The my Social Security online account is the fastest way to handle many tasks without mailing or calling. You can create a free account at ssa.gov/myaccount using your email address and a password. Once logged in, you can view your earnings record, check your benefit amount, update your address or phone number, and request a replacement Social Security card.

If you need to submit documents through your online account, some services allow you to upload images directly. For example, if you are requesting a replacement card and need to verify your identity, you may be able to upload a photo of your driver's license or passport through the portal. Not all services support document upload, so check the specific request type to see what options are available.

Calling Social Security when fax is not an option

Phone is the most direct way to reach a live representative at Social Security. Call 1-800-772-1213 Monday through Friday, 7 a.m. to 7 p.m. Eastern Time. Wait times are typically shorter early in the week and earlier in the day. Have your Social Security number, date of birth, and any relevant case or claim numbers ready before you call.

If you are deaf or hard of hearing, you can use TTY by calling 1-800-325-0778. If you speak a language other than English, Social Security offers interpretation services at no cost — tell the representative your language when you reach them, and they will connect you with an interpreter.

What to do if you have already faxed something to Social Security

If you faxed a document to a number you found online, it may not have reached the right place. Call 1-800-772-1213 and explain what you sent, when you sent it, and what it was for. A representative can check whether the fax arrived and, if it did not, tell you the correct mailing address or help you resubmit through another method.

Do not assume the fax was received just because you sent it. Social Security's systems do not track incoming faxes the way they track mailed documents, so a fax can easily be lost or sent to an office that cannot process it. Following up by phone ensures your documents are actually in your file.

Mailing addresses for different Social Security requests

The address you mail to depends on what you are requesting. For general correspondence, use your local Social Security office address, which you can find at ssa.gov/locator. For appeals of a denied benefit claim, the address is different and will be listed on the denial letter you received.

If you are submitting medical evidence for a disability or Supplemental Security Income claim, send it to the address listed in your case file or on any letter from SSA. If you are unsure which address to use, call 1-800-772-1213 and ask — it takes two minutes and prevents your documents from being sent to the wrong place.

Frequently Asked Questions

Can I fax my birth certificate to Social Security?

No, you should mail a certified copy of your birth certificate instead. Social Security needs original or certified documents in your file, and faxes are not accepted for this purpose. Mail it to your local Social Security office with a cover letter that includes your name, Social Security number, and the reason you are sending it.

What if I need to send something urgently?

Call 1-800-772-1213 and explain the situation to a representative. They can tell you whether your request can be handled over the phone or whether documents must be mailed. For truly time-sensitive matters, you can visit your local Social Security office in person with your documents and ask them to process it on the spot.

Is there a fax number for Social Security's appeals office?

No, appeals are handled by mail or through your online my Social Security account. The address for appeals is listed on the denial letter you received. If you have questions about the appeals process, call 1-800-772-1213 and ask to speak with someone in the appeals unit.

Can I upload documents to Social Security instead of mailing them?

Some services allow document upload through your my Social Security account, but not all do. Log in to your account and check the specific request type to see if upload is an option. If upload is not available, you will need to mail the documents or call to ask about other methods.

How long does it take Social Security to receive a mailed document?

Mailed documents typically arrive within one to two weeks, depending on your location and the postal service. Once received, Social Security usually takes another two to four weeks to review and add the document to your file. Using certified mail with return receipt gives you proof of when it was delivered.
