If you cannot find your card or those documents, you have other ways to retrieve your number without leaving home or visiting an office. The Social Security Administration offers online and phone options specifically for this purpose.

Pension or retirement account statements from your employer or a financial institution will have your number on file.

Medical records from hospitals or doctors' offices may have your Social Security number, though this varies by provider. Utility bills and property tax records sometimes include it. The key is that if you have any official document linked to your financial or legal history, your Social Security number is likely printed on it somewhere.
