If you request a Social Security Statement, Proof of Income Letter, Form 1099-Social Security Benefit Statement or a Replacement Medicare Card online, the information you enter is used to match the information the Social Security Administration has on record from your original application for a Social Security number.

To help ensure that only you receive information from your records, Social Security will not process your request if the information you enter does not match their records. To increase the security, Social Security does not tell you which field failed to match.

For the Social Security Statement: Social Security suggests that you download the form  and mail it in. The request will be reviewed and you will be notified of what action, if any, you may need to take to correct or update your record. For Proof of Income Letter, Form 1099-Social Security Benefit Statement or a Replacement Medicare Card: call or visit your local office to request the letter or statement that you need.

You can find your local office on the Social Security Administration’s Web site. Or, call 1-800-772-1213 and request your statement or letter. Social Security employees can also help you determine why your request did not match their information and tell you what corrections, if any, are necessary.
