Who Should Require Your Social Security Number?

There are some government agencies (tax, welfare, Medicare and motor vehicles) who can lawfully require your SSN. Other agencies may request your SSN in a manner that implies you must give it.

You can determine whether the agency has a right to your SSN by reading the disclosure statement that is mandatory on government forms requesting the number. The disclosure statement will tell you if the SSN is required or optional. It also states which agency is requiring the number and what it will be used for. Government agencies have strict laws about the use and storage of SSN’s – private agencies or businesses do not.

You cannot be denied services from government agencies if you refuse to give your SSN unless they are legally required to obtain it or had a law in effect before January 1, 1975 requiring a SSN.

Employers must obtain your SSN to report earnings and payroll taxes. While they are required by law to have your SSN you might ask for them to protect your number if it is used for filing, listed on ID badges or otherwise made public.

Other businesses or agencies, including private medical insurance and schools, may request your SSN. If they are federally funded schools or are reporting to the IRS they may have a legal right to the information. If the reason for the request is not listed on the form you can leave the space provided for your SSN blank and ask for an explanation of why they are requesting it.




While a business may have no legal right to the information they can refuse service if you choose not to disclose it. State laws differ but businesses should not willfully display SSN’s, however, carelessness or inadequate protection of SSN’s may not violate these laws.

Financial information that is of interest to the IRS requires your SSN to be listed. Banking, stocks, employment and other financial statements all must include the number.

Credit card companies may request your SSN but are not legally required to have it. Since the number is used to validate who you are you may be able to provide proof with other forms of identification. Be prepared to have a difficult time finding a creditor who will provide credit if you refuse to submit your SSN.

Since potential creditors (including landlords) may wish to see your credit report you will likely be required to give them your SSN to obtain the report. You may ask if they will accept a current report without the SSN and confirm your identity with other forms of ID.

Federal records, including driver’s license, divorce papers, child support and death certificates all require SSN’s. Birth certificates usually require the SSN’s of both of the parents unless there is good cause for not requiring it.

If you receive email that appears to be from a service provider or government agency that requests your SSN do not reply. This information will not be requested through unsolicited emails and is being sent from a fraudulent source.
