Credit card companies have this kind of info.
Oh really, don't know how it is in the US, but in Canada this is explicitely when it is not allowed for your SIN (SSN in the US) to be be requested. It is STRAIGHT ON THEIR WEB SITE.
- Proving your identity (except for specific government programs)
- Completing a job application before you get the job
- Completing an application to rent a property
- Negotiating a lease with a landlord
- Completing credit card application
- Cashing a cheque
- Applying for a video club membership
- Completing some banking transactions (mortgage, line of credit, loan)
- Completing a medical questionnaire
- Renting a car
- Subscribing to long-distance or cellular telephone services
writing a will
- applying to a university or college.
Anyone who asks it in all of those cases can get into trouble, big fines, etc.
If the US allows any of these uses, well the US is a really dumb place to live...
Those that are allowed (very short list):
- Your employer
- Most financial dealings with the government, including taxes, pension plans, all kind of benefits programs, etc.
- Fnancial institutions from which you earn interest or income (for example, banks, credit unions, trust companies)
That's it. Pretty restricted hmmm...
