Sprint requires your Social Security number in order to run a credit check before they will allow you to open an account, according to a store manager in Silver Spring, MD. Since Sprint is the exclusive carrier for the Palm Pre, if you are not willing to provide an SSN, you can't buy this product. I believe a full credit check for this level of consumer purchase is a clear example of overkill. I have supplied an SSN when buying a house and renting an apartment, but never for any other consumer purchase. I have purchased my cars with cash so far, so I don't have first-hand experience, but a car loan also seems to be an appropriate place to require an SSN for a credit check. At the very least, Sprint should have an alternative for people who don't want to give out their SSN. I also found the entire experience a powerful argument against exclusive license agreements
