As a result of changes to federal regulations, we now require all Amazon
Payments accountholders to provide a Tax Identification Number (TIN). For
customers with Personal Accounts, your TIN is your Social Security Number.
From December 31st 2011, accounts without an associated TIN will no longer
be able to receive incoming funds. We apologize for any inconvenience this
may cause.
