You don't have to and shouldn't give your Social Security number to everyone who asks. It is for tax purposes only - and you won't like get a loan without one but otherwise - don't! Places I have been asked and declined - college library, gym, doctors offices, health insurance paperwork - I have had secretaries say they can't process paperwork and I smile sweetly and say well it is against the law to require it. They will find a new number for you.
