If you are trying to determine the date you purchased the used phone you would contact the store where you purchased it.

If you are trying to determine the original date to see if it is covered under warranty, the following may help: https://selfsolve.apple.com/agreementWarrantyDynamic.do

If you are trying to determine where you are in a contract with a cellular carrier, contact the cellular carrier.

If you want help then contact Apple Support directly.

These are user to user technical support forums and NOT Apple Support, so nobody here can help you.

Hi

Regrettably, none of the links provided on this thread will give a purchase date or a manufacture date for iPhone.

In my research, this information is kept secret.

Not sure why you are replying to me -- I didn't say that the link I provided would give a purchase date.
