Lock code needed when erasing all contacts on sch-u740 cell phone

Bought a used samsung sch-u740 and I want to erase the contact list.  When I go to "erase all" I get a message saying I need a "lock code" and there is a place to enter four numbers (has to be numbers).  Is this a standard feature that Samsung supplies the lock code?  Or do I need the lock code that the previous owner made up?  I emailed the ebay guy who sold me the phone, but havent' received a reply yet.

    I don't know how you can find out what the old number was since you already activated it with your new number. Try the last 4 digits of your number and see what happens.. if not I guess you're going to have to delete each phone book entry manually.

this happened to me once with picture messages too, and i just called verizon and they took me through a step by step process and helped me fix it. I think it was that my phone just needed to be flashed or upgraded or whatever. They give you the number to call and do this.
