Serial Number on HP memory

Hello,

So I have to list the serial numbers for each stick of memory I recently bought in order to get a rebate. But I have no idea which number to put down. It’s either the S/C number or the number right below where it says “security ID.” What do you guys think?

Thanks in advance
