Magazine subscription number

I was just updating my profile, and got stuck where they ask for the magazine subscription number. There are two sets of numbers in the upper left hand corner of my magazine lable - one that is mostly zero’s and one that is very long (just underneith the one with lot’s of zero’s). Which one do I use?

Thanks!

Anyone?

This page from the main COTH site explains it. :slight_smile:
