Hey guys I did 9 searches in the forums and came up with nothing.....I wanted to know how you guys go about numbering your BPs with ID numbers?

I know with clutches it's usually the year, the clutch number, and the number in the clutch (eg: 11-3-01 2011-clutch 3-hatchling #1)

But what about snakes you already own and breeders? Do you just do the year they were born and then give them a number? I am increasing my collection and want to be able to label them with numbers to more easily keep track, even though they all have names I want them to have "official" IDs for my record keeping. Thanks for the info!
