I don't think there really is a standard labeling technique used by breeders. Most just develop their own method, either by giving each snake in their collection a number or name, then year of birth etc.
Thus, use whatever naming convention works for you.Accurate notes is the important thing. You have to be able to identify which snake is which using the naming convention, so if somebody buys baby A/hAn2/0607 and asks what it is, you can say Albino (amel) het Anery type 2, born June 2007
The herp breeders programs available on the market (typically for free I beleive) may also have their own built in naming convention which the program will automatically pump out according to what information you put into the program. Detailing parents, date of clutch laid and hatched, and details about the offspring may produce labels you can attached to the offspring for your own records for those you sell and hold back.
As I have never used any of those programs, I can't say for sure if they do give you such name tags.
The big breeders will of course have more info on this subject than I, sending an email to them or giving them a call certainly will be beneficial. It doesn't even matter if they are corn snake breeders or not. If there is a naming convention it probably work across the hobby not just species specific.
