The copyright and registration marks return around the CHANEL, as well as MADE IN FRANCE along the bottom. On either side of the CC logo are the the two digit date and the one letter Season (P for Spring/Printemps, A for Autumn/Automne).

How can I tell the year of my Chanel bag?

The year the bag was made is determined by the amount of digits in the serial number, and the first digit(s) in that serial number. If your bag has 8 digits, it was produced between late 2005-current.
