Before answering your question, I want it to be clear that without pictures of the bag and the creed, the authenticity can't be confirmed. (Just because a bag might have a seemingly valid serial number, it's not necessarily an authentic bag. Counterfeiters can copy "real" serial numbers to put on fakes.)
On an authentic bag, the serial number you've posted means that bag would have been made in March, 2013.
