Yes! Omg I have been flat-strap; changing jobs and wedding planning and...buying more Postal Bags XDHi, did you manage to find out about the codes from your SA? Sorry I've been MIA. I read through the forum and someone mentioned it imprinted on the leather? I searched my bag and actually found the code!
Owe you a mod shot! Couldn't get a mod shot but here it is..absolutely in love with it!
My SA said they seem to be moving to the imprinting, as the tags are easy to rip out/have fallen out with a lot of use, but it's a gradual process. She couldn't tell me how many artisan factories (for lack of a better word) they have due to ~trade secrets~, but Puzzles eventually will all move to printed. Safer, I think! She also mentioned there's no plans to add serials to any other styles at this point (I asked as the Postal is ltd edition she mentioned, or "testing" the ground, as she said), and they'll continue their SA/registration program/QC paperwork style of working.
And look at your baby!! Don't tempt me to get the spray...#LoeweGangEnablers XD
