I ordered an Alma BB a few months ago and I couldn't find the date stamp code either. I assume it's microchipped by now (sounds like a dog or a cat).I’ve recently bought two new LV bags. Graceful mm monogram (received yesterday) and Neverfull empreinte (received 10 days ago) The Graceful does not have any date code, the Neverfull has. Its produced in 2021. Don’t remember the exact week.
