I've seen different numbers in the same font on many circuit boards. What does it typically mean?

Usually it's the date code.
At my company that code would mean 2019 week 1 (first week of jan). We also do a shift number as a 3rd part.
It's also common for the second number to be months.
Interesting! So this would end up meaning that you'd need to send new gerbers between production runs?
Or is this one of the edits that the fab house does to the gerbers without customer intervention (once asked, of course).
I've never really thought about how it's done on the older generation parts. On the newest it's etched by laser. We had a generation where it was stick on barcode and that was the worst.
