Probably a serial number for the stamp. In the US, you can even pay online and print your own stamp, and it uses the barcode to track when you use it, so it can’t be used twice.

What are the QR codes next to the stamp for? We don’t have these in Australia.

That’s really cool. We can’t do that in Australia, would be handy if we could!

You are right but I do sometimes see that same type of barcode stamped on some Australian letters but I’m not sure what it’s used for

Those aren’t QR codes like you are thinking. Its used internally by the post office.

They are used internally but they aren’t exclusive to post offices

Fellow Aussie, equally confused.
These are actually so much cooler than I was expecting!
