Yep that's the production date, as AVB says.
But the other numbers don't look to be correct - could the Model be 98902? And the Type should follow the format XXXX-XX; i.e. 6 digits in all.
Try rubbing a piece of chalk across the numbers, then wiping off the excess. This often makes them easier to read.
Cheers,
