Avodart Authenticity

[samgreen]

I recently bought an Avodart Pack and I realised there is a number written on the blister pack (not the Lot. No.), the number written below GlaxoSmithKline. I checked the dust flap of the cardboard box and the number was slightly different (see pictures). I want to know what is the significance of these numbers, as I'm being paranoid about the fact that the blister packs might have been replaced or something.
Please if someone is using Avodart, check if it's the same situation.
Note: the Lot No. is the same on both.

Where is your Avodart made? I don't see any number written on the blister pack, and it's made in Poland.
