Truck bed

[Petermay]

My bed has been switched, not sure what year. I have a 2012 GmC Sierra but the bed looks like a 2015. There is a sticker, bar code, behind the tail light. Can anyone decode it.                     T 2 ZA1794073 8 151183192 PPA HD

Can you post a picture of the truck/bed?

Definitely a GMC box, from a 2014-2019 Sierra 1500 or 2015-2019 Sierra HD.
