GS3 numbers or letters lower rt corner

Im looking to get a gs3 off eBay. I seen one that has number or letters in the lower right hand corner if the screen, is this a testers phone??

Mine doesn't and it's a normal phone.

I've never seen one like this. My old thunderbolt was etched on the side. I seen moto's etched into the upper rt corner of the glass. I wonder if this is how Samsung did it.
