No label on the bottom of my new router?

I just bought a new GL-XE3000 and I’m trying to get it running. I got the sim in but I can’t get past the default password because I can’t locate the “label on the bottom of my router”. The bottom of my device is just blank. There are no stickers or anything on it. Any help is appreciated.

UPDATE* I figured out the wall mount was a separate piece and was concealing it.
