I just bought a TRD Pro Gril used off eBay and I cannot tell if it is real or fake. The part number on the inside is PZ323-35055. Is this a legit part number? I try looking it up but nothing really comes up. Part PZ323-35056 is showing up as the right part number.

Some images I uploaded to imgur about the grill I got in today.

seems legit. My fake doesn't have all this stuff on the back.

Agree with Luke ^^

I have the Chinese rep on mine, and it has none of the identifying info on the back. I'd be surprised if they took the time to put all that on as most people wouldn't know or care.

I agree with the above; real.

Looks legit. Btw, how are the Toyota letters held on? Glue is real. Double side tape is replica.

Doubtful anyone other than the person you purchased from will be able to confirm with 100% certainty the authenticity of the item you purchased. While highly unlikely a replica would have such detailed information, it's not completely unreasonable that a replica manufacturer would include this in their process to try and sell for close(r) to OEM price. It is is a stretch though, as Toyota is very protective of the brand (confirming VIN prior to selling and whatnot), and buying OEM from a non-Toyota authorized dealer would raise obvious questions.

You would be better suited going through the seller to obtain information of how/where it was sourced. Did it come off of his personal TRD Pro? If so, some pictures/vin # would suffice. If he purchased from someone else, a receipt would likely answer your question as well. If it's legit I'm sure he would be happy to respond, as eBay always sides with a buyer in circumstances of an "item not as described" case. I know this from 10+ years of selling on eBay.

Good luck
