Counterfeits look so much like the real thing, there are only a few details that are different.
The front of the packaging.
There is no difference except the color bar which is circled. They are very close, but are different.
The font of the model name on the fake package is a little bigger, however only some of the fake cases have that.
Close up of the colors:
Check out the QR Code too. Fakes usually have the wrong code. Scan it and see where it goes. It if goes to the wrong product, it is fake.
For other OtterBox models you could tell from looking at the bottom. Fake ones usually have bold font. However for this model it is opposite. The real one has bold and the fake one does not. But fake ones can have both. The Moto X is the only case that has bold on the right.
The UPC barcode also can be wrong if it is fake. Search the UPC and see what product it matches. Around 25% of counterfeits will have a proper UPC.
The back of the package is different for the real one. This is perhaps the only model I have found like this. Most of the time the back is the same:
The front is easy to tell:
If your OtterBox matches any of the counterfeit signs here, it is fake. Counterfeits will show at least one flaw.
Still not able to tell if your case is real or not? Leave a comment and I try to help you.
1.) Real OtterBoxs do not show flaws and counterfeits do.
I have had many brand new, non-counterfeited cases show major flaws to the design. I have also had many fake cases with perfect design.
2.) You can tell by how dark the Otter appears underneath the logo.
All new counterfeits that I have gotten in late 2014 and eary 2015 have fixed this. Now fake ones match the design perfectly.
3.) Counterfeit cases do not have a serial and real ones do.
That is halfway true. I have not seen a single counterfeit OtterBox that has a serial number. The thing is the vast majority of real OtterBoxs do not have one either. We have over 50 different OtterBox models. Only Samsung’s Note 4 and Galaxy S5 have serial numbers. The iPhone 6 plus sometimes has a serial. So if your case does have a 11 character serial, it is real. Once I see counterfeits having them, I will update this note.
