Counterfeits look so much like the real thing, there are only a few details that are different.
The front of the packaging.
Notice the logo, QR code, and color bar.
The colors are so close it is hard to tell. However the fake one has a different shade of grey.
The design of the logo used to be different, but new counterfeit designs have it the same as the real one. However some fake ones still show a darker counterfeit logo:
There are two ways to check at the bottom for authenticity. However the bottom only works sometimes. I have a had a few fake cases that matched the font 100% and the barcode matched the real UPC.
But most fakes did not do that. If you think you have a fake one, enter the UPC code online and see what product it matches. Counterfeits usually have bold font on the right side.
Now for the case itself, there are many ways. The best way is just to find the serial. At this time, there is not a single counterfeit that uses a serial number. So if you find one, it is real.
However in the event that counterfeiters start using them, here is another way to tell. Notice the real one does not have a border around the Otter logo:
Close up of the real one:
Now see the border around the fake one:
If you find the serial on the hard back piece, it is real.
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.
