Yes, it is fake. Real ones are really sharp. Fake ones usually are blurred or not as indented in the case. See:

Only a few OtterBoxs have a serial number. Mostly new Samsung models. Apple models do not have a serial number. Even the new iPhone 6 plus lacks the serial number. See:

Currently, no counterfeits have a serial number. So if yours has a serial number, it is real. If it does not have one, it does not mean it is fake. Only a few models(Samsung) have a serial number. Otterbox took down their serial number check after I pointed out to them it returned any value as true. That was four months ago. They have yet to fix the problem.

I predict within a year, all counterfeits will have a serial. A few years ago, Otter put a hologram on top of the packaging to stop counterfeits. Within a year, fakes started to have that hologram. Now that feature is useless.

It does not. It is a popular scam to buy from companies that accept returns for any reason, like AMZN, or BBY, and return a counterfeit one and sell the real one or keep it. Happens all the time. Customer return centers are not trained to inspect for authenticity for returns when the product is cheap.

Another scam that is popular is to buy a counterfeit Otter from China(around $5) and break the case. Since Otterbox only requires a picture for a return, a person can break a counterfeit, and get a real Otterbox in return. It is very profitable since OtterBoxs can retail for over $60 for some models.

Counterfeit OtterBoxs have become so good, it is hard to tell unless you have a side by side comparison. The iPod's are the best counterfeits I have seen. The round edges make it a perfect for counterfeiting. See this post. It is impossible to tell the two different if you did not have the retail case. If you had just bought the case, and not the package, you would be out of luck:

I made these guides to help people tell the difference. I should have the rest of the models up by the end of the month. It is expensive and time consuming to make these posts. So far I have bought over $1000 in real Otter cases to take pictures and $500 in counterfeits. Maybe I will open a museum one day. It is insane how close the counterfeits are to the real ones. It was not like this a few years ago. After all, counterfeiting is a national past time in China. A estimated 8% of their GDP is linked to counterfeiting. Take this story on how a whole city turned to a ghost town after authoritys went after counterfeiters:

In case you still cannot tell, please reply with as much pictures as possible and I will try to help you.

Please also note, the center box is the factory time stamp and the model. It is not the serial. The serial number is 11 characters/numbers long.
