If your product was purchased from an OtterBox authorized retailer, and that product is still within the applicable warranty, then your damaged product is eligible for a warranty replacement.

Does OtterBox replace a phone if it breaks? No. OtterBox will replace a broken/damaged case, but the warranty does NOT cover any damage to the phone. Some cellular carriers sell 'accidental damage' warranties for the phones they sell.

There is no requirement to register your OtterBox case for warranty. However, you may need to provide proof of purchase from an authorized dealer when submitting a warranty claim. Keeping your purchase receipt or invoice for warranty is always a good idea.
