In order to receive warranty coverage, you should have activated your warranty within thirty days of the purchase date and be found in the CROC Warranty Database. If you are not found in the CROC Warranty Database, you can still establish your warranty coverage by providing our company with a valid receipt from an authorized vendor, showing the unit has been purchased within the warranty period. Receipts not accepted: handwritten receipts without the proper business information as required by the company, credit card statements, or other forms of receipts which the company considers non-valid.
