A Uniform Product Code that is going to The Home Depot will require the Order Management System Identification Number (OMSID) within the WERCSmart registration. OMSID is provided by The Home Depot and is a 9-digit identifier. For a registration's assessment to finalize to the retailer (The Home Depot), the OMSID system you provide with the UPC(s) must match the OMSID within The Home Depot's systems. Otherwise, you may receive an OMSID error and the assessment will not transfer to the retailer. To fix an OMSID error on a registration, use the Edit UPC option.
