Home Depot's general policy was to keep records of customer receipts for up to two years. This means that if you need a copy of your receipt for a purchase made within the past two years, they should be able to look it up in their system.
Keep in mind that policies may vary slightly depending on the specific store location and local regulations. To obtain a copy of a receipt, it's best to contact the Home Depot store where the purchase was made and inquire about their receipt lookup process. You may need to provide some information related to the purchase, such as the date of purchase, the method of payment used, and the items purchased, to help them locate the receipt in their system.
