Using a credit card is an efficient way to keep track of your purchases. Whether you make payment with the credit card in person at a retail store, online, via phone or through the mail from a catalog, proof of your purchase is simple to locate. You may misplace or toss your receipt because you don't think you will need it, yet later a proof of purchase is required to exchange the item or receive a refund.
Look at the credit card statement each month when you receive it. It will have your proof of purchases in the list of transactions, with a reference number, date of purchase, store and total amount charged to your account, according to the Federal Reserve website (see the Resource section). Items purchased are not listed separately on your statement, only the total sales amounts. However, this will give you a reference for when the item was purchased.
Search the credit card company website for your online statement. Once you locate the statement that you need, you may print it out for your proof of purchase.
Call the credit card company if you do not have an online account or if you never look at your statements and toss them into the trash. Request copies of statements to be mailed to you. There may be a minimal charge assessed, so ask your credit card company before making your request.
Email the credit card company and explain the proof of purchase that you require. They can review the statements and send it to you in a return email.
Ask the store where you bought the product to scan the credit card that you used and see if your purchase can be pulled up. Some stores have systems that show proof of purchases attached to the card, if you don't have a receipt.
