What counts as proof of purchase in the United States?

Start with the receipt: the FTC says it "proves the date you bought the product and that you're the original product owner". Whether another record will do depends on who is asking.

For a change-of-mind return, the retailer's own policy decides what proof they accept. For defective goods, UCC § 2-607 puts the burden on the buyer to establish the breach without naming any particular document, so records that identify the seller, the date, the amount and the item all help.

The legal reality: Change of mind vs defective goods#

Under United States commercial law, there is no federal statute requiring stores to accept returns for items you simply no longer want.

• For voluntary / change-of-mind returns: The retailer's written policy governs the transaction. If a retailer explicitly posts that returns require an "original printed register receipt," they are legally permitted to enforce that term.
• For defective or misdescribed goods: Under Article 2 of the Uniform Commercial Code (UCC § 2-607), a buyer is only required to notify the seller of breach within a reasonable time. The UCC does not mandate a register receipt and prescribes no particular form of proof. What a court or arbitrator accepts is an ordinary question of evidence: records identifying the seller, the date, the amount and the item are what make a purchase provable, and a single card-statement line usually is not enough on its own.

Evidence that may help#

For a voluntary return, the retailer decides what proof to accept under its own policy. Check that policy before visiting the store. Useful records include an itemized receipt, order confirmation, digital receipt, loyalty-account history, packing slip, or card statement. A retailer may be able to look up a card or account purchase, though how far back its system searches varies from store to store.

For a warranty or defective-goods dispute, keep every record that connects the item to the seller: the receipt or order confirmation, payment record, product serial number, warranty documents, and communications with the seller. The weight of that evidence depends on the facts and the law of the relevant state.

What if you only have a bank statement?#

A bank or credit card statement proves that you spent money with a merchant on a specific date, but it does not prove which items you bought.

If you bought a single $350 power tool and your bank statement shows a single charge of $350.00 at Home Depot on that date, customer service will frequently cross-reference their database to locate the SKU. If you bought six items totaling $142.18, a bank statement alone cannot prove that a particular returned blouse was part of that total.

For a warranty claim, a bank statement is stronger when it is paired with an order confirmation, product serial number, warranty registration, or other record identifying the item.
