What information must a customer provide for returns?

For returns, the most crucial piece of information a customer must provide is proof of purchase. This typically means supplying a receipt or a transaction number that confirms the item was indeed purchased from the store. Proof of purchase is essential as it validates the transaction and allows the store to process the return efficiently.

While providing a name and phone number can sometimes assist in identifying the customer or tracking return history, they do not typically establish a legitimate basis for a return on their own. The specific details of the return policy often require evidence of the transaction to ensure that the item being returned was purchased under the store's guidelines. Therefore, proof of purchase stands out as the primary requirement for the return process.
