12 CFR § 226.8 - Identifying transactions on periodic statements.
(a) Sale credit.
(1) Except as provided in paragraph (a)(2) of this section, for each credit transaction involving the sale of property or services, the creditor must disclose the amount and date of the transaction, and either:
(i) A brief identification 17 of the property or services purchased, for creditors and sellers that are the same or related; 18 or
(ii) The seller's name; and the city and state or foreign country where the transaction took place. 19 The creditor may omit the address or provide any suitable designation that helps the consumer to identify the transaction when the transaction took place at a location that is not fixed; took place in the consumer's home; or was a mail, Internet, or telephone order.
(2) Creditors need not comply with paragraph (a)(1) of this section if an actual copy of the receipt or other credit document is provided with the first periodic statement reflecting the transaction, and the amount of the transaction and either the date of the transaction to the consumer's account or the date of debiting the transaction are disclosed on the copy or on the periodic statement.
(b) Nonsale credit. For each credit transaction not involving the sale of property or services, the creditor must disclose a brief identification of the transaction; 20 the amount of the transaction; and at least one of the following dates: The date of the transaction, the date the transaction was debited to the consumer's account, or, if the consumer signed the credit document, the date appearing on the document. If an actual copy of the receipt or other credit document is provided and that copy shows the amount and at least one of the specified dates, the brief identification may be omitted.
(c) Alternative creditor procedures; consumer inquiries for clarification or documentation. The following procedures apply to creditors that treat an inquiry for clarification or documentation as a notice of a billing error, including correcting the account in accordance with § 226.13(e):
(1) Failure to disclose the information required by paragraphs (a) and (b) of this section is not a failure to comply with the regulation, provided that the creditor also maintains procedures reasonably designed to obtain and provide the information. This applies to transactions that take place outside a state, as defined in § 226.2(a)(26), whether or not the creditor maintains procedures reasonably adapted to obtain the required information.
(2) As an alternative to the brief identification for sale or nonsale credit, the creditor may disclose a number or symbol that also appears on the receipt or other credit document given to the consumer, if the number or symbol reasonably identifies that transaction with that creditor.
