A consumer requests a wire entirely by phone from their account at our Bank, and the wire is a remittance transfer under Reg E.
Are we required to provide the receipt on or with the periodic statement, or can we mail the receipt the same day that the transaction is finalized?

"If a transaction is conducted entirely by telephone, a receipt required by paragraph (b)(2) of this section may be mailed or delivered to the sender no later than one business day after the date on which payment is made for the remittance transfer. If a transaction is conducted entirely by telephone and involves the transfer of funds from the sender's account held by the provider, the receipt required by paragraph (b)(2) of this section may be provided on or with the next regularly scheduled periodic statement for that account or within 30 days after payment is made for the remittance transfer if a periodic statement is not provided."

The delayed provision of the receipt is an OPTION if the customer will receive a statement on his account within the next 30 days. You don't have to wait until then. You can deliver it by mail if you place it in the mail by the business day after payment is made by the consumer for the transfer.
