The Allocation Module sends email notifications of new transactions to the Cardholder, and all Reviewers/Allocators in his/her department, each day that one is received from the bank (multiple transactions are bundled in one email). Except in the case of in-person purchases, the department will almost always receive the email notification before delivery of the order.
Cardholder
Should log onto the Allocation Module (the link is provided in the email) and verify that he/she has made the purchase. If the merchant name or transaction are unknown, it is almost certainly fraud and the Cardholder should contact U.S. Bank immediately (view Fraud and Disputes).
Reviewer
Unless the transaction was an in-person purchase, the Reviewer does not have to do anything at this time, unless he/she suspects fraud, in which case the Cardholder should be contacted immediately.
