Systems and methods are provided for identifying an account via a hash key specific to the account and presented to a third party, in connection with a network interaction. One example method includes receiving, by a computing device, from the third party, the hash key in connection with the network interaction, determining a primary account number (PAN) for the account based on the hash key, and identifying an issuer of the account based on the determined PAN. The method also includes transmitting a verification request to the issuer, to verify details of the account, and receiving a code from the issuer indicative of the verification. The method further includes intercepting an authorization request for the network interaction based on the authorization request including the hash key and, in response to the authorization request further including said code, directing the authorization request to the issuer.
