Systems and methods for adapting network messaging

A non-transitory computer-readable storage medium comprising executable instructions for use in adapting network messaging, which when executed by at least one processor, cause the at least one processor to:

• receive input data indicative of a network transaction, the input data including a non-conforming account number inconsistent with a standard format for a payment network, the non-conforming account number specific to a user;
• compile a network message for the network transaction with a party specific number included in a data element of the network message reserved for a user account number and the non-conforming account number included in a different data element of the network message, wherein the party specific number is not specific to the user, wherein the party specific number includes a format consistent with the standard format for the payment network;
• and
• transmit the network message to a party associated with the party specific number.

A system for use in adapting network messaging based on input data that is inconsistent with one or more data definitions of the network messaging, the system comprising a payment network including an interface processor, the interface processor configured to:

• receive input data indicative of a network transaction, the input data including a non-conforming account number inconsistent with a standard format for a payment network, the non-conforming account number specific to a user;
• compile a network message for the network transaction with a party specific number included in a data element of the network message reserved for a user account number and the non-conforming account number in a different data element of the network message, wherein the party specific number is not specific to the user, wherein the party specific number includes a format consistent with the standard format for the payment network;
• and
• transmit the network message to a party associated with the party specific number.
