Disclosed are exemplary embodiments of systems and methods for facilitating services associated with transaction requests. In an exemplary embodiment, a method generally includes receiving, from a first entity, a transaction request for a payment account transaction. The transaction request includes a primary account number (PAN) for a payment account involved in the transaction. The exemplary method also includes overwriting the PAN in the transaction request with a non-PAN identifier (NPI), where a first segment of the PAN is identical to a first segment of the NPI and where the NPI is an invalid PAN. The exemplary method further includes routing the transaction request to a service, whereby the service is able to be implemented for the transaction request based, in part, on the first segment of the NPI while the PAN remains anonymous to the service.
