EMVCo has established a BIN Controller Identifier Registration (“BIN Controller ID” or “BCID”), which is a 4 character value assigned to a BIN Controller for purposes of Payment Account Reference (PAR) governance, with registration being maintained by EMVCo. The BIN Controller Identifier is included as the first 4 characters of PAR Data and uniquely identifies the BIN Controller responsible for the governance of PAR and ensuring uniqueness within the PAR ecosystem governed by that BIN Controller. The BIN Controller Identifier is intended to provide transparency of the BIN Controller that governs PAR for those BINs that are under its span of control. EMVCo does not evaluate, approve, or otherwise endorse BIN Controllers. EMVCo solely maintains a list of BIN Controllers.
