|BACnet provides facilities by which "private," i.e., non-standard, information may be transported. In order to arbitrate between non-standard messages of different manufacturers, BACnet defines a numerical "vendor identifier." Vendor IDs are available to any BACnet implementor without cost. For details on how to obtain a Vendor ID, please click here.
Vendor identifiers 555, 666, 777, 888, 911, and 999 are reserved for ASHRAE and will not be assigned to a vendor.
As of September 22, 2016, 917 Vendor IDs have been issued and are distributed internationally as shown in the following list:
