Tools · BACnet Vendor ID Lookup
BACnet Vendor ID Lookup BACnet
Every vendor ID ASHRAE has assigned, in one filterable table — paste the number a device reports and get the manufacturer.
The Vendor ID is the
Vendor_Identifier (property 120) every BACnet device carries in its Device object and announces in its I-Am — a 16-bit number ASHRAE assigns once per manufacturer, forever.
Type a number in the decode box, or filter the full registry table by ID or company name.
Only the ID and organization are republished here; the snapshot date is under the table.
The input is seeded with an example — edit it to your number.
Input
The number a discovery log, a property sheet, or a Wireshark I-Am decode shows as Vendor_Identifier.
Output
Organization

Imported from the official ASHRAE registry — bacnet.org, assigned vendor IDs — retrieved 2026-07-08: 1629 assignments through ID 1631. IDs are assigned once and never reassigned, so a number here always identifies the same registrant — though the registry edits organization names after rebrands and acquisitions, so a name can lag this snapshot. Numbers missing from the sequence were either withdrawn or never issued, and a device reporting an ID above 1631 is newer than this snapshot. Only the ID and organization are republished — the registry's contact columns are deliberately dropped.
What a BACnet vendor ID is
A 16-bit number ASHRAE assigns to a manufacturer once and never reassigns, exposed as the Device object's Vendor_Identifier (property 120). Every device a company ships reports the same number — it identifies the maker, not the unit. Registration is free, which is why the list is long and full of names that never turn up on a job site.
The registry's first two rows are its origin story: ID 0 is ASHRAE itself, and ID 1 is NIST, which organized and hosted the earliest BACnet interoperability testing. Everything after that is the industry arriving roughly in the order it adopted BACnet.
Where you see vendor IDs in the field
Three places, usually: the I-Am a device answers during Who-Is discovery (a workstation's discovery log lists it next to the device instance), the Device object's property sheet when you pull up property 120, and the decoded I-Am APDU in a Wireshark capture. In all three it's the same bare number — which is exactly when you want this table.
It also namespaces the proprietary parts of the protocol. Object types 128–1023 and the high property numbers are vendor-specific — see the ranges on the BACnet Object Reference — so "whose device is this" is the first question when a capture shows an object type the standard doesn't define. The vendor ID answers it.
Reserved and never-assigned vendor IDs
Seven numbers — 555, 666, 777, 888, 911, 999, and 1111 — are held by ASHRAE and will never be assigned to a vendor. A device or a capture reporting one of them is running a placeholder, a test stack, or a misconfiguration, not a product from a real manufacturer.
Other holes in the sequence are registrations that were withdrawn or numbers that were never issued; because IDs are never reassigned, they stay empty forever. And since ASHRAE issues new IDs continually, a number above this snapshot's ceiling usually just means the device is newer than the table — not that it's bogus.
BACnet vendor ID FAQ
How do I find the vendor ID of a BACnet device?
Read property 120 (Vendor_Identifier) of the Device object — every workstation exposes it on the device property sheet. Devices also announce it in the I-Am they send during Who-Is discovery, so a discovery log or a packet capture shows it without touching the device. BACnet Basics covers how discovery works.
Who assigns BACnet vendor IDs?
ASHRAE, through the BACnet committee. Registration is free, normally one number per organization, and IDs are never reassigned — the number stays tied to its original registration even when the company is renamed or acquired, which is why the table shows a few "formerly" names. The official registry lives at bacnet.org.
What is vendor ID 0 in BACnet?
ASHRAE itself — the standards body took the first entry in its own registry. Vendor ID 1 is NIST, which organized and hosted the earliest BACnet interoperability testing.
Can two devices have the same BACnet vendor ID?
Yes — every device from the same manufacturer reports the same vendor ID. It identifies the maker, not the unit; the device instance number is what must be unique across the internetwork.
Which BACnet vendor IDs are reserved?
555, 666, 777, 888, 911, 999, and 1111 are set aside by ASHRAE and never assigned. If a capture or a device config shows one of these, you are looking at a placeholder or a misconfigured stack, not a real manufacturer.
