Standards Versions

The Register records the adoption of each version of a standard in the VIN series and the date on which it took effect. A version takes effect in the Network only when a notice of its adoption is entered here. The text of each standard, and the procedure for declaring conformance to it, are published by the Developer Portal of the Network.

Version numbers are those given by the Developer Portal. A new major version replaces the version in force; a minor version is adopted only where the adopting notice says so. No version has yet been superseded or withdrawn.

Status terms. The status of a version is one of the following.

In force
The version to which systems connected to the Network must conform. Only one version of a standard is in force at a time unless the adopting notice provides otherwise.
Superseded
A version replaced by a later version adopted by notice. A declaration of conformance to a superseded version remains valid for the period that the adopting notice allows, after which the system must conform to the version in force.
Withdrawn
A version withdrawn by notice without replacement. Systems relying on a withdrawn version must be brought into conformance with another standard, or disconnected from the Network, within the period that the withdrawing notice allows.

Transitional arrangement. Under Notice 2 (2026), a system in use on 6 September 2026 that does not conform to the versions in force may continue in use until 1 March 2027, after which it must conform or be withdrawn from the Network. Every connected system must conform to VIN-1 and VIN-5; the remaining standards apply to systems that perform the functions they describe.

A notice adopting, superseding or withdrawing a version is deposited and entered in the same way as any other notice; see How notices are published and Depositing records. Questions about an entry in this table may be sent to contact@register.gov.vin.
