VAST-2.0-ctv-universaladid-registry-format

UniversalAdId extension idRegistry should be a registry name, root domain or unknown

WarningCTV Addendum 2024IAB CTV Addendum 2024 (July 2024)VAST 2.0 and later (all versions)

Short answer

Use a registry name, a root domain such as ad-id.org, or unknown. A full URL, a domain with a path or a value containing whitespace receives a warning. The validator does not contact registries.

Why this matters in production

This rule is a strong risk signal. Tags with this issue often still parse, but they become brittle across SDKs, SSAI resolvers, and CTV environments. These rules validate supplied standardized payloads carried in legacy VAST extensions. Correct version and location handling preserves compatibility while checking ID registries, mezzanine assets, SIMID payloads and creative bindings. Optional addendum features remain optional. Affected scope: VAST 2.0 and later (all versions).
