OpenOOH refreshes the venue taxonomy

The OpenOOH Venue Taxonomy — the standard that lets a buyer target “a salon screen” programmatically — was refreshed in early 2026 under OAAA governance. It’s a small update with an outsized point: for beauty, getting the classification right is still the single move that decides whether your inventory is found.

What changed

The taxonomy is a living standard, and the early-2026 refresh continued its incremental expansion — more venue types, clearer definitions, tighter alignment with the OpenRTB context it operates in (OAAA — primary). The OAAA framed it as advancing standardization and transparency across the programmatic DOOH supply chain. For most buyers the practical change is small; the value is that the standard keeps getting more precise and more widely adopted.

What didn’t change (and matters more)

For beauty, the important news is continuity: the Health & Beauty branch is stable. Salons remain 402 and spas 403 under parent 4, with the salon grandchildren (Unisex 40201, Men’s 40202, Women’s 40203, Nail 40204, Tanning 40205) intact. A Tattoo (404) child sits under the same parent — worth knowing if you want to include or exclude beauty-adjacent inventory. None of this requires re-tagging a correctly-classified salon network.

Why classification still decides everything

The refresh is a good moment to restate the one beauty-specific rule that the taxonomy enforces: target the child, not the parent. The spec itself says screens shouldn’t sit solely on a parent that has children — so a salon should be tagged at Salon (402), and a buy should target 402/403, not the Health & Beauty parent (4), which would also pull in gyms (401) and tattoo (404). Get this right and beauty inventory is addressable like any other DOOH; get it wrong and the contextual demand most likely to buy it never finds you. (The full mechanics — IDs, targeting rules, and the OpenRTB transport — are in the taxonomy explorer.)

The takeaway

A standards refresh is a reminder, not an emergency: the beauty branch is stable, the IDs are current, and the rule is unchanged. Use the current spec, classify your screens at Salon (402) / Spa (403) (and children where your publishers populate them), and you stay findable by the demand that matters. The standard getting steadily better is exactly the tailwind a young beauty category wants.
