Buick Build Sheet by VIN — RPO Codes & Equipment

Your Buick left the factory with a list of RPO codes attached to its VIN — here is how to read it back.

What a Buick build sheet shows

Every Buick is built to a factory equipment specification recorded against its VIN — the trim line (Preferred, Essence, Avenir, ST), the RPO option codes, the wheels, and features like Bose premium audio, a panoramic moonroof or HD Surround Vision. A Buick build sheet turns those codes into a clear equipment list.

Check a used Buick before you buy

A VIN-based equipment list confirms the real trim and options, so a buyer knows exactly what's fitted and a seller can prove it — no relying on the advert.
