Region Lock – Hide States & Provinces at Checkout for WooCommerce

By default WooCommerce lets a customer pick ANY state/province of a country you sell to — even regions you have no shipping method for. They get all the way to checkout, see “no shipping method available for your address”, and abandon the order.

Region Lock removes the regions you choose from WooCommerce’s address dropdowns, so customers can’t select them in the first place. Set the regions once, per country, for any country you sell to — no code, no theme edits.

Features

• Pick the exact states/provinces to hide, grouped by the countries you sell to.
• Works for any WooCommerce country that has states/provinces (Spain’s Canary Islands, US states, Italian provinces, and so on).
• Searchable region picker built into a clean admin screen.
• Safe by design: if you later stop selling to a country, stored regions for it are ignored — nothing breaks.
• Part of the Extova plugin family — one clean “Extova” menu in your sidebar.
