Regionalization is a feature of VTEX Intelligent Search that allows for the optimization of search results according to the availability of sellers in the customer's region.

Regionalization uses a behavior from VTEX Intelligent Search called Availability. It searches for products available in the inventory of sellers that serve a particular region.

Stores that have more than one registered white label seller usually have specific inventories for each region. This is the case for supermarkets, for example.

With the Regionalization feature enabled, if a customer enters their Postal Code while browsing the store (before checkout), only products available in the corresponding region will be displayed in the search results.
