# Country Mapping Behavior

This section outlines how legacy country entries from **Version 1** are mapped to their updated counterparts in **Version 2**, which follows the **ISO 3166-1** standard.

The mapping ensures **backward compatibility** while aligning all current and future data with standardized country codes and names:
