Thanks for posting your question in the Microsoft Q&A forum.

In Azure Maps API, the "Postal Code" and "Extended Postal Code" represent different levels of granularity in the postal code information. The specific usage may depend on the country or region, and it's essential to understand the differences between them.

1. Postal Code: The "Postal Code" typically refers to the primary postal code or ZIP code for a given area. It's the primary code used for sorting and delivering mail. In many countries, this is the standard postal code that most addresses will share.
2. Extended Postal Code: The "Extended Postal Code" may represent a more detailed or specific portion within the main postal code. It might provide additional information, such as a street block or a specific building within a larger postal zone. However, not all countries or regions use an extended postal code, and in some cases, this field might be empty.
