Looking for information about postal databases

[OlendaCarloti]

Hello everyone,

I’ve been hearing about Postal Databases recently and I’m quite curious to understand more about them. From what I gather, they seem to be collections or systems that organize postal codes and addresses, but I’m not sure how they work exactly or what kind of information they usually include.

Does anyone here have experience with Postal Databases? How detailed are they, and are they mostly used by businesses, governments, or individuals? Also, are there any free or reliable options available for someone who wants to use them for personal or hobby purposes??

I would really appreciate any insights or recommendations. Thanks in advance!

Some free options exist, like government open-data portals (for example, the USPS provides ZIP code data in the U.S., and many countries have similar datasets). More detailed commercial databases often come with APIs or subscription services.
