Hi everyone,
I’ve recently gotten really interested in how postal code systems work around the world, and I didn’t realize how diverse they actually are. Some countries have really detailed systems that go down to street level, while others seem to use much broader zones—or even none at all in certain areas.
I’m curious: how do people usually manage this kind of variety when dealing with global postal code data? Especially in projects or tools that rely on location lookup, shipping logistics, or anything like travel and mapping.
Also, are there any resources or databases that you’ve personally found reliable when working with international postal codes?
Would love to hear your thoughts or experiences—whether it’s for work, hobby projects, or just general curiosity like mine.
Thanks in advance!
