I would argue a US mailing address is at least as complicated a structure, but people managed to figure out the state abbreviations and ZIP Codes fine. We just need to teach it in elementary school just like we do addresses.

Speaking of that I do wish the post office had a mail service where they issued addresses to citizens or something.

Yeah, I think digital literacy courses cover things like that, and they should.

But mailing addresses are actually extremely complicated and most people probably don't understand the full scope even of US mailing addresses. The spec is 226 pages.[0]

If you've ever had an address with any complexities beyond what is taught in elementary school (number, street, city, state, zip), you'll probably experience issues with getting others to correctly address your mail. The biggest reason this isn't a problem is because the postal service takes significant effort to deliver misaddressed mail.

whoa, I just imagined a world where USPS, Deutche Post, etc - offer domains, servers, cloud services - as a natural extension of treir previous roles..
