I've done what you're describing here, entering a made up address is easy, it is getting payment to them without triggering fraud systems that is hard.
Many years ago US iTunes added PayPal but didn't verify that the address on the PayPal account was the same as the address on the iTunes account, so you could pay using your local billing address, but have payment go to a US iTunes fictional address. They have unfortunately closed that loophole.
I literally don't know what you're talking about with "transferring zip codes." But I was talking about your financial institution blocking the payment, not Hulu/NetFlix/whatever.
They should reject the transaction as soon as it comes in.

It's infuriating that I can't continue watching a TV show or movie just because I happened to cross a national border. For now, I use a proxy to always have access to US content, but if Netflix starts blocking that I'm going to cancel my account.
But even if that weren't true, technically it wouldn't work because people would just share their accounts with people across the border, leading to a different form of the same outcome.
The only way this would work is if you were forbidden from using your netflix account outside your home country. This would piss off a lot of travellers (like me) who consider it literally a feature that their netflix account works in other countries, and are currently using the service in a legitimate way (as we see the local content wherever we are).
