It fails in the other direction in Canada, where a specific postal code works like a 9+4 zip code, in that it might identify one side of one block of a street, so it doesn't give you much additional privacy through precision loss anyway.
- gabereiser 3y agoThe US does that too in most places. 5+4 zip codes. It's still not enough and suffers the same precision issues and we (the USA) are woefully ill-prepared for the housing build out boom that will happen in the next decade. We need a better system. We will exhaust our zip codes like we have our IPv4 addresses.
- wlonkly 3y agoOops, right, 5+4, not 9+4. Counting is hard. But yeah, what I meant to express was that Canada doesn't have a lower-precision version in regular use.
- bombcar 3y agoZip codes don't need to identify buildings, they need to identify post offices (and with +4, mail carrier routes). That's a much smaller number.
