So many Australian sites use some data source that has an old name for the building I'm in, and sites are so convinced their address databases are right that I can't do anything about it! Mildly frustrating
Our previous apartment was listed under the wrong postcode. Annoying for Uber Eats because they would get lost.
Our current building is one of those 56-66 style buildings. Different service use a different number (e.g. postal is 56, gas is 58). We've had a few cases where our address doesn't match so the system rejects us. And when I vote I have to read which number they have upside down!
