They might. Cities can, in most states, cross county borders. Both counties and cities can have their own taxes.

I've seen cases where a neighborhood was split. Two near-identical houses, but one had less than half the property tax of the one next to it.

Believing mailing address cities actually corresponds to a unit of government is one thing I learned is incorrect when I moved to the LA area.

I live near a place called Westlake Village that straddles the LA County/Ventura County line. In LA County, Westlake Village is a city. In Ventura County, Westlake Village is a neighborhood within Thousand Oaks, and it has a different tax rate. But both mailing addresses use Westlake Village as the city.

Similarly, I have friends that live in Newbury Park, and that's what is on his mailing address. But Newbury Park is just a neighborhood within Thousand Oaks.

Mailing addresses often have little to do with local governance; they’re for the USPS. Just tells you where it will be processed.

In which case sharing the address is completely useless anyway, so the problem of having to share the address is automatically solved :)
