BG –
The post office (Feds) determine zip code boundaries. Not the city.
They have some correlation – but not one to one – in guessing government jurisdiction.
I think you’re confusing things when you look at it strictly by zipcode.
I was curious – so I looked for a map of the city of san diego boundaries… As I said – I don’t know how accurate it is – but it seems accurate. It also roughly matches what I saw on the city website. http://www.sandiego.gov/citycouncil/
Another common mistake is to assume school districts follow city boundaries. They don’t. Parts of PQ are in PUSD. Carmel Valley is not in SDUSD even though it’s part of the city.[/quote]
UCGal, you are absolutely correct. the city of SD never annexed the area of 4S. because it had the strip of 92127 next to I-15, I think this is why BG mistook the entire 92127 for 4S.
I know the numbering convention of “921xx” to signify city of SD, but these conventions does not always fit.
City boundaries definitely do not have to follow zip codes. back in LA, people would advertise that they live in “Beverly Hill zip code” because even though they are not in BH, the fact that they shared the BH zip made their property value higher.
Quite frankly, sometimes a city doesn’t even have to be in the same county, or even the same state. Atlanta encompasses several counties, and Kansas City is in 2 states.
