Los Angeles has neighborhood mailing address/ZIP codes, mainly in the San Fernando Valley (e.g., Van Nuys, CA; Woodland Hills, CA etc.), but it does have some outside the SF Valley as well (Pacific Palisades, CA; Venice, CA; Wilmington, CA; San Pedro, CA).

Even more confusing is when you have the mailing address of a neighboring city, like this area above Beverly Hills which is in the city of Los Angeles but has a Beverly Hills mailing address: https://goo.gl/maps/uRVwY6vgnfzo9kUd9
