The city of Davis is divided into the following zip codes:
- 95616 — North of Interstate 80 and west of County Road 102/Pole Line Road
- 95617 — Post office boxes
- 95618 — South of Interstate 80 or east of County Road 102/Pole Line Road
Davis' zip code boundaries were re-aligned on July 1st, 2006. Previously, only El Macero used 95618. Some computer databases that generate direct mail seem to still have the 95618 zip code as being only for El Macero, and it is not uncommon for Davisites in this area code to receive mail addressed to their street address but the incorrect town name. However, the postal carriers seem to understand this, and you will generally still get your mail even if the town name is incorrect.
