Frequently Asked Questions
- Which school district serves Walnut?
- Mostly Walnut Valley Unified, though Rowland Unified serves part of the city. District boundaries do not follow the city line, so confirm the assigned schools for a specific address rather than relying on the city name.
- What ZIP code covers Walnut?
- 91789, which Walnut shares with Diamond Bar. Walnut holds about 81% of that ZIP's residential parcels and Diamond Bar the remainder, so a ZIP code alone does not establish which city a home is in.
