The Maricopa County APN format
Eight digits in a book-map-parcel pattern, written ###-##-### — the assessor map book, the page within it, then the parcel on that page. Some parcels carry a trailing letter after a split (e.g. 301-45-678A).
The dashes are cosmetic — PlumbIntel normalizes APNs before matching, and every parcel joins to permits county-scoped, so a Maricopa County APN never resolves to another county’s parcel even when the digits collide. New to parcel numbers? Read the full APN guide.
What you get on the parcel page
- The parcel’s APN and property record
- Every building permit on record at the parcel — type, status, dates, and the contractor of record with license status
- The data source for each fact, labeled — official Maricopa County Assessor roll for parcel facts, city and county permit registers for permits
This is not the official Maricopa County Assessor site — it’s the assessor’s public roll fused with permit and sales records so the whole story reads in one place.
