Every Arizona county assessor runs a free online parcel search, and the owner's name and the tax-bill mailing address are public record. If you have the parcel number (the APN), the search takes under a minute. If you only have an address or a pin on a map, the county parcel viewer gets you the APN first. The county table is below.
The recorder is the second stop: it holds the deed, the sale date and anything recorded against the land. When the owner turns out to be an LLC or a trust, the Corporation Commission's entity search is the third.
Pick the county, open its search
The vacant-parcel count is from our March 2026 county-roll file of 502,163 vacant Arizona parcels. "LLC or trust" is the share whose owner name contains LLC or trust, which is a name match, not a legal classification. "Out of state" is the share whose tax bill goes to another state.

County quirks that trip people up
Yuma County's numbering is the biggest one. The county's own system identifies parcels by an R-number (R0056523, for instance), and the dashed book-map-parcel number you see on a tax bill, like 188-21-010, is a separate field in the county map service. If a search by the dashed number returns nothing, look for the R-number.
Yavapai's database id is a 13-digit number, not the dashed APN, so search by the dashed APN (401-01-373C, for instance) in the owner or parcel box rather than the id. Yavapai's county site also blocks automated requests, which is why we could only confirm it in a browser.
Apache's EagleWeb search shows the owner, the mailing address and the full sale history on one account page. Navajo's county map layer carries owner and mailing address and was updated the day we checked. Maricopa's county layer returns the owner, the deed number and the last sale price, and a multi-parcel sale shows the total price on every parcel, so check the deed number before reading it as a per-lot price.
Coconino's recorder is the awkward one: it searches by name, date or document number only, not by APN or address, and the portal opens behind a bot check you have to click yourself.
