Searching Help

The Maricopa County Assessor's Website features an advanced, single line search engine to assist you in quickly finding what you are searching for. Using natural language queries, you can now quickly find what it is you are looking for. Our search engine will intelligently try to determine what you are searching for and return relevant results. The more information you can provide in your query, the better.

For instance, to find a parcel owned by John Doe who lives in Phoenix on Thomas Ave, you could simply type in John Doe in Phoenix on Thomas Ave or an address like 301 W. Jefferson St. Even if you aren't sure of the actual street or city the parcel resides on (or in), you could just simply type in the owner's name or the owner's name and street name. The engine will usually figure out what you are asking for without any additional effort on your part and without having to use any of the advanced search features.

Below are some tips to assist you in finding what you are looking for.

  • To find any parcel, just type in the parcel (apn) number. Any format works. For instance, [book]-[map]-[parcel][split] will work with any characters (or no characters) in between the items.
    • 111-11-111-A
    • 111.11.111.a
    • 11111111
    • 11111111a
  • To search by owner name, you can simply type in the owner's name.
  • To search by address, enter in an address in a standard "address" format. What we define as a standard format is [number] [street pre direction] [street name] [street type] [city], AZ [zip code]. You can omit city, state and zip code from queries.
    • 123 E Main St.
    • 123 East Main Street
    • 123 E. Main St. Phoenix
    • 123 Southeast Main Street Phoenix
    • 123 Main St 85001
  • To search for parcels within a subdivision, simply type in the subdivision name. You can also view all parcels within a subdivision by clicking on the subdivision name in the search results or parcel details.
  • To search for parcels within a MCR, follow the same instructions as for a subdivision. If you know the MCR number, just enter it in. You can also view all parcels within a MCR number by clicking on the MCR number link in the search results or parcel details.
  • To search for parcels within a city or zip code, use the format "cityname" [city name] or "zip" [zip code].
    • cityname Phoenix
    • zip 85003
  • To search for parcels within a section, township, and range, use the format [section-township-range]. Like a targeted parcel search, you can use any separator character you wish. The only requirement for this targeted search is that all three items; section, township and range must be present in the query.
  • To search for a business name or account number (for personal property searches), you can type in a business (account) name, address, account/roll number, multiple number, or lease number.
  • To search for mobile homes, simply type in an owner name, address, account number or a VIN.
