How to Find Your APN Number

The assessor's parcel number, often abbreviated "APN", is a number assigned to an individual lot of land or property that is used for record keeping purposes. The numbers are assigned by either a city or county tax assessor. To locate the APN of a specific property, contact the tax assessor that has jurisdiction of the property in question. If you want to find the APN of a property currently on the market, contact the realtor handling the sale.

    Click on the section for the city or county tax assessor's office. You might be redirected to a separate website.

    Call or e-mail the tax assessor and request the property's APN. Provide the tax assessor with the address of the property. If the property in question is currently on the market, you may also contact the realtor handling the property.

  5. 5

    Locate the telephone number or e-mail address for the realtor handling the property in question. Along with the realtor's name, their phone number, e-mail address and the company they work with are often listed on the "For Sale" signs located on the property.

  6. 6

    Call the realtor and ask for the property's APN. Provide the realtor with the address of the property.
