Assessor Parcel Number

People have social security numbers, business have EINs, and properties have APN’s. An Assessor Parcel Number (APN) is a unique number assigned to each property by the government for tax collecting purposes. If you are wondering what your APN is, you can look it up by address- along with a bunch of other information in the public records at the Los Angeles County Office of the Assessor website.

APN’s in Los Angeles usually have three sets of numbers in this format:

XXXX-XXX-XXX

APN los angeles

The assessor keeps volumes of books of the plat maps of each property in the city. Here is what the corresponding book and page number looks like for the example APN:
