How it works
How to search property records by APN
Enter the APN exactly as you have it
Try the county's formatting first, including dashes or spaces. If that does not match, remove punctuation and search again.
Open the matching property record
Confirm the address, parcel number, situs details, tax context, sale history, deed details, permits, and other available property fields.
Verify with county sources when needed
For official filings, use the county links in the property records directory alongside the AssessorSearch record.
Local formats
APN and parcel number labels vary by county
County systems use different names and formats for the same core idea: a local parcel identifier.
| Common label | Where you may see it | Lookup tip |
|---|---|---|
| APN | California and many western county assessor systems | Try the number with and without dashes. |
| Parcel number | Assessor, tax, GIS, and parcel map portals nationwide | Search the full parcel number before shortening it. |
| Folio or property ID | Some Florida and county tax systems | Use the county label when comparing official sources. |
| SBL or tax map number | Some New York and northeastern record systems | Keep section, block, and lot separators if provided. |
FAQ
APN lookup questions
What is an APN number for property?
An APN is an assessor parcel number: the local identifier a county assessor uses for a parcel. Some counties call it a parcel number, property ID, tax parcel number, or folio number.
Is an APN the same as a parcel number?
Usually yes. APN and parcel number are often used interchangeably, although the exact label and format are set by the county assessor or tax office.
Can I look up an APN by address?
Yes. Search the property address first, then review the matched property record for the APN or parcel number when it is available.
Why do APN formats look different by county?
APN formats are local. Counties may use map book, block, lot, section, township, range, or tax district codes, so punctuation and digit counts vary.
