Yes. The property assessor parcel number, otherwise known as an APN, along with the State and County (or Parish in Louisiana, Borough in Alaska) it resides, is sufficient to begin researching real estate records and create an official title abstract. APNs are issued by local governments when an existing, larger parcel, is subdivided. Usually that is done on a county level, however it is on occasion at a city level. If you have geo-coordinates (latitude and longitude), you can use a 3rd party mapping service to covert your coordinates into an address location as well.
