The lot number is not used in all areas. This would show on your tax bill and on your deed. The tract number is sometimes called the block number. If you are unable to locate your tract number, you can leave it blank and the brokerage team will look it up as long as you provide the tax assessor parcel number (APN) or tax ID number.
The most important number is your APN. This is your tax assessor parcel number, or tax ID number. You can often find it on your tax bill, title, and the county tax assessor's website. It is the tax assessor's unique number or tax ID for the property.
