A more thorough explanation:

An assessor’s parcel number is a special number given to a piece of property, like land, by the tax assessor of the area. This number is used to keep track of the property and for tax purposes.

• 123-456-789
• 987-654-321

These numbers are examples of assessor's parcel numbers. They are unique to each piece of property and are used by the government to keep track of who owns the property and how much they owe in taxes.

For example, if you own a piece of land, the government will assign it an assessor's parcel number. This number will be used to identify your property on tax bills and other official documents.
