In New York City, every property is assigned a unique identifier known as a Block and Lot number. This system is part of the Borough-Block-Lot (BBL) numbering system used by the Department of Finance and other city agencies for property identification and taxation.
Here’s a breakdown of the components:
Borough Code: A single-digit code representing one of the five boroughs of New York City:
Manhattan (1)Bronx (2)Brooklyn (3)Queens (4)Staten Island (5)
Block Number: A numeric identifier for a city block within the borough. Each block contains multiple lots and is typically defined by streets.
Lot Number: A numeric identifier for a specific parcel of land within a block. Each lot represents an individual property.
For example, a property in Manhattan might have a BBL number like 1-00234-0056, where “1” is the borough code for Manhattan, “00234” is the block number, and “0056” is the lot number.
This system allows for precise identification and record-keeping for each property in the city.
