The Manhattan address algorithm refers to the formulas used to estimate the closest east–west cross street for building numbers on north–south avenues in the New York City borough of Manhattan.[1][2]

AlgorithmEdit

To find the approximate number of the closest cross street, divide the building number by a divisor (generally 20) and add (or subtract) the "magic number" from the table below:
