Hi Jane, In midtown (the area between 14th Street and 59th Street) the street numbers begin east and west of Fifth Avenue. Street addresses west of Fifth Avenue are spaced 100 numbers apart between avenues; addresses east of Fifth Avenue are divided by 50 numbers between avenues, until Third Avenue when 100 numbers separate each block. Street addresses with odd numbers are always located on the north side of the street; even numbers are on the south side. Now, the Manhattan Address Locator: Crosstown Address Chart.
