High Quality Content by WIKIPEDIA articles! A numbered street is a street whose name is an Ordinal number, as in Second Street or Tenth Avenue. Such forms are among the most common street names in North America, but also exist in other parts of the world, especially in the Middle East. Numbered streets were first used in Philadelphia and now exist in many major cities and small towns. Grid-based naming systems usually start at 1 (but sometimes at a higher number), and then proceed in numerical order. In the United States, seven out of the top ten most common street names are numbers, with the top three names being "2nd," "3rd," and "1st" respectively.
