Emergency 911 Address & House Number

House Number

Can the City of Cortland Find You Quickly in an Emergency?


The following guidelines will assist you in correctly posting an emergency 911 address number. If you have a question in reference to posting your house number, call the Fire Station at 607-758-8380, or Code Enforcement at 607-753-1741.

  • The number shall be displayed in a location visible from the road on which the number is assigned, such as a mailbox easily identifiable from the street.
  • The number should be placed on the house or dwelling unit in an area immediately adjacent to the front door. Numbers must be readily visible from the street and the view of the numbers should not be blocked by trees or shrubs.
  • Numbers may be placed on a sign or post at the entrance to a right-of-way or shared driveway. If the sign serves multiple buildings, the address to each house or unit served by that right-of-way or shared driveway shall be affixed. If the house or unit is not visible from the point at which the individual driveway breaks from the right-of-way or shared driveway, the address number must also be posted on the house or dwelling or unit.
  • Numbers should be at least 4 inches high.
  • Numbers should be plain block numerals, not script or written numbers.
  • Numbers shall be set on a background or contrasting color, preferably white or black. It is recommended that a retro reflective material be used.
  • Do not place number on utility poles, road signs, or anywhere within the road right-of-way (except mailboxes).
  • Temporary display of addresses for new structures shall be maintained during construction.
If you receive your mail at a Post Office Box, you must still post the Emergency 911 Address on your property, so that it can be located by emergency vehicles.
