Mailboxes are the most preferred locations for mounting address number signs. For 9-1-1 purposes, though, the beginning of the driveway, lane, easement, access road, etc., should also be marked. If your driveway leads to more than one address, post all numbers at the end of the driveway. Then post the correct number on each house or building. Numbers on mailboxes alone do not meet most posting requirements. Mailboxes help the postal services deliver mail, but 911 responders need to find you in an emergency! Therefore, it's important to mark all entrances and turns along the way to your home. Where access is by means of a private road and the building address cannot be viewed from the public way, a monument, pole, or other sign shall be used to identify the structure. If address numbers are placed where grass, shrubs, vines, or other plants can grow and hinder visibility, the owner must curb the growth so that the numbers are always visible. The address number sign should be posted so that it is visible from both directions of travel. 911 House numbers should be placed near the front door within a radius of the porch light and above eye level (at least 5 feet high above the grade of the roadway). Avoid placing numbers away from the front door, such as above garage doors.
