The 911 address contains a uniform number, the street name, direction (if applicable), and the city. The uniform number is usually assigned by the grid of the existing community. Each county usually has their own policy on how the addressing is done, but for the most part NENA guidelines are followed. These guidelines are expressed by the Master Street Address Guide (MSAG). The exact 911 addresses and associated phone numbers are put into the ALI database.
