Address Numbers

In most of St. Clair County, we use a measured system to determine your address number. There are 1,000 numbers in each mile, or one address each 5.28 feet (a mile is 5,280 feet). This system is very easy to use for emergency responders, mail and delivery services.

Examples of Addresses
If the distance to your home from the starting point of the road is X, then your address = Y.
Distance = Address #
52 Feet

100 Feet

528 Feet (1/10 of a Mile)

You can see that an address number can easily be "decoded" by anyone looking for a specific address. Even numbers are on the right and odd numbers are on the left if you are traveling in the same direction the numbers are assigned. When the fire department hears an address of 5750, they know it is 5-3/4 miles from the starting point, on the right, to this address.
