address on BOTH sides of your mailbox using a minimum of
3-inch high white reflective numbers on a dark background.
If you live in an
area that uses community mailboxes rather
than individual mailboxes or you use a PO
Box, it is important
to display your address on your house using
a minimum of 4-inch high numbers that are
well lit and have a high contrast to the
background, both day & night. As an

First Responders try to avoid driving past
your location. Did you ever wonder how fast an
ambulance or an fire engine can travel in reverse?
