Farm Signage and Address Markers

Why do address markers matter?

Emergency crews need to find you quickly, often at night, in rain or snow, and with only a number to go on. A marker that is visible from the road in all conditions can save critical minutes. Check your marker against what the 911 center has on file, since a mismatch between the two can send crews to the wrong place.

Delivery drivers, utility workers, veterinarians and visitors also depend on them. Treat your marker as part of your emergency plan.

If you have more than one drive, buildings away from the house or a seasonal rental, each may need its own number, so ask the addressing office.

Who assigns rural addresses?

Addresses are usually assigned by the county or a local 911 or addressing office. Some places have specific rules about size, color, reflectivity and placement, and some provide the markers.

Ask your county 911 or addressing office what applies. Do not make up a number or copy one from a neighbor.

When a new road or subdivision changes addressing, the county may reassign numbers, so keep your contact information up to date with them.

What makes a good marker?

A good marker is large, simple and easy to read from a moving vehicle in poor light. Place it where responders will look, at the entrance to your driveway or lane, and keep it clear of brush and snow.

Check it each season, since weather, mowing and growth can hide it. If you have several lanes or buildings, mark each clearly.

Choose materials that hold up to sun, snow and mowing, and place the post firmly so storms do not knock it over.

• Large, high-contrast numerals
• Reflective material for night visibility
• Placed at the turn-in, facing both directions of approach
• Clear of weeds, snow and vehicles
• Repeated at a fork or at a long lane's far end

What about directions and gates?

On a farm, the address may only get responders to a road. Write simple directions for crews, including landmarks, gate codes or locks, and where to meet them. Post them near each phone and share them with family and workers. Take a photograph of your entrance and gate and keep it with your emergency information.

Tell your local dispatch center about any unusual access, such as locked gates or seasonal roads. Many will keep notes.

Add a note in your emergency plan about which way responders should approach if there are two roads.

How should you think about farm signs?

Signs can welcome customers, warn visitors of hazards, or tell trespassers to stay out. Think about what you want each sign to say and who needs to read it.

Rules for signs vary. Counties and towns may regulate size, location and lighting, and state transportation agencies control signs near highways. Ask your planning office before you build or place anything near a public road.

Sign rules also cover lights and moving or flashing signs, so check before you add anything that lights up.

What do warning and no-trespassing signs do?

Warning signs for animals, chemicals or machinery help keep people safe, and posted boundaries can help in a dispute. The wording and placement needed to be legally effective vary by state, so ask your state agency or attorney.

Keep signs clean and replace them when they fade. A sign nobody can read does nothing.

If you want to ask visitors to stay out of fields or barns, a simple sign at the gate saying so politely is often enough.

How do you keep it up?

Add markers to your seasonal checklist. After storms, mowing and snow clearing, walk the road and look at your sign as a driver would. Replace weathered numerals promptly, and keep a spare marker in the shop so a storm does not leave you without one.

Update markers if addresses change, and tell the county and anyone who sends you mail or deliveries. A short test with a friend driving by confirms that your marker works.

Ask a neighbor to tell you honestly how visible your marker is, since you see it every day and may not notice it fading.
