To get an address for vacant land, contact the county office that assigns addresses (usually the 911 addressing coordinator, planning department, or public works office), submit an application with a site plan and proof of ownership, and identify the access point where the address will be posted. The catch: many counties only assign addresses tied to development activity, so if you have no building permit or site plan in motion, you may need to wait or ask about a rural ID number that identifies the property without functioning as a permit-ready address.
Who Actually Assigns the Address
There is no national office for this. Street addresses are handed out by local government, at the county level for unincorporated land and at the city level for land inside municipal boundaries.
In most counties, the 911 addressing coordinator handles new assignments. That coordinator usually sits within the emergency management or public safety department, calculates the number based on your property’s position along the road, records GPS data for the location, and enters the address into the emergency dispatch system. In other counties the same work happens in the planning department or public works office. If you don’t know which applies to you, call the main county line or search the county website for “911 addressing” or “new address request.”
If your land sits inside city limits, the city’s planning or engineering department controls the assignment instead. Where a parcel straddles a city boundary, confirm jurisdiction before you apply, because submitting to the wrong office wastes time.
Will the County Assign an Address to Your Vacant Parcel?
This is the question that stops most landowners, and the answer is entirely county-specific. Most jurisdictions assign addresses as part of the subdivision plat approval or building permit process. In practical terms, an address is typically issued once you’ve filed for a building permit, submitted a site plan, or recorded a subdivision plat. A 911 address often has to be assigned before permits can be issued, and a permanent address has to be posted before a final inspection.
If you own a vacant parcel with no immediate construction plans, some counties will not assign a street address at all. Others will assign one when an addressing official determines it’s appropriate. Some offer a “rural ID,” an identifier that works for locating the property but isn’t valid for permits. Call the addressing authority early and ask directly what they’ll issue for undeveloped land.
Even where a county is willing to assign an address without construction, they generally need an identifiable access point: a driveway, gate, or clear road frontage where the address marker can be posted. The number itself is calculated by distance from a reference point along the road, with even numbers on one side and odd on the other.
What to Submit
Application procedures vary, but the pattern is consistent. Contact the addressing authority and request an application. Many counties now run online portals; some still take requests by phone or in person.
Most offices want the following:
- A site plan or survey showing parcel boundaries, any planned structure, and the driveway or access point connecting to the road.
- Proof of ownership, usually a copy of the deed, or a letter of authorization if someone is submitting on the owner’s behalf.
- A building permit receipt or application, in counties that tie addressing to permits.
- Location details, including the road the property fronts on, neighboring addresses, and the position of the driveway or gate. In rural areas, expect the coordinator to visit the site and record GPS data before assigning a number.
Timing and Cost
Simple residential requests are usually reviewed within about three business days. More complex situations run longer. Multi-family projects that require new street names can stretch to 30 days or more, because street name petitions may need separate approval.
Application fees typically fall between $20 and $130, and some counties charge nothing. If your parcel also needs a driveway or entrance permit before the address can be assigned, that adds roughly $175 to $440 depending on the jurisdiction.
Getting the Address Recognized by USPS
A county-assigned address doesn’t automatically mean mail will arrive there. The local government is supposed to report new addresses to USPS Address Management for inclusion in delivery routes, and in rural areas or during rapid growth that reporting sometimes fails to happen.
Allow five to seven business days after the county assigns your address, then check the USPS.com ZIP Code Lookup Tool. If your address appears with a nine-digit ZIP code, it’s in the system. If it doesn’t, you have two ways to fix it: report the address to your local post office directly, or submit the online Growth Management Assistance Request form through USPS. Developers bringing multiple new addresses online should ask for a USPS Growth Coordinator through that same form.
Setting Up Utilities
Utility connections are a separate track. Water, electric, and gas providers each need the formal street address to open a new service account, and some won’t schedule a connection until the address is verified in their internal systems. Contact each provider as soon as the county assigns your address so the paperwork moves in parallel with anything else you’re doing on site.
Posting the Address After Assignment
Once an address is assigned, most jurisdictions require you to post it visibly at the road. Fire codes in many areas mandate reflective address signs so responders can find the property at night or in poor visibility. Typical rules call for numbers at least four inches tall with a half-inch stroke width on a contrasting background, mounted on a post or monument visible from the road. Double-sided signs are standard on single-lane roads. A basic reflective sign runs $10 to $30, and some counties sell them through the addressing office or fire department.
For properties on private roads or set far back, requirements are stricter. You may need an additional sign at the intersection of the private and public roads, plus another at the driveway entrance. Post the sign promptly. In many jurisdictions the final building inspection cannot be completed until the address is permanently displayed.
Identifying Your Land Before You Have an Address
If you can’t get a street address yet, your parcel still has several identifiers you can use for legal, tax, and practical purposes.
Parcel Number
Every taxable parcel has a Parcel Identification Number (PIN), also called an Assessor’s Parcel Number (APN) or Tax ID. The county assessor assigns it, and it’s the primary way the government tracks your property for tax assessment and ownership. Every parcel in the county’s database has one, even parcels with no physical address. You can look it up through the assessor’s office in person, by phone, or through their website using the owner’s name or a general location.
Legal Description
The legal description defines the exact boundaries of the property and is what deeds, title documents, and closing paperwork rely on. When vacant land changes hands, it’s the legal description copied from the deed that ensures the correct parcel transfers, not any street address. Common formats include metes and bounds, lot and block, and the rectangular survey system using townships, ranges, and sections. You can pull the legal description from deed records at the county recorder’s or clerk’s office.
GPS Coordinates
Latitude and longitude values pinpoint a specific spot and work well for directing contractors, meeting a surveyor, or giving anyone directions to the parcel. GPS coordinates don’t carry the legal weight of a parcel number or legal description, but they’re universally understood and require no government assignment. Any mapping app will produce them when you drop a pin.
Plus Codes and what3words
Two digital systems offer a practical workaround for sharing a location without a street address. Google Plus Codes (Open Location Codes) assign a short alphanumeric code to every roughly 14-by-14-meter area on earth; drop a pin in Google Maps and the code appears. The what3words system divides the globe into 10-foot squares and gives each one a unique three-word combination. Emergency services in parts of the United States have adopted what3words as a supplemental tool for locating callers in areas without street addresses, including parks, trails, and rural land.
Neither system replaces a government-assigned street address for legal, tax, or permit purposes. For telling a delivery driver or a contractor exactly where your land is, they work immediately and cost nothing.
