Rural route
By Justin Winter · Updated August 28, 2026
An older USPS addressing format (e.g. "RR 2 Box 45") used in rural areas before many were converted to standard city-style street addresses.
Rural route addressing predates GPS-friendly city-style addresses in many low-density areas, identifying a delivery point by route and box number rather than a street name and number. USPS has converted most of these to city-style addresses over the past few decades for emergency-response and mapping reasons.
Where a rural route address is still current, it must be entered exactly as USPS has it on file — the format does not map cleanly to modern address-autocomplete tools built around street addresses.
