About Idaho ZIP codes
Idaho is home to 245 ZIP codes spanning 44 counties and 211 cities, covering one of the most geographically diverse states in the American West. All Idaho ZIP codes fall within the 832 through 838 prefix range, stretching from Pocatello in the southeast all the way to the forested panhandle towns near the Canadian border. Ada County, anchored by the booming capital city of Boise, holds the largest share of ZIP codes in the state with 32, reflecting Idaho's rapid population growth in the Treasure Valley region. Whether you're mailing to a remote wilderness outpost or a busy Boise suburb, Idaho's postal system is designed to reach every corner of this expansive and varied state.
Idaho ZIP codes all begin with 83, reflecting the state's placement within the USPS Mountain region. The second and third digits (2 through 8) further subdivide the state geographically, with lower prefixes like 832 covering the southeast near Pocatello and Boise, while higher prefixes like 837 and 838 reach into the northern panhandle near Coeur d'Alene and Sandpoint.
Ada County leads Idaho with 32 ZIP codes, which makes sense given that it contains Boise, the state's capital and most populous city, along with fast-growing suburbs like Meridian, Eagle, and Star.
Quick facts
- Idaho's ZIP codes span a range of over 600 numbers (83201–83876), reflecting the state's vast and rugged terrain that required careful postal district planning to serve remote mountain and rural communities.
- Despite having 44 counties, Idaho uses only 245 ZIP codes, meaning several rural counties share just one or two ZIP codes to cover enormous stretches of wilderness and farmland.
- The northern Idaho panhandle, which is geographically closer to Seattle than to Boise, uses 838-prefix ZIP codes that place it in a distinctly different postal zone from the rest of the state, mirroring its cultural and geographic separation.
