Arizona ZIP Code Lookup & Directory
A package addressed to downtown Phoenix and one headed to a home on the Navajo Nation near Window Rock might both carry an 86xxx or 85xxx prefix, but the delivery experience behind those two ZIP codes couldn't be more different. Phoenix, Tucson, Mesa, and Scottsdale sit inside some of the densest ZIP coverage in the Southwest, while huge stretches of northern and western Arizona rely on a single ZIP code to cover thousands of square miles of desert, mesa, and tribal land. Getting the code right matters just as much for a same-day Phoenix delivery as it does for mail reaching a remote community outside Tuba City.
This directory is built to make that lookup fast whether someone is confirming a Maricopa County address, checking which ZIP covers a growing Pinal County suburb, or verifying a delivery point on tribal land where street addressing works differently than in the cities. For ZIP systems in other states, see the Alabama ZIP Code Directory and the Alaska ZIP Code Directory.
About ZIP Codes in Arizona
Arizona ZIP codes begin with either 85 or 86, running from around 85001 in downtown Phoenix up to 86556 near the Navajo community of Navajo, Arizona. The state uses a dozen three-digit prefixes in total, and the split between them is geographic: 850 through 853 cover central and southern Arizona, including Phoenix, Tucson, and the fast-growing corridor along I-10, while prefixes from 855 up through 865 shift toward the northern high country, covering Flagstaff, Sedona, and the vast Navajo and Hopi reservation lands.
Maricopa County, home to Phoenix, accounts for by far the largest share of the state's ZIP codes, a direct result of the metro area's rapid suburban sprawl over the past three decades. Pima County, anchored by Tucson, comes in second, and Pinal County the corridor stretching between Phoenix and Tucson through towns like Casa Grande and Florence ranks third and continues adding ZIP codes as new master-planned communities get built out.
How ZIP Codes Work in Arizona
USPS assigns a preferred city name to every Arizona ZIP code, and in the Phoenix metro area this creates constant confusion. A ZIP code technically labeled "Phoenix" might actually deliver to Ahwatukee, Laveen, or unincorporated Maricopa County land, since USPS routing follows carrier efficiency rather than city limits. The same pattern shows up around Tucson, where ZIP codes bleed into unincorporated Pima County communities like Vail and Catalina.
Tribal land adds another layer. The Navajo Nation, the largest reservation in the country, spans parts of three states and uses its own set of Arizona ZIP codes centered on communities like Window Rock, Chinle, and Kayenta. The Tohono O'odham Nation southwest of Tucson and the Gila River Indian Community south of Phoenix each have dedicated ZIP codes as well, and many addresses on these lands use PO Box or rural route delivery rather than standard street addressing.
Downtown Phoenix and downtown Tucson both carry ZIP codes reserved mostly for PO Boxes and business mail, separate from the residential codes covering their surrounding neighborhoods.
Browse ZIP Codes by City
City search works well across Arizona's roughly 140 incorporated cities and towns. Searching a mid-size city like Yuma, Prescott, or Sierra Vista returns a handful of results, while larger metros return dozens. Phoenix alone returns more individual ZIP codes than any other city in the state, split across downtown, midtown, north Phoenix, west Phoenix, and the Ahwatukee area in the south.
Major Cities & ZIP Code Coverage
Phoenix, the state capital and largest city, carries more than 60 individual ZIP codes. Downtown sits under 85003 and 85004, the midtown and Camelback corridor runs through 85012 to 85016, north Phoenix covers 85020 to 85024, and south Phoenix and Ahwatukee fall under 85040 to 85048.
Tucson, Arizona's second-largest city, spans ZIP codes from roughly 85701 through 85775. The historic downtown and the University of Arizona area near 85705 carry some of the highest ZIP density outside Phoenix, reflecting the mix of student housing and older residential neighborhoods.
Mesa, one of the largest suburbs in the Phoenix metro, and Chandler, home to major semiconductor manufacturing, both carry their own dense ZIP clusters distinct from Phoenix proper, reflecting how thoroughly built-out the East Valley has become.
Scottsdale splits into several ZIP codes covering Old Town, the resort corridor along Camelback Mountain, and the more rural northern reaches near the McDowell Mountains.
Flagstaff, the main city of northern Arizona, uses 860xx codes and functions as the postal and logistics hub for the surrounding Coconino County, including nearby Sedona and the South Rim of the Grand Canyon.
ZIP Codes by County
Maricopa County dwarfs every other county in ZIP code count, a reflection of Phoenix's status as one of the fastest-growing metro areas in the country. Pima County follows at a distance, and Pinal County has been closing the gap as Phoenix's suburban growth pushes south along the I-10 and US-60 corridors into towns like Maricopa and Eloy.
Rural and reservation-heavy counties tell the opposite story. Apache County and Navajo County, which together cover most of the Navajo Nation and the Hopi Reservation, have relatively few ZIP codes given their size, with each one often serving a large, sparsely connected area rather than a compact town.
Popular ZIP Codes
| ZIP Code | City | County | Notes |
|---|---|---|---|
| 85003 | Phoenix | Maricopa | Downtown core, government and business district |
| 85701 | Tucson | Pima | Historic downtown Tucson |
| 85281 | Tempe | Maricopa | Arizona State University area |
| 85338 | Goodyear | Maricopa | Fast-growing West Valley suburb |
| 86001 | Flagstaff | Coconino | Gateway to the Grand Canyon South Rim |
| 86515 | Window Rock | Apache | Navajo Nation capital |
| 85364 | Yuma | Yuma | Winter agriculture hub near the border |
| 85635 | Sierra Vista | Cochise | Near Fort Huachuca military installation |
Mailing, Shipping & Address Verification
Arizona's fastest-growing suburbs cause the most address confusion. New developments in Buckeye, Queen Creek, and San Tan Valley sometimes get assigned a ZIP code carrying a neighboring city's preferred name before local infrastructure catches up, so it's worth confirming the ZIP against the actual delivery point rather than the city printed on a map. On tribal land, many addresses rely on PO Box or rural route numbers rather than a conventional street address, and verifying these before shipping helps avoid delays common to standard parcel services that expect a physical street number.
Snowbird populations add another wrinkle: cities like Yuma and parts of the Phoenix metro see huge seasonal population swings each winter, and mail volume through those ZIP codes fluctuates accordingly, which can affect delivery timing during peak season.
Business, Logistics & Delivery
Interstate 10 forms Arizona's main east-west freight spine, connecting Phoenix and Tucson before continuing to California and New Mexico. Interstate 17 runs north from Phoenix to Flagstaff, while I-8 links Phoenix to Yuma and on to San Diego, and I-19 connects Tucson to the Nogales border crossing, one of the busiest commercial ports of entry on the US-Mexico border.
Phoenix Sky Harbor International Airport is one of the busiest cargo and passenger airports in the Southwest, anchoring logistics for the semiconductor and aerospace industries including Intel's manufacturing campus in Chandler, TSMC's new fabrication plant near Phoenix, and Honeywell's aerospace operations. Tucson International Airport supports similar traffic for southern Arizona's defense and aerospace sector, including Raytheon Missiles & Defense.
Yuma County's agricultural ZIP codes see enormous freight volume each winter, since the region supplies a large share of the country's leafy greens during the cooler months. Copper mining around Globe, Superior, and Bisbee still drives freight through certain rural ZIP codes in the southeast part of the state, while border-crossing freight through Nogales keeps ZIP codes along I-19 busy with cross-border trucking traffic year-round.

Helpful Tips
Double-check ZIP codes in newer Phoenix-area suburbs, since rapid development sometimes outpaces how quickly a community gets its own distinct postal designation. When mailing to tribal communities, use PO Box or rural route information exactly as given rather than trying to construct a standard street address. Remember that Arizona doesn't observe daylight saving time statewide except on the Navajo Nation, which does so shipping deadlines tied to time zones need an extra check during the summer months. For deliveries to Yuma or other agricultural areas during winter, plan for higher shipping volume and potential delays tied to the seasonal population increase.
