No, Scottsdale is not in Phoenix. It’s a separate city, incorporated on June 25, 1951, with about 243,000 people, its own mayor and council, its own police and fire departments, its own water utility and its own sales tax. It sits against Phoenix’s northeast side, inside the metropolitan area that the Census Bureau calls Phoenix-Mesa-Chandler and that everyone who lives here calls the Valley.
So the confusion is fair. Your plane lands at Phoenix Sky Harbor, your weather app says Phoenix, and a resident asked where she’s from by a stranger in Chicago will say “Phoenix” to save ten minutes. Both answers are true at the scale they’re used. This note is about the other scale: the street you’re standing on, which is in exactly one city, or in none, and that decides who answers a 911 call, what tax lands on your hotel bill and whether “walk to Old Town” is a promise or a fiction.
What “the Valley” means
The Valley is metropolitan Phoenix, all of it: some five million people in two dozen cities and towns from Buckeye to Apache Junction. The geography is the Salt River Valley, the basin the river cut between the White Tanks and Estrellas on the west and the McDowells and Superstitions on the east. Valley of the Sun is the advertising version: a 1935 slogan a local agency wrote for the Phoenix Chamber of Commerce, because “Salt River” sold alfalfa and “Sun” sold hotel rooms to snowed-in Midwesterners. It worked, and it stuck to TV station idents and resort brochures. Locals dropped the sun and kept the Valley. Arizona as a whole isn’t “the Valley”; Flagstaff and the mountain towns are “up north,” and the Valley entry has the whole story.
Scottsdale is in the Valley the way Santa Monica is in Los Angeles: part of the metro, its own city. Whether it’s in the East Valley is a separate local argument with no winner; the East Valley entry has both sides.
Where the city line runs
Scottsdale is long and thin: about 31 miles from the Tempe line in the south to the edge of the Tonto National Forest in the north, and in the south only a few miles wide. Its borders are the reason so many addresses mislead.
- West, in the south: Phoenix and Paradise Valley. Below Camelback the Phoenix line runs roughly along 64th Street; the Arcadia neighborhood across it is Phoenix. North of Camelback, the Town of Paradise Valley wraps around Camelback and Mummy Mountains.
- West, in the north: Phoenix, along Scottsdale Road. A 1964 agreement fixed Scottsdale Road as the boundary from Cactus Road north to Jomax. East side, Scottsdale; west side, Phoenix, though both sides say Scottsdale on the mail. Kierland and Desert Ridge are Phoenix.
- East, in the south: the Salt River Pima-Maricopa Indian Community, a sovereign nation set aside in 1879, which begins at Pima Road and the Loop 101.
- East, beyond the McDowells: Fountain Hills, and in the far north Rio Verde Foothills, which is unincorporated county land.
- North: Carefree, Cave Creek and the national forest.
The map shows the districts; the layout note explains the grid that makes all of this navigable.
The addresses that say Scottsdale but aren’t
ZIP codes follow mail routes, not city limits. The post office names a ZIP for the city its station is in, so a house in Phoenix served from a Scottsdale post office gets “Scottsdale, AZ.” The ZIP code entry has the full list. The ones that matter to a visitor, with the share of each ZIP’s land inside each city from the Census Bureau’s 2020 crosswalk of ZIP areas to city limits:
- 85254, the “magic ZIP”: mostly Phoenix. About 86 percent of its land is in the city of Phoenix and 14 percent in Scottsdale. It runs from Tatum Boulevard to Scottsdale Road, Shea to about Bell. The Westin Kierland and Kierland Commons are here, in Phoenix, with Scottsdale mailing addresses. The Kierland Quarter guide covers the district, which is Scottsdale in spirit and Phoenix in law.
- 85255: mostly Scottsdale. DC Ranch, Grayhawk, Pinnacle Peak and the Princess end of town. About 58 percent of its land is inside Scottsdale, about 5 percent in Phoenix along the western edge, and the rest is undeveloped land outside any city’s limits. If you’re booking in 85255, you’re very likely in Scottsdale; check the listing’s city anyway.
- 85253: Paradise Valley. Camelback Inn, Sanctuary, Mountain Shadows, Omni Montelucia, the Hermosa Inn and the Andaz are in the town, though some of them have spent decades marketing themselves as Scottsdale. About 84 percent of the ZIP’s land is in Paradise Valley.
- 85256: the Community. Talking Stick Resort’s address is “Scottsdale, AZ 85256,” and it’s on the Salt River Pima-Maricopa Indian Community, not in any city. Salt River Fields uses a Scottsdale 85258 address and is on Community land too, and so are the Pavilions and OdySea.
- 85251, 85266: mostly Scottsdale, with Phoenix slivers on the west edge. The Phoenician is in Scottsdale; the Scottsdale Camelback Resort, a few blocks west, is in Phoenix.
The quick test: on a hotel listing, look at the city in the legal address, not the marketing name. For a house, the Maricopa County assessor’s parcel map shows the jurisdiction; the envelope never will.
Why it matters for your hotel
Taxes. Arizona’s sales tax stacks state, county and city rates, so the city line shows up at the register. Since July 2025, the combined rate on most purchases is 8.0 percent in Scottsdale (a city share of 1.70 percent) and 9.1 percent in Phoenix, which raised its city rate to 2.8 percent that month. Hotels add a city bed tax on top. The Arizona Office of Tourism’s July 2026 table puts the total tax on a room at 13.97 percent in Scottsdale, 13.07 percent in Phoenix and 13.17 percent in Paradise Valley. So the room tax is a little higher in Scottsdale, dinner and shopping a little lower. Resort fees are separate, and usually bigger; the resort fee entry explains them. The sales tax and bed tax entries have the mechanics.
Distance. “Scottsdale” on a listing can mean Old Town or it can mean Desert Ridge, fourteen-odd miles and two freeway exits apart. “Phoenix” can mean a Camelback Road resort a mile from Fashion Square. If walking to Old Town is the plan, the where-to-stay note sorts the hotels that really are walkable from the ones whose marketing is.
Police and emergencies. The city you’re in sends the police. Scottsdale Police cover Scottsdale; Phoenix Police cover Kierland; Paradise Valley has its own department; the Community has its own police and courts. In an emergency, call 911 and the dispatcher routes it; it only matters when you’re filing a report later and need to know whose it is. The public safety guide covers Scottsdale’s side.
Rules. City ordinances stop at the line. Short-term rental rules, noise rules, pool-party rules and parking rules in Old Town are Scottsdale’s; at a Kierland hotel they’re Phoenix’s, and on the Community they’re the Community’s. Casino gaming and tribal law apply on the Community side of Pima Road, which is why the casinos are there and not in Old Town.
The airport. Phoenix owns Sky Harbor, about nine miles from Old Town and the only commercial airport you’ll use. Scottsdale Airport, in the Airpark, has no airline service. The airport note covers the drive.
The enclaves, briefly
Paradise Valley incorporated on May 24, 1961, mostly so neither Phoenix nor Scottsdale could annex it, and it’s almost entirely one-acre lots and resorts. It has no town property tax and pays its way largely from resort sales and bed taxes. Plenty of things called Paradise Valley aren’t in it: the mall, the school district and the community college are in Phoenix, miles north. The Paradise Valley entry sorts them.
The Salt River Pima-Maricopa Indian Community is home to the Akimel O’odham and Xalychidom Piipaash peoples and is a sovereign government, not a suburb. It begins where Scottsdale ends and owns the casino tower visitors mistake for Scottsdale’s skyline. The Community guide explains its government; the Talking Stick district guide covers what visitors go there for.
Quick answers
Is Scottsdale in Phoenix? No. Scottsdale is a separate city, incorporated in 1951, that borders Phoenix; both are in the Phoenix metropolitan area, which locals call the Valley.
Why is Phoenix called the Valley? Because it sits in the Salt River Valley. “Valley of the Sun” was a 1935 Phoenix Chamber of Commerce advertising slogan; locals shortened it to “the Valley,” and it now means the whole metro area.
What is the Valley of the Sun? Metropolitan Phoenix: Phoenix, Scottsdale, Tempe, Mesa, Chandler, Glendale and the rest, about five million people in the Salt River Valley.
Is 85254 Scottsdale or Phoenix? Mostly Phoenix, with a Scottsdale mailing address. About 86 percent of the ZIP’s land is in the city of Phoenix, including Kierland.
Is 85255 in Scottsdale? Mostly, yes. DC Ranch, Grayhawk and Pinnacle Peak are in the city; a small strip on the western edge is Phoenix.
