Random Address in Colorado

Pick a number from 1 to 15 and press Generate Address to get that many Colorado addresses, each on its own card in the form 8442 Everett Way, Arvada CO 80005. This is a smaller and more literal list than most of the state tools on this site: 230 entries with real street names and correctly matched ZIP codes, but weighted heavily toward one Denver suburb. It's fine for a convincing test record; for statewide coverage, read what's in the list first.

What you can control

One input, the count, from 1 to 15 per run. There's no city, county or ZIP filter. Each run shuffles all 230 entries and returns the first ones off the pile, and every card has a copy icon that puts the full line on your clipboard.

What's actually in the list

Of the 230 addresses, 189 are in Arvada, the suburb northwest of Denver, with ZIPs 80002 through 80007 and 80403. The street names there are real Arvada streets such as Everett Way, Yarrow Street, Kipling Parkway, Simms Street and West 64th Avenue. The remaining 41 entries are scattered across about a dozen other places:

• Front Range cities: Boulder (80304), Fort Collins (80521), Greeley, Aurora (80011–80012), Littleton, Westminster and Wheat Ridge.
• Southern Colorado: Pueblo (81006).
• Western Slope and mountain towns: Grand Junction (81504), Palisade (81526), Telluride and Mountain Village (81435), and Aspen (81611).

Denver proper and Colorado Springs are not in the list, so this tool won't hand you a downtown Denver address. What it gives you instead is addresses that hold up under scrutiny: the ZIP matches the city, and the street exists.

What each card shows

A street number, street name, city, the abbreviation CO and a five-digit ZIP, written as one line without a comma before the state. There's no name, unit number or phone. For addresses across all 50 states, the Random US Address Generator covers the whole country.

Practical uses

• Address validation tests. Because street, city and ZIP are coherent, these lines pass stricter checks than randomly assembled addresses. Use them to confirm your validator accepts good Colorado input.
• Shipping and tax zone tests. Colorado's sales tax varies by city and special district. An Arvada address and a Pueblo address should produce different rates, which makes a handy pair for checking your logic.

Colorado address and ZIP code format

Colorado ZIP codes run from 80001 to 81658 and all begin with 80 or 81. The 800–802 block covers the Denver metro area: Arvada and Westminster in 8000x, Aurora in 8001x, Littleton in 8012x and Denver itself in 802xx. Boulder and Longmont sit in 803, Fort Collins and Loveland in 805, Greeley in 806, Colorado Springs in 809, Pueblo in 810, and the Western Slope towns from Grand Junction to Telluride in 814–816.

Denver-area street names follow a grid: numbered avenues like West 64th Avenue run east-west and count up from downtown Denver, while named north-south streets in Jefferson County (Everett, Kipling, Simms, Yarrow) run in alphabetical sequence heading west. That's why so many of the Arvada entries look alike.
