515 Area Code: A Guide to Des Moines and Central Iowa

Quick answer: Area code 515 is the telephone prefix for central Iowa, covering the state capital, its fast-growing suburbs, and the region's agricultural and financial heartland. It serves Des Moines, Ames, Ankeny, West Des Moines, Fort Dodge, and dozens of surrounding communities in the Central Time Zone, operating as a standalone code with no active overlay.

What is the 515 area code?

Area code 515 is the telephone prefix for central Iowa — a region encompassing the state capital, a flagship research university, and some of the most productive farmland in North America. One of Iowa's longest-serving codes, 515 connects a landscape where insurance headquarters, grain elevators, and university campuses share the same highway corridors.

Unlike codes in denser metros that have required companion overlays as their number pools thinned, 515 has held its central Iowa territory as a single standalone code. The 507 area code, which added the 924 overlay in August 2024 when southern Minnesota's numbers ran low, illustrates how rapid suburban growth can exhaust a single-code capacity that Iowa's more measured expansion has not.

Cities and counties in the 515 area code

The 515 coverage area spans the heart of Iowa, centered on the Des Moines metro and radiating outward through a ring of fast-growing suburbs into the prairie towns and agricultural counties beyond. Des Moines sits at the geographic core, where the Des Moines and Raccoon rivers converge, and the metro has expanded steadily in every direction — making Ankeny and Waukee among the fastest-growing cities in the entire Midwest.

Major cities and communities in the 515 area:

• Des Moines — Iowa's capital and largest city; the hub of state government, insurance, financial services, and a growing technology sector centered on the Principal Park and East Village corridors
• Ames — Home to Iowa State University, a Big 12 research institution with more than 30,000 students that drives both the local economy and a statewide talent pipeline in engineering, agriculture, and business
• Ankeny — One of the fastest-growing cities in Iowa and the broader Midwest, a northern Des Moines suburb with a strong retail, logistics, and light-manufacturing base
• West Des Moines — A major commercial and financial-services hub on the metro's western edge, home to regional offices of some of the nation's leading insurance and investment companies
• Urbandale — A thriving western suburb with insurance, technology, and professional-services employers clustered along the I-35/80 corridor
• Fort Dodge — A regional commercial center to the north of Des Moines, serving the agricultural and manufacturing communities of Webster County
• Waukee — A fast-growing western suburb that has attracted large employers, a major Apple data center campus, and significant distribution infrastructure

Counties within the 515 service territory:

The entire 515 coverage area observes Central Time (UTC−6 in winter, UTC−5 during DST). When scheduling calls with partners in Eastern Time cities such as New York or Atlanta, account for the one-hour difference; a 9 a.m. New York call lands at 8 a.m. in Des Moines.

A short history of the 515 area code

Area code 515 was assigned to Iowa as part of the original North American Numbering Plan in 1947, when the continent's telephone network was first divided into geographic codes. Iowa was organized into two original codes: 515 for the western and central portions of the state including Des Moines, and 319 for the eastern half centered on Cedar Rapids and Iowa City.

For decades, 515 served a broad swath of Iowa's midsection — from the Missouri border in the south to the Minnesota border in the north. As mobile phones, internet services, and business lines multiplied through the 1980s and 1990s, that territory needed to be refined to preserve number capacity.

In 1997, area code 641 was carved out of the former 515 footprint to serve north-central and south-central Iowa communities outside the Des Moines metro, leaving 515 concentrated on the capital region and its surrounding counties.

The Iowa Utilities Board oversees telephone numbering in the state alongside the North American Numbering Plan Administration, monitoring 515's available number pool as the Des Moines metro continues its sustained growth. Despite that growth, 515 has remained a standalone code with no overlay introduced in its nearly eight decades of service.

Key milestones:

• 1947 — 515 created as one of Iowa's original area codes, assigned to central and western Iowa including Des Moines
• 1997 — Area code 641 split off from 515 to serve north-central and south-central Iowa communities outside the Des Moines metro
• Present — 515 remains a standalone code with no active overlay, continuing to serve Iowa's capital region and its surrounding counties

Calling a 515 number

Because 515 operates without an overlay, the Des Moines area has not been subject to mandatory ten-digit dialing in the way that overlay regions are. Even so, saving every contact with the full ten-digit format is the reliable standard that connects every call from any phone or carrier, and it is the format you should store for every 515 number.

Time zone tip: Des Moines observes Central Time — one hour behind Eastern Time cities like New York and Atlanta, one hour ahead of Mountain Time, and two hours ahead of Pacific Time. A 10 a.m. conference call from Chicago lands at the same local time; a 10 a.m. Los Angeles call arrives at noon in Des Moines.

Why a 515 number is good for business

Des Moines consistently ranks among the top cities in the United States for business climate, cost of living, and financial services — and a local 515 number signals genuine Iowa presence to customers who value dealing with a recognizable local prefix. In a region where local credibility still drives purchasing decisions, a 515 area code carries more community trust than a toll-free or out-of-state number from the first ring.

Reasons to choose a 515 area code number:

• Insurance and financial services — Des Moines is one of the leading insurance capitals in North America, home to Principal Financial Group, EMC Insurance, and dozens of regional carriers and brokerages that collectively employ tens of thousands across the metro
• Agriculture and agribusiness — Iowa is the nation's top corn and pork producer, and central Iowa hosts major seed companies, grain cooperatives, agricultural lenders, and crop-input suppliers serving producers throughout the Corn Belt
• Healthcare — UnityPoint Health, Mercy Medical Center, and an expanding network of allied medical providers anchor a substantial healthcare sector serving both the Des Moines metro and the broader central Iowa region
• Education and talent — Iowa State University in Ames feeds a consistent pipeline of engineering, business, and agricultural graduates into the central Iowa economy, giving employers in the 515 region reliable access to skilled local talent
• Virtual reach — Just as a virtual 508 area code number lets businesses reach southeastern Massachusetts customers from any location, a virtual 515 number routes calls to any device and gives any business a genuine Des Moines presence without a physical Iowa office

515 area code scam calls to watch for

Because 515 is immediately recognized as a Des Moines and central Iowa number, scammers spoof it to appear local to residents who regularly receive calls from state agencies, farm lenders, utilities, and healthcare networks. Neighbor spoofing — displaying a 515 prefix that matches a caller's own exchange — is especially effective in communities where trust in familiar local numbers runs high.

Common 515 scam types to watch for:

• IRS and tax fraud — Callers impersonating IRS agents and threatening arrest over unpaid taxes, a high-pressure tactic frequently targeting small-business owners and farm operators during and after tax season
• Agricultural and farm-input fraud — Scammers posing as seed dealers, grain buyers, or equipment representatives to extract upfront payments or banking information from Iowa farm operators across the region
• Utility shutoff threats — Fraudsters impersonating MidAmerican Energy or Alliant Energy representatives, demanding same-day payment to prevent electricity or natural gas disconnection
• Social Security suspension fraud — Automated calls claiming a Social Security number has been suspended due to suspicious activity, frequently targeting older residents in smaller central Iowa communities
• Financial services and loan fraud — Callers posing as bank representatives, mortgage servicers, or student loan administrators to capture account credentials or personal financial information from consumers

How to protect yourself:

• Let unknown 515 calls go to voicemail and verify the caller independently before responding
• No government agency, utility, or financial institution will ever demand payment by gift card, wire transfer, or cryptocurrency during an unsolicited call
• Confirm any organization through the contact details listed on its official website
• Report suspected 515 scam calls to the FTC at reportfraud.ftc.gov
