Where is the 515 Area Code Located?
The 515 area code is geographically centered in the state of Iowa, covering the state capital, Des Moines, and its surrounding metropolitan and rural areas. This region serves as Iowa’s economic, political, and cultural hub. It encompasses a significant portion of the state’s population and major institutions.
Beyond the urban center of Des Moines, the 515 area extends to include Ames, home to Iowa State University, a major research institution. The area is characterized by a mix of urban development, suburban communities, and rich agricultural land, reflecting the broader identity of the state. If you receive a call from a 515 number, it is originating from this core central Iowa region.

What is the History and Future of the 515 Area Code?
The 515 area code is one of the original 86 area codes created by AT&T and the Bell System in 1947 as part of the North American Numbering Plan (NANP). Initially, it covered the entire eastern portion of Iowa. However, population growth and increased demand for phone lines, especially with the rise of pagers and fax machines, led to several splits.
In 1997, the southeastern portion was split off to form the 319 area code. More significantly, in 2000, most of the original 515 territory was reassigned to the new 641 area code, leaving 515 to serve a concentrated area around Des Moines and Ames. The future of 515 is stable for now, but like many urban area codes, the possibility of an overlay (a new area code added to the same geographic region) exists to accommodate future growth.
Which Major Cities and Counties Use the 515 Area Code?
The 515 area code is anchored by Des Moines and includes several other significant cities and counties that are vital to the region’s economy and culture. The primary counties served are Polk, Story, Dallas, Boone, and parts of several others. This concentration ensures that a 515 number is strongly associated with the central Iowa power base.
The table below highlights some of the most prominent locations within the 515 area code.

What Time Zone Does the 515 Area Code Use?
All phone numbers within the 515 area code are located in the Central Time Zone (CT). This is an important detail for anyone scheduling calls or meetings with individuals or businesses in this region. The Central Time Zone is six hours behind Coordinated Universal Time (UTC-6).
During Daylight Saving Time, which runs from the second Sunday in March to the first Sunday in November, the area observes Central Daylight Time (CDT), which is five hours behind UTC (UTC-5). When placing a call, always confirm the current time in Des Moines to avoid calling outside of business hours. For example, if you are in the Pacific Time Zone, central Iowa is two hours ahead of you.
According to the U.S. Census Bureau’s 2023 estimates, the Des Moines-West Des Moines metropolitan statistical area has a population of over 737,000 residents, all of whom reside within the 515 area code.
How Do I Get a 515 Area Code Phone Number in 2026?
In 2026, obtaining a 515 area code phone number is straightforward and can be done through mobile carriers or Voice over IP (VoIP) providers. Traditional landlines are less common, but the process for acquiring a number remains similar across different technologies. You must provide proof of residence or a business address within the 515 geographic area for most services.
Major mobile carriers like Verizon, AT&T, and T-Mobile offer 515 numbers for new lines of service. For businesses or individuals needing a local presence without a physical office, VoIP services such as Google Voice, Ooma, or RingCentral are excellent options. These services allow you to select a 515 number that can be forwarded to any phone, anywhere in the world.

Is the 515 Area Code Running Out of Numbers?
Currently, the 515 area code is not in immediate danger of number exhaustion, but the situation is monitored closely. The entity responsible for this is the North American Numbering Plan Administrator (NANPA). NANPA projects the lifespan of area codes based on the rate at which new numbers are assigned.
The rise of mobile devices, IoT (Internet of Things) devices, and business phone systems has accelerated number consumption in many urban areas. While the 2000 split that created the 641 area code provided significant relief, continued population and economic growth in the Des Moines metro will eventually require a solution. The most common solution is an overlay, where a new area code is added to the same geographic area, requiring 10-digit dialing for all local calls.
