Is a Call from a 515 Number a Scam?
A call from the 515 area code is not inherently a scam, as it is a legitimate geographic code for central Iowa. However, scammers can use technology to spoof any number, making it appear as if they are calling from a familiar or legitimate area code like 515 to gain your trust.
The problem is called Caller ID spoofing. Scammers based anywhere in the world can manipulate the information sent to your phone to display a 515 number. This tactic increases the chances you’ll pick up. You should judge the call by the conversation, not by the area code alone.
Red Flags for a Potential Scam Call
- Urgent Demands: The caller creates a false sense of urgency, demanding immediate payment or personal information to avoid a penalty.
- Unusual Payment Methods: They ask for payment via gift cards, wire transfers, or cryptocurrency. Legitimate organizations like the IRS or your utility company will not do this.
- Requests for Personal Data: The caller asks you to “verify” sensitive information like your Social Security number, bank account details, or passwords.
- Vague Information: They claim to be from a generic entity like “cardholder services” or “the warranty department” without naming a specific company you do business with.
How Can You Identify a Specific 515 Number?
You can often identify an unknown 515 number by using free online resources and reverse phone lookup services. These tools can sometimes connect a phone number to a specific individual or business, giving you the information you need to decide whether to call back.
Start with a simple Google search. Entering the full 10-digit number in quotes (e.g., “515-555-0123”) can reveal if the number is listed on a business website, a social media profile, or in public directories. If that doesn’t work, specialized reverse phone lookup services like Whitepages or BeenVerified may offer more details, though some advanced information might require a fee.

What is the History of the 515 Telephone Code?
The 515 area code is one of the original 86 Numbering Plan Areas (NPAs) established by AT&T and the Bell System in 1947. This makes it a foundational piece of the North American telecommunications network. Originally, it covered the entire state of Iowa in a diagonal band from the northeast to the southwest.
As Iowa’s population and demand for phone lines grew, the original 515 territory was split. In 2000, the southern and more rural portions of the 515 area were assigned the new 641 area code, leaving 515 to serve Des Moines and the central region. This change helped alleviate number exhaustion for a time.
According to the U.S. Census Bureau, the Des Moines-West Des Moines metropolitan area grew by over 18% between 2010 and 2020, a key factor driving the demand for new phone numbers.
.
Will the 515 Area Code Run Out of Numbers?
Yes, the 515 area code is projected to run out of available phone numbers, which has led to the implementation of an area code overlay. This solution adds a new area code to the same geographic region, allowing for millions of new numbers without splitting the area again.
The Iowa Utilities Board (IUB) approved the addition of the 357 area code as an overlay for the 515 territory. This means new phone customers in central Iowa may be assigned a number with a 357 area code. Existing 515 numbers will not change.
