What is the 331 Area Code?
The 331 area code is a telephone area code in the North American Numbering Plan (NANP) that serves parts of the western suburbs of Chicago, Illinois. It was introduced to provide relief to the 630 area code, which was experiencing a shortage of available numbers. The 331 area code overlays the same geographic region as the 630 area code, meaning that they share the same territory.
The Introduction of the 331 Area Code
The 331 area code was officially put into service on October 7, 2007. As the population and the number of businesses in the Chicago suburbs grew, the demand for new telephone numbers increased, necessitating the introduction of a new area code to ensure a steady supply of numbers for residents and businesses.
Geographical Coverage of the 331 Area Code
The 331 area code covers several communities in the western suburbs of Chicago. Some of the major cities and towns within this area code include:
- Aurora
- Naperville
- Bolingbrook
- Wheaton
- Downers Grove
These areas are known for their vibrant communities, economic opportunities, and proximity to the city of Chicago, making them desirable places to live and work.
Why Was the 331 Area Code Introduced?
The introduction of the 331 area code was primarily driven by the exhaustion of available numbers in the 630 area code region. With the rapid growth in population and the proliferation of mobile devices, the demand for new phone numbers surged. To address this, the Illinois Commerce Commission approved the implementation of the 331 area code as an overlay, allowing existing numbers to retain their 630 area code while new numbers could be assigned the 331 code.
Impact on Local Communication
For residents and businesses in the 331 area code region, the introduction of this new code meant a shift in dialing habits. With the overlay system, ten-digit dialing became mandatory for local calls, even within the same area code. While this change initially required some adjustment, it ultimately ensured that the region could continue to grow without running into a shortage of telephone numbers.
How to Dial Within the 331 Area Code
Dialing within the 331 area code region follows the standard ten-digit dialing format, which includes the area code followed by the seven-digit phone number. Here’s how you should dial:
- For local calls within the 331 area code: Dial the 10-digit number (e.g., 331-XXX-XXXX).
- For long-distance calls: Dial 1 followed by the 10-digit number (e.g., 1-331-XXX-XXXX).
It’s important to note that the introduction of the 331 area code did not change the cost or rate of calls. Local calls remain local, and long-distance charges apply as usual.
Benefits of the 331 Area Code for Businesses
For businesses operating in the 331 area code, there are several advantages to consider:
- Increased Number Availability: The introduction of the 331 area code ensures that businesses can acquire new numbers as they expand, without the risk of running out.
- Enhanced Connectivity: With a unique area code, businesses can establish a local presence, fostering trust and accessibility with local customers.
- Flexibility in Communication: Businesses have the flexibility to choose numbers that align with their branding and marketing strategies.

As the population in the western suburbs of Chicago continues to grow, the demand for new telephone numbers is expected to persist. The 331 area code, alongside the 630 area code, will continue to play a crucial role in supporting the region’s telecommunication needs.
