Area Code 773 Location: Everything You Need to Know About Chicago’s Iconic Code

When you see a phone number starting with area code 773, it’s more than just a sequence of digits—it’s a signal that the call is coming straight from the heart of Chicago, Illinois. Area codes often tell unique stories about geography, culture, and identity, and area code 773 is no exception. Whether you’re curious about where this area code is used, its history, or how it connects to Chicago’s vibrant neighborhoods, this article breaks it all down for you.

What Is Area Code 773 and Where Is It Located?

The 773 area code covers the city of Chicago, specifically the regions outside the downtown Loop. It serves the North Side, West Side, and parts of the South Side of the city. The downtown area, on the other hand, primarily uses the 312 area code.

To put it simply:

Area code 773 = Chicago neighborhoods beyond downtown
Area code 312 = Chicago’s central business district (the Loop)

This division allows for better management of phone numbers within the massive and densely populated city. So, if you receive a call from 773, it’s likely from someone living or working in one of Chicago’s famous neighborhoods such as Lincoln Park, Wrigleyville, Humboldt Park, or Englewood.

A Brief History of Area Code 773

The 773 area code was officially created in October 1996, when Chicago’s original 312 area code was split to meet the growing demand for new phone numbers.

Here’s a short timeline:

1947: Chicago was first assigned the 312 area code, covering the entire city.
1996: To avoid running out of available numbers, the city was divided — 312 remained for downtown, and 773 was introduced for outer areas.
2009: The 872 overlay was added, meaning both 773 and 872 now serve the same regions.

This change came during the rise of mobile phones, fax machines, and pagers—devices that required their own numbers. Today, both 773 and 872 coexist, ensuring Chicago residents and businesses have enough number combinations for decades to come.

Fun Fact: Why Chicago Has Multiple Area Codes

Chicago’s telecommunications growth is a reflection of its economic and population expansion. Originally, the 312 code was sufficient for the entire city. But as technology evolved—bringing in cell phones, modems, and fax machines—the demand for numbers skyrocketed.

To manage this, Chicago was split into:

312 – Downtown/Loop area
773 – Outer Chicago neighborhoods
872 – Overlay area for both regions

This structure keeps the city’s communications network running smoothly while maintaining its local identity.

How to Call a 773 Number (Nationally or Internationally)

If you’re calling a 773 number from within the U.S., simply dial:

1 + 773 + the 7-digit local number

For international calls, use the U.S. country code (+1) followed by the area code:

+1 773 xxx xxxx

Since Chicago is in the Central Time Zone (CST/CDT), always check time differences if you’re calling from abroad.
