About 773 Area Code
Area code 773 serves Chicago's diverse neighborhoods beyond the downtown Loop, covering Lakeview, Lincoln Park, Hyde Park, Logan Square, Wicker Park and dozens of iconic communities across the North, West and South sides. Created on October 12, 1996, as a split from the original 312 area code, it encompasses most of Chicago outside the central business district. The code supports local voice and SMS numbers used by neighborhood businesses, healthcare providers, universities and cultural institutions throughout Cook County.
The 773 region blends residential neighborhoods with commercial corridors, academic institutions (University of Chicago, DePaul University), world-class hospitals, manufacturing zones and vibrant cultural districts. From the artistic enclaves of Wicker Park and Bucktown to the historic South Side, the area represents Chicago's authentic neighborhood character. Businesses use 773 numbers for customer service, appointment scheduling, local sales and community engagement. Local numbers consistently outperform toll-free alternatives because they signal genuine connection to Chicago's neighborhood fabric rather than corporate distance.
FoneSwift displays current 773 inventory and capabilities on this page. Filter by Voice, SMS and MMS to match your communication needs. Since 773 has an overlay code (872, added in 2009), both codes serve identical geographic areas. If 773 numbers are limited, consider overlay code 872 or the downtown 312 code depending on your target market within Chicago.
If you're targeting Chicago neighborhoods, display numbers in both local and international formats (e.g., (773) 555-1234 and +1 773 555 1234) and register A2P messaging campaigns for business SMS compliance. For porting existing numbers, see our porting guide. Many Chicago businesses maintain their 773 numbers long-term because the area code carries powerful neighborhood recognition across a city where local identity matters deeply to residents and customers.

How Does Local 773 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 773 number in Chicago and Illinois, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a United States local number are:
- Country code (+1): identifies United States for international routing.
- Area code (773): directs the call to the Chicago / Illinois region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
Example formats:
| International Format (E.164) | +1 773 555 1234 |
| Local Format (National) | (773) 555-1234 |
