Chicago Area Codes


The Chicago Area Code 312 only covers a few square miles, making it among the smallest coverage zones in the United States. It was created in 1947 and remained the sole Area Code for Chicago until 1989. By then, the demand for more numbers had risen sharply and new Area Codes were created. You can see a list of these codes below, and click on any of them for more information.

Clicking a prefix will open a reverse phone search form with the Area Code already entered. Supply the remaining digits to start your search.

Reverse Phone Lookup With A Chicago Area Code


It’s frustrating. Sometimes we all get calls from an unknown number. And we wish there was an easy way to find out who was calling - without answering the phone. There is. A reverse phone lookup shows you who own most any land line, cell or unlisted number. It tells you who called and helps you decide whether or not you’d like to call back.
