About the 224 region
224 covers Northern suburbs in Illinois, including Algonquin, Antioch, Arlington Heights, Bannockburn and Barrington. The code has been in service since 2002.
224 itself is an overlay: it shares its territory with 847 and was introduced when those codes ran low on new number combinations. New lines may receive either code, calls between them are local, and 10-digit dialing is required across the region.

Who called me from 224?
Community reports- Caller ID is trivially spoofed: an incoming call that displays 224 does not prove the caller is really in the 224 region or even in the United States.
- Avoid calling back unknown one-ring numbers — some premium-rate scams rely on curiosity callbacks.
- Never share verification codes, payment details, or remote access during an unsolicited call, even if the caller claims to be your bank or a government agency.
- When a 224 call pressures you to act immediately, hang up and contact the organization directly through its official number.
