Geographic Coverage & Key Cities

It spans several counties in Chicago's western suburbs, with DuPage County forming its core. The 630 territory extends through southern Kane County, including Aurora, northern Will County, portions of Cook County, and parts of Kendall County, such as Yorkville. This region of Chicagoland represents one of the largest local calling areas in the United States.

Nearby area codes include:

  • 224 (Elgin, IL)
  • 312 (Chicago, IL)
  • 773 (Chicago, IL)
  • 815 (Rockford, IL)
  • 847 (Elgin, IL)

The 630 area code was created on August 3, 1996, as a split from the 708 area code to address the growing demand for telephone numbers in Chicago’s western suburbs. The introduction of 630 reflected the significant growth and suburban expansion of the greater Chicago metropolitan area in the late 20th century, as more people and businesses moved to these communities.

Key Economic Zones & Business Hubs

  • Major Cities: Aurora, Naperville, Wheaton, Downers Grove, Elmhurst, Oak Brook, Lombard, Glen Ellyn
  • Economic Zones: DuPage County corporate corridor, Kane County tech hub, Will County industrial areas
  • Business Hubs: Oak Brook corporate headquarters district, Naperville technology corridor
  • Neighboring Area Codes: 331 (overlay), 312/773/872 (Chicago), 847/224 (northern suburbs), 708 (southern suburbs)
  • Strategic Position: Central location between Chicago proper and western suburban markets

Time Zone & Business Impact

The 630 area code operates on Central Time Zone (CT), following Central Standard Time (CST) at UTC-6:00 during standard time and Central Daylight Time (CDT) at UTC-5:00 during daylight saving time. This time zone positioning offers businesses a strategic advantage; you'll be synchronized with Midwest corporate schedules and can easily coordinate with national headquarters.

The Central Time Zone creates a practical window for communication. You can reach East Coast clients during their morning hours and connect with West Coast partners in the afternoon. Business calls typically see the best response rates between 9 AM and 5 PM CT, when Chicago-area residents and professionals are most available.

  • East Coast Coordination: Morning overlap allows early client communication and collaboration
