Area Code Overview
Area code 630 was established in 1996 as a split from the 708 code, created specifically to serve DuPage County and adjacent western Cook County communities as suburban growth demanded more numbers. The code covers Naperville, Aurora, Downers Grove, Wheaton, Elmhurst, Oakbrook Terrace, and Lisle — a corridor that constitutes one of the most economically productive suburban counties in the Midwest.
DuPage County consistently ranks among the wealthiest counties in Illinois and in the top tier nationally by median household income. The western suburbs serve as home to regional and national corporate headquarters, including major presences in Downers Grove, Oak Brook, and Naperville. The county has historically attracted corporate relocations from downtown Chicago seeking lower costs, and it houses a substantial senior population in established communities like Wheaton and Glen Ellyn. This combination — corporate density, high homeowner wealth, and a large population of retirees on fixed incomes — makes 630 territory a structured fraud target with several region-specific patterns.
Scam Patterns in 630
ComEd Utility Disconnection Fraud
Commonwealth Edison (ComEd), the Exelon subsidiary that is the sole electric utility for northern Illinois including all of DuPage County, is among the most impersonated companies in 630 scam campaigns. Texts sent to 630 residents claim the recipient's account is severely past due and that power will be disconnected within hours unless immediate payment is made through a provided link or a prepaid debit card purchased at a nearby retailer. The fraud is calibrated to provoke urgency — often referencing extreme weather days when losing power would be especially dangerous. ComEd does not demand same-day payment via text link and explicitly warns customers about this impersonation pattern on its website. Disconnection in Illinois requires formal advance notice under Illinois Commerce Commission rules and cannot occur the same day a text is received. If you receive such a text, log into your ComEd account directly at comed.com or call the number on your paper bill.
DuPage County Property Tax Exemption Fraud
DuPage County homeowners — particularly seniors, veterans, and long-term residents — are eligible for various property tax exemptions under Illinois law, including the Senior Citizens Homestead Exemption, the Senior Citizens Assessment Freeze Exemption, and the General Homestead Exemption. Scam texts targeting 630 numbers offer to file or renew these exemptions on the recipient's behalf for a "filing fee" or "processing deposit," sometimes impersonating the DuPage County Supervisor of Assessments office. The fraud is effective because these exemptions are real, the filing process does require periodic renewal, and many senior homeowners are uncertain whether their exemptions are current. The DuPage County Supervisor of Assessments provides exemption filing assistance for free; any text requesting payment to secure or renew a property tax exemption is fraudulent. Homeowners can verify exemption status at dupageco.org.
Fortune 500 Corporate Relocation and Signing Bonus Phishing
DuPage County and the western suburbs host or have recently hosted the headquarters or major campuses of a number of large corporations — including companies in Downers Grove, Oakbrook Terrace, and Naperville. The high concentration of corporate professionals in the area makes 630-targeted phishing that exploits employment themes particularly effective. Scam texts impersonate HR departments of real western suburban employers, offering relocation packages, signing bonuses for accepting a position, or remote onboarding kit deposits — all requiring the target to provide direct deposit information or pay a small "processing fee" upfront. These messages frequently exploit news of actual corporate moves or expansions in the area to add verisimilitude. Any job offer or benefit communication that arrives via unsolicited text should be verified through the company's official HR contact found independently.
VoIP and Spoofing Risk Assessment
Risk Level: MOD
630 has a relatively balanced number mix: the corporate concentration brings legitimate business VoIP and enterprise wireless, while established residential communities retain a higher landline proportion than younger suburban codes. The moderate risk level reflects the fact that 630 is a prime spoofing target given the high wealth of its residents and the credibility that a DuPage County number lends to corporate impersonation. Scam operations targeting corporate professionals — signing bonus phishing, relocation fraud — are specifically calibrated to the western suburbs' economic profile.
What To Do If You Receive a Text From a 630 Number
- Do not click any link in a text claiming to be from ComEd, a DuPage County government office, or an employer's HR department. Navigate directly to official websites by typing the address in your browser.
- Look up the number at Who Sent That Text Message to check for prior reports and to identify whether the number is a VoIP line before responding.
- Verify your ComEd account status at comed.com and verify property tax exemption status at dupageco.org using contact information you find yourself — not from the text. See our guide on identifying spoofed text messages.
- Report the text by forwarding to 7726 (SPAM). File with the FTC at reportfraud.ftc.gov. Utility impersonation in Illinois can also be reported to the Illinois Commerce Commission at icc.illinois.gov.
Frequently Asked Questions

Area code 630 covers DuPage County and adjacent western suburban communities in northeastern Illinois, including Naperville, Aurora, Downers Grove, Wheaton, Elmhurst, and Lisle. It was created in 1996 as a split from the 708 area code to accommodate suburban growth.
Is area code 630 a scam?
630 is a legitimate area code used by DuPage County residents and businesses. It is, however, spoofed in targeted fraud campaigns — particularly ComEd utility disconnection texts and employment-related phishing — because the western suburbs' affluent demographic profile makes it an attractive target. An unknown 630 text requesting payment or personal information should be verified before any action is taken.
Does ComEd send disconnection notices by text?
ComEd may send account-related text notifications to customers who have enrolled in text alerts through their official account portal. ComEd does not send unsolicited texts to unenrolled customers demanding immediate payment via a link or prepaid card to avoid disconnection. Any such text is fraudulent. Check your account status directly at comed.com or call ComEd's customer service line.
