Area Code Overview
Area code 847 was created in 1996 as a split from 708, taking over the northern suburban Chicago territory. It covers a broad arc of Lake and Cook County communities north and northwest of the city: Evanston, Skokie, Glenview, Niles, Des Plaines, Rosemont, Schaumburg, Palatine, Arlington Heights, Waukegan, Gurnee, and Highland Park, among others. This is some of the most economically diverse suburban territory in the Midwest — the North Shore corridor running along Lake Michigan (Evanston, Wilmette, Winnetka, Glencoe, Highland Park) contains some of the highest household incomes and real estate values in Illinois, while Waukegan and North Chicago anchor working-class Lake County to the north.
Northwestern University (Evanston campus) and Northwestern Medicine are the dominant institutional presences. O'Hare International Airport's northwest perimeter grazes the 847 footprint through Rosemont and Des Plaines, and the Schaumburg commercial corridor is one of the largest retail and office concentrations in Illinois outside downtown Chicago.
Scam Patterns in 847
O'Hare Airport Flight Disruption and Airline Refund Fraud
O'Hare International is one of the busiest airports in the world and is notorious for weather-related and operational delays, particularly during winter. Scam texts from 847 numbers exploit this by impersonating airlines — most commonly American Airlines and United Airlines, both of which have major O'Hare hubs — claiming a flight has been cancelled or significantly delayed and offering a refund or rebooking credit that must be claimed through a link in the message. A variant impersonates O'Hare's parking payment system, claiming an outstanding parking fee will result in a vehicle hold or collection action. Because O'Hare disruptions are genuinely common and airline rebooking processes are legitimately confusing, these texts are effective — travelers are primed to act quickly when they think their travel plans are at risk. Neither American nor United will send unsolicited rebooking or refund links. Manage all flight changes through the airline's official app or website using your booking confirmation.
North Shore Property Tax Exemption and Senior Freeze Fraud
Lake County and the North Shore communities of Cook County have some of the highest residential property tax bills in the state of Illinois — and Illinois has among the highest property tax rates in the nation. Property tax exemptions, including the Senior Citizen Homestead Exemption and the Senior Citizen Assessment Freeze (Senior Freeze), represent real and significant dollar savings for qualifying homeowners. Scammers send texts from 847 numbers targeting homeowners — particularly older residents in Highland Park, Wilmette, Northbrook, Deerfield, and Glenview — offering to file for exemptions for an upfront fee. A second variant impersonates Cook County or Lake County assessor's offices, claiming a property assessment error will result in a retroactive tax bill unless the homeowner verifies their information at a link in the message. Both county assessors communicate by mail and have official portals; they do not collect personal information or payments via text message links.
Northwestern Medicine and NorthShore University HealthSystem Medical Billing Fraud
Northwestern Medicine and NorthShore University HealthSystem (now part of Endeavor Health) are the two dominant healthcare networks across Chicago's north suburbs, serving hundreds of thousands of patients across the region. Medical billing fraud exploiting these brands is among the most complained-about scam categories in this area code. Texts from 847 numbers impersonate patient billing departments, claiming an outstanding balance will be sent to collections or that a payment method has failed, with a link to resolve the issue. A parallel variant claims the recipient is eligible for a medical bill reduction or financial hardship waiver and must submit financial information to qualify. Northwestern Medicine and Endeavor Health/NorthShore bill through their official patient portals (MyChart) and paper mail. Unsolicited texts with payment links claiming to be from either health system should be treated as fraudulent.
VoIP and Spoofing Risk Assessment
Risk Level: MOD
847 covers a wide geographic footprint with a mature number pool drawn from decades of suburban growth. VoIP usage is heavy across the commercial corridors of Schaumburg, Arlington Heights, and Rosemont — the airport adjacency means a large hospitality, logistics, and business travel industry with significant VoIP telephony. The North Shore's high household incomes make it a target for property tax and financial fraud specifically calibrated to high-net-worth suburban demographics. Healthcare billing fraud exploiting Northwestern Medicine and NorthShore's dominant market position is particularly persistent given the volume of patients these systems serve.
What To Do If You Receive a Text From a 847 Number

Handle airline disruptions through official apps only. If you receive a flight cancellation or refund text, open your airline's official app or go directly to aa.com or united.com and log in with your booking reference. Never click a rebooking link in an unsolicited text.
