Is area code 618 a scam?
No. Area code 618 is a legitimate area code serving Belleville since 1947. Scammers spoof caller ID to display 618 numbers, which is why complaints exist against a code that is itself genuine.
Neighbour spoofing is the reason a local-looking number is not a guarantee. A caller anywhere in the world can display a 618 number, and the number they display may belong to a real business in Belleville that has nothing to do with the call.

Who works in the Belleville area?
Belleville is the largest city in the Metro East, the Illinois side of Greater St. Louis, and the seat of St. Clair County. The economy that once ran on coal mines and stove factories, when the city called itself the Stove Capital of the World, now runs on Scott Air Force Base, home of U.S. Transportation Command and the region's dominant employer. The base gives Belleville an outsized population of military personnel, federal civilians, and defense contractors, and their paychecks steady the local service economy. Healthcare fills much of the rest, with the HSHS and Memorial hospital systems among the larger private employers. Median household income was $63,535 in 2024, with a median property value of $141,300 that keeps the cost of living well below the St. Louis side of the river (Census ACS via DataUSA).
Who lives in the 618 region
The 2020 census counted 42,404 residents, and the population held near 41,400 in 2024. The city is about 57% White and 33% Black, with a Hispanic population under 3% and only 2.9% of residents born outside the United States (DataUSA, 2024). English is effectively the only language of business here, and the German heritage that shaped the town in the 1800s survives in street names and festivals rather than speech.
What a 618 number signals to a caller
Area code 618 has covered southern Illinois since 1947, one of the state's original codes, stretching from the Metro East down to Cairo. A 618 number reads as downstate, distinct from Chicago's 312 in every way that matters to an Illinois ear. Callers describe the business style as small-town Midwestern: direct, thrifty, and built on repeat relationships. It is generally expected that you know whether you are calling before or after a shift change at the base, and Belleville, Illinois runs on Central time with St. Louis rather than on any Chicago schedule.
