Close enough to St. Louis to matter
Waterloo sits near the St. Louis, Missouri metro, so a 618 number still reads as regional to people across the river, not like a call from out of state.
Belleville shares your area code
Area code 618 is common in Belleville too, the larger city just up the road from Waterloo. A Waterloo number looks familiar to neighbors there.
O'Fallon and Collinsville see a familiar number
Friends and clients in nearby O'Fallon and Collinsville, both Illinois towns close to Waterloo, will recognize a 618 number as one of their own.
