Advertising Plumbing Services

For the protection of its citizens, the State of Illinois requires that any person advertising plumbing services must include the Plumbing License Number of one member of the firm, partnership or officer of the corporation in all advertisements. The law further requires that this number be included with the plumbing identification on all vehicles.

The lack of such a number on a plumbing vehicle or in an advertisement for plumbing services is a violation of state law. Proceed carefully before hiring a firm who violates a state law that has been in existence for many years.

At the place of business, the law further requires that this license is displayed and that a register listing the names and license number of all licensed plumbers and all licensed apprentice plumbers currently employed by the firm must be maintained.
