What licence age does and does not mean

A registration first issued decades ago means the credential has been maintained that long. It does not necessarily mean the same people run the business, or that the business has traded continuously — ownership can change while a registration is kept alive. Read it as a fact about the licence, not a citation for the firm. Method is on the sources page.

For contractors

Been licensed for decades and still invisible online?

A registration from 1987 is worth more than any badge a directory can sell you. Most homeowners will never see it unless your website says so.
