sort of, At home, no one uses street numbers, it is usually directions.
Color of houses, landmarks, etc.
Example, our address was #3 Taanaberg, however directions,was two story house on the top of Pollyberg Hill, across from Glass Bottle Alley.
As the plantations were broken up and developed, street names and numbers were issued by Public Works.
Here's a suggestion, King Street is a 'main' Street, and the business'address will not change, just the name of the business, try gaugeing,using that method.
BTW, I know St. Thomas better, and thinking about it, there are no addressed for some business' in the phone book, just Main Street!
I'll keep checking
