Use Dennis geography to define the intake boundary
Dennis is the relevant municipal geography, and Barnstable County is the recorded county relationship. A page or intake flow should not treat the town, the county, Massachusetts and a broader metropolitan area as interchangeable. Ask which inquiries your firm accepts from Dennis, whether county-wide matters belong in the same path and when a location answer should trigger human review.
Recommended approach
Start with an explicit service-area decision. Keep Dennis as a selectable location where it is relevant, then document what the team should do with an inquiry from elsewhere in Barnstable County or from another Massachusetts location.
