Hyannis is the commercial village of the Town of Barnstable. Hyannis Harbor is the Steamship Authority's mainland port for Nantucket, and Cape Cod Hospital sits in the village.
A company is numbered when its own site, or an existing Solvo record, confirms commercial pest control and the Cape Cod file already holds a Solvo Score. Town pages also require the town by name. Confidence tier leads the sort.

These records sit in the Cape Cod file. The service line or the town rule keeps them off the numbered list.
The office is 100 Independence Drive, Suite 7-926, Hyannis. The site says all of Cape Cod, Plymouth, and Wareham. That phrase does not name Hyannis, so the office does not earn a number on this page.
Same rubric as every scored page on Solvo Index: six weighted categories, scored 0 to 10 against fixed anchors, combined into a Solvo Score from 0 to 100 and capped at 97.0. Evidence completeness sets the confidence tier: HIGH at 90% and above, MEDIUM from 70 to 89%, LOW below 70%. A connected operating system carries a Verified tier above HIGH. Every ranked company carries at least one published weakness. Payment does not buy a score or a position. Full methodology: Solvo Score Methodology.
