What it shows

  • 254: territory and service records
  • 12: codes shared by territories
  • 51: territories in shared-code groups

Keep the territory and calling code as separate fields. A calling-code-only join merges distinct territories in every orange group.

Method

Group territorial records by calling_code. Non-geographic service records with territory 001 are excluded from sharing counts and map. Source territory distinctions are preserved.
