The established/overlay split is dramatic. Hartford (860) and New Haven (203) have 67-75% in-state targeting with medical and impersonation as top categories. Their overlay counterparts (475 at 38.5% and 959 at 47.4%) are heavily used for out-of-state automated debt campaigns.
Hartford vs. New Haven: Two Scam Ecosystems
Connecticut's two metro areas have distinct profiles.
| Area Code | Coverage | Complaints | In-State % | #1 Category |
|---|---|---|---|---|
| 860 | Hartford / Eastern CT | 41,757 | 74.5% | Medical (2,735) |
| 959 | Hartford (overlay) | 11,057 | 47.4% | Debt (1,534, 88.9% robocall) |
| Hartford Metro | 52,814 | |||
| 203 | New Haven / Bridgeport | 32,918 | 67.7% | Impersonation (3,073) |
| 475 | New Haven (overlay) | 28,452 | 38.5% | Debt (4,833, 86.1% robocall) |
| New Haven Metro | 61,370 |
New Haven's 475 overlay has the most debt complaints of any Connecticut area code at 4,833 with an 86.1% robocall rate. Its 38.5% in-state targeting confirms it functions as a nationwide automated campaign launchpad, similar to 518 Albany (36%) and 502 Louisville (46.7%).
Energy and Utility Scams: Connecticut's Distinctive Threat
Energy, solar, and utility scams rank #4 statewide at 5,074 complaints (53.8% robocall rate). This represents 4.4% of all Connecticut complaints, the highest utility scam share of any state in our series.
| Area Code | Energy/Utility Complaints | Robocall % |
|---|---|---|
| 860 Hartford | 2,361 | 59.1% |
| 203 New Haven | 1,608 | 50.3% |
| 475 Overlay | 469 | 40.9% |
| 959 Overlay | 271 | 29.2% |
| State Total | 5,074 | 53.8% |
Eversource (the state's largest electric utility) and United Illuminating are the primary targets of impersonation. Connecticut's high electricity costs (among the highest in the nation) make customers receptive to calls promising rate reductions or threatening disconnection. The pattern mirrors the utility scam crises documented in Massachusetts (5,958 energy complaints), New Jersey (13,646), and Pennsylvania (14,513).
Connecticut's Scam Category Profile
| Rank | Scam Category | Complaints | Robocall % |

| 6 | Charities | 1,575 | 58.2% |
| 7 | Home improvement and cleaning | 1,192 | 38.9% |
| 8 | Vacation and timeshares | 562 | 39.0% |
Debt reduction leads at 9,534 with an 81.2% robocall rate. The top three categories are tightly clustered (9,534 / 9,337 / 6,912). Charities rank #6 with 1,575 complaints, elevated by the 475 overlay (521) and 959 overlay (319), suggesting charity scam campaigns being launched through Connecticut overlay codes.

Neighbor Spoofing: The Established/Overlay Divide
| Highest In-State | % | Lowest In-State | % |
|---|---|---|---|
| 860 Hartford | 74.5% | 475 New Haven overlay | 38.5% |
| 203 New Haven | 67.7% | 959 Hartford overlay | 47.4% |
Connecticut's statewide average of 57.0% in-state targeting is below the national norm. The 36-point gap between Hartford (74.5%) and the New Haven overlay (38.5%) is among the widest established/overlay splits in our series. This pattern is consistent across all states: overlay codes carry more out-of-state automated campaign traffic because they are newer, less associated with a specific city, and have deeper VoIP number pools.
