Area Code Breakdown & Regional Mapping
617 – Boston’s Core Code
Area code 617 is Boston’s original 1947 code, and it covers Quincy as part of the inner Greater Boston core just across the Neponset River from the city. A 617 number ties Quincy into the region’s central dialing area.
857 – Greater Boston Overlay
Area code 857 is the 2001 overlay for the 617 region, sharing the same Greater Boston geography that includes Quincy. Many newer Quincy lines carry an 857 prefix, fully local to existing 617 numbers.
Neighborhoods & Local Coverage
Quincy’s 617/857 codes cover a historic coastal city anchored by Quincy Center, home to the Adams National Historical Park and the presidents’ birthplaces. The waterfront Marina Bay district and the Squantum peninsula offer harbor views, while Wollaston Beach lines the shore along Quincy Bay.
Beyond the center, the same codes reach the North Quincy neighborhood — home to a large and growing Asian-American community — along with the Adams Shore, Houghs Neck, and Merrymount areas. As part of Greater Boston, Quincy shares the 617/857 codes with the city just to the north.
Local Dialing Rules & International Format
Quincy and all of eastern Massachusetts have required 10-digit dialing for years — always dial the area code plus the 7-digit number. The Greater Boston core uses 617, overlaid by 857. The South Shore suburbs beyond Quincy use 781/339.
To call Quincy from outside the United States, dial your country’s exit code, then the U.S. country code +1, followed by the 10-digit number (for example, +1 617 XXX-XXXX). From inside the U.S. and Canada, simply dial 1 before the 10-digit number for long-distance calls.
Major ZIP Codes Covered
The 617 service area spans many of Quincy’s core ZIP codes, including 02169, 02170, and 02171.
Spam & Scam Call Warnings in Quincy
Quincy residents report neighbor-spoofing robocalls faking a local 617 prefix, plus fake utility-shutoff threats from callers posing as National Grid. Bilingual robocalls also target the city’s large Asian-American community.
| Scam Type | What to Watch For |
|---|---|
| Neighbor Spoofing | Calls that mimic a local 617 prefix to look familiar. |
| Utility / Toll Scams | Threats to shut off power or demand toll payment via gift cards. |
| IRS / Government | Robocalls claiming legal action — agencies never call to demand instant payment. |
Red flag: Any caller who pressures you to pay immediately with gift cards, wire transfers, or cryptocurrency is almost certainly running a scam. Hang up and verify through an official number.
