508 Area Code: A Guide to Worcester and Southeastern Massachusetts

Quick answer: Area code 508 is the telephone prefix for central and southeastern Massachusetts, covering Worcester, New Bedford, Brockton, Plymouth, and the entire Cape Cod peninsula including Martha's Vineyard and Nantucket. It sits in the Eastern Time Zone and has shared its territory with the 774 overlay since May 2001, making ten-digit dialing mandatory for every call in the region.

What is the 508 area code?

The 508 area code is the telephone prefix for a large and geographically diverse stretch of Massachusetts, anchored in the west by Worcester — the state's second-largest city — and reaching east across the South Coast, Plymouth, and all the way to the tip of Cape Cod and its offshore islands.

It is one of the most recognizable codes in New England, associated with a region that mixes urban medical and academic institutions with historic fishing ports and a world-famous resort coastline.

Like the 484 area code, which shares its eastern Pennsylvania geography with the 610 and 835 codes, 508 now operates alongside a second prefix. In May 2001, area code 774 was introduced as an all-services overlay for the same territory, meaning newly issued lines across the region may carry either 508 or 774 while every existing 508 number stays exactly the same.

For residents and businesses, the overlay means one practical change: every call within the 508/774 region requires all ten digits, including calls to a neighbor on the same block. The 508 prefix itself continues to signal genuine Massachusetts roots.

Cities and counties in the 508 area code

The 508 area code spans one of the most varied regional footprints in the Northeast. It stretches from the inland city of Worcester across the densely populated South Coast, down through the cranberry bogs of Plymouth County, and out along the narrowing arm of Cape Cod to the ferry terminals for Martha's Vineyard and Nantucket.

Major cities and communities in the 508 area:

• Worcester — Massachusetts's second-largest city, a healthcare, biotech, and higher-education hub at the geographic center of the state
• New Bedford — Historic whaling port now home to one of the most valuable commercial fishing fleets in the United States
• Brockton — A mid-size city in Plymouth County with a strong manufacturing and healthcare base
• Fall River — A former textile-manufacturing center on Narragansett Bay, now a regional commercial hub
• Taunton and Attleboro — Bristol County cities along the I-95 and Route 44 corridors
• Plymouth — America's oldest continuously inhabited English colonial settlement, a growing coastal community south of Boston
• Framingham — A Middlesex County city on the Mass Pike corridor, home to corporate headquarters and a major medical center
• Barnstable, Falmouth, and Hyannis — The commercial center and major communities of Cape Cod
• Martha's Vineyard and Nantucket — Island communities reached by ferry from the South Coast, served by 508 numbers throughout

Counties within the 508/774 service territory:

The entire 508 coverage area observes Eastern Time (UTC−5 in winter, UTC−4 during DST). Because 508 shares its time zone with Boston and New York, coordinating calls across the region and into the rest of the Northeast is straightforward, though callers from Chicago or other Central Time cities should remember that southeastern Massachusetts runs one hour ahead.

A short history of the 508 area code

Massachusetts began the telephone era under area code 617, which covered the entire state from its creation in 1947. As the postwar decades brought population growth, more telephone lines, and eventually the first wave of mobile devices, 617's supply of available numbers began to run thin.

On July 16, 1988, area code 508 was split from 617 to serve the areas outside Boston's immediate ring — including Worcester, the South Coast, Cape Cod, and the western suburbs. Boston and the inner suburbs retained 617, while the rest of the state transitioned to 508 with a permissive dialing period running through early 1989.

Nine years later, growth in the northern part of the 508 region drove a second split. On September 1, 1997, area code 978 was carved out of 508 to serve the communities north and west of Boston, including Lowell, Lawrence, and Gloucester, leaving 508 to cover the central and southern portions of the state.

Even after losing its northern territory, 508 continued to exhaust its number supply faster than expected. The Massachusetts Department of Telecommunications and Cable worked with the North American Numbering Plan Administration to add area code 774 as an all-services overlay, effective May 2, 2001, with mandatory ten-digit dialing required from that date forward.

Key milestones:

• 1947 — Area code 617 assigned to all of Massachusetts
• 1988 (Jul 16) — 508 split from 617 to serve central and southeastern Massachusetts
• 1997 (Sep 1) — 978 split from 508 to serve northern Massachusetts
• 2001 (May 2) — 774 added as an all-services overlay; ten-digit dialing becomes mandatory

Calling a 508 number

Because 508 and 774 share the same territory, ten-digit dialing is mandatory for every call in the region — including calls between neighbors in the same neighborhood. Ten-digit dialing has been required since May 2001, so any contact stored without the area code should be updated to the full ten-digit format.

Time zone tip: Southeastern Massachusetts observes Eastern Time — the same zone as Boston, New York, and Philadelphia. It runs one hour ahead of Central Time cities like Chicago, two hours ahead of Mountain Time, and three hours ahead of Pacific Time. When scheduling calls with partners on the West Coast, keep that three-hour gap in mind.

Why a 508 number is good for business

The 508 region combines one of New England's largest inland cities with a nationally significant fishing port, a globally recognized resort coastline, and a dense concentration of universities and medical institutions — a diversity that makes a local 508 number an asset across a wide range of industries.

Reasons to choose a 508 area code number:

• Healthcare and biotechnology — Worcester hosts UMass Memorial Medical Center, UMass Chan Medical School, and Saint Vincent Hospital, making it a major hub for medical services, life-sciences research, and pharmaceutical supply chains
• Higher education — Worcester Polytechnic Institute, College of the Holy Cross, Clark University, and Framingham State are among the institutions that bring tens of thousands of students, researchers, and faculty into the 508 economy
• Commercial fishing and maritime — New Bedford consistently ranks among the most valuable commercial fishing ports in the entire United States, supporting vessel services, processing plants, cold-chain logistics, and marine supply businesses
• Tourism and hospitality — Cape Cod, Martha's Vineyard, and Nantucket together draw millions of visitors each summer, sustaining a vast seasonal economy in accommodations, dining, boat tours, and retail
• Virtual reach — Just as businesses connect with New Orleans customers through a 504 area code number without a physical office there, a virtual 508 number routes calls to any device and establishes a genuine southeastern Massachusetts presence from any location

508 area code scam calls to watch for

Because 508 is instantly recognized as a Massachusetts number across a densely populated region, scammers spoof it to appear local and familiar. Neighbor spoofing — displaying a 508 prefix that matches a caller's own exchange — is particularly effective in communities where residents regularly receive calls from healthcare providers, universities, and utility companies.

Common 508 scam types to watch for:

• Medicare and Medicaid fraud — Scammers impersonating health insurance coordinators or government benefit agents to capture Medicare numbers, the most frequently reported scam type in the 508 region
• Medical device scams — Callers claiming to offer free medical equipment, back braces, or pain-relief devices in exchange for Medicare or insurance information
• Utility shutoff threats — Fraudsters posing as National Grid representatives demanding immediate payment to prevent electricity or gas disconnection, a common tactic across all seasons
• Social Security suspension fraud — Automated calls claiming a Social Security number has been suspended due to fraudulent activity, frequently targeting seniors across Worcester and the South Coast
• Fake legal and debt-collection threats — Callers threatening lawsuits, arrest, or wage garnishment to extract payment or personal information from residents and small-business owners

How to protect yourself:

• Let unknown 508 calls go to voicemail and verify the caller independently before responding
• No government agency, hospital, or utility will ever demand payment by gift card, wire transfer, or cryptocurrency during an unsolicited call
• Confirm any organization through the contact details on its official website
• Report suspected 508 scam calls to the FTC at reportfraud.ftc.gov
