The 401 area code is the single area code serving the entire state of Rhode Island, the smallest state in the country. Assigned in 1947 as one of the original area codes, 401 has covered all of Rhode Island on its own ever since and has become a beloved symbol of Ocean State pride.
Quick Summary of the 401 Area Code

| State | Rhode Island (RI) |
| Region | Statewide Rhode Island |
| Major Cities | Providence, Warwick, Cranston, Pawtucket, East Providence, Woonsocket, Newport, Coventry |
| Time Zone | Eastern Time (ET) – EST / EDT |

Geographic Coverage
The 401 area code is a statewide code covering all of Rhode Island, including the capital and largest city of Providence, the neighboring cities of Cranston, Pawtucket, East Providence, and Woonsocket, the airport city of Warwick, the seaside resort of Newport at the mouth of Narragansett Bay, and Coventry to the west. Despite covering the entire state, Rhode Island is so compact that the whole 401 region spans barely 50 miles end to end. It borders Massachusetts and Connecticut and opens onto the Atlantic Ocean.
Time Zone
The 401 area code observes Eastern Time (ET). Clocks follow Eastern Standard Time (UTC−5) in winter and shift to Eastern Daylight Time (UTC−4) from mid-March through early November. All of Rhode Island is on Eastern Time, the same as neighboring Massachusetts and Connecticut. From the West Coast, this region is three hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 401 number at 12:00 PM local time.
Tip: Business hours across the 401 region generally run 9:00 AM to 5:00 PM Eastern Time, Monday through Friday.
How to Dial a 401 Number
Area code 401 is not part of an overlay, and as the only area code in Rhode Island it has traditionally allowed 7-digit local dialing within the state. However, 10-digit dialing is now the recommended nationwide standard, and dialing the full 10-digit number (401 + the seven-digit line number) always works reliably. For international callers, dial your country’s exit code, then +1 (the North American country code), then 401, followed by the seven-digit local number.
Scam Alerts for the 401 Area Code
Like every U.S. area code, 401 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Providence, Warwick, Cranston, Pawtucket, East Providence, Woonsocket, Newport, Coventry should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Callers claiming you owe back taxes and threatening arrest unless you pay immediately. |
| Utility Shut-off | Fake Rhode Island Energy reps demanding payment to avoid disconnection. |
| Bank Fraud Alerts | Robocalls impersonating your bank about “suspicious activity” to phish account details. |
| Grandparent Scam | A caller posing as a relative in trouble asking for emergency wire transfers. |
If you receive a suspicious call from a 401 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the Rhode Island Attorney General’s Consumer Protection Unit.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (Rhode Island Energy) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 401 caller making such a demand is a scammer.
History and Economy of the 401 Region
n
Area code 401 is one of the original 86 codes established in 1947, and because Rhode Island is the smallest state by area, a single code has always been more than enough – 401 has never needed an overlay or a split. The “401” has become a strong emblem of Rhode Island identity, appearing on apparel, businesses, and local slogans. Providence anchors the regional economy as the capital and home to Brown University and the Rhode Island School of Design (RISD), along with a healthcare, financial-services, and education sector and a historic jewelry-and-manufacturing heritage. Woonsocket is the headquarters of CVS Health, one of the largest companies in the country, Pawtucket is home to the toy giant Hasbro, and Newport draws visitors worldwide to its Gilded Age mansions, sailing regattas, and Naval Station Newport. Tourism thrives across Narragansett Bay, the state’s beaches, and Block Island.

To identify a 401 caller, use a reverse phone lookup service or search the full 10-digit number online. Many Rhode Island businesses, government offices, and healthcare providers list their 401 numbers publicly, so a quick search often confirms a legitimate caller. For unknown numbers, let the call go to voicemail – genuine callers usually leave a message, while robocallers and scammers rarely do.
