Area Code 351 — Fast Facts

About Area Code 351

If you've received a call from a number starting with 351, you're hearing from someone in or around Lowell, MA. This doesn't guarantee the caller is physically located there — phone number spoofing allows any caller to display a local area code. A reverse phone lookup can tell you the actual registered carrier and owner behind the number, regardless of what your caller ID shows.

The 351 area code has been active since 2001 and is managed by NANPA (North American Numbering Plan Administration) under the North American Numbering Plan. Numbers in this area code follow the standard NANP format: (351) XXX-XXXX.

How to Look Up a 351 Phone Number

Looking up a 351 number on RevealNames is straightforward. Enter the full 10-digit number (including the 351 area code) into the search box at the top of this page. Our system cross-references carrier CNAM databases, public records, and spam report databases to return:

• The registered owner's full name — first and last name as registered with the carrier
• City and state location — where the number is registered, which may differ from the caller's physical location
• Carrier name — AT&T, Verizon, T-Mobile, or any of the regional or MVNO carriers serving the Lowell area
• Line type — whether the number is a mobile cell phone, landline, VOIP line, or toll-free number
• Spam reports — community-sourced flags if the number has been reported for robocalling, telemarketing, or fraud

Results are returned anonymously — the person you're looking up never finds out you searched their number.

Phone Scams Targeting 351 Numbers

Like every active area code, 351 numbers are regularly spoofed by scam operations. When a call comes from what looks like a local Lowell, MA number but turns out to be a robocall or fraud attempt, the scammer is using neighbor spoofing — a technique that replaces the real originating number with a local-looking one to boost answer rates.

Common scams hitting 351 numbers include IRS impersonation calls, fake Social Security Administration notices, auto warranty robocalls, Medicare fraud attempts, and "local business survey" calls that are actually lead harvesting operations. The 351 area code is particularly targeted because of the population density and income demographics of the Lowell area.

Before you call back a 351 number you don't recognize, run a free reverse phone lookup above. A genuine call from a business or individual will have a registered name and carrier. A spoofed scam number often shows as unregistered, assigned to a VOIP carrier, or has multiple spam reports attached to it.

If you identify a scam number, report it to the FTC at reportfraud.ftc.gov and the FCC at consumercomplaints.fcc.gov. Your reports help build enforcement cases.
