About the 351 region
351 covers Lowell in Massachusetts, including Acton, Ashburnham, Ashby, Andover and Amesbury. The code has been in service since 2001.
351 itself is an overlay: it shares its territory with 978 and was introduced when those codes ran low on new number combinations. New lines may receive either code, calls between them are local, and 10-digit dialing is required across the region.

Who called me from 351?

- Avoid calling back unknown one-ring numbers — some premium-rate scams rely on curiosity callbacks.
- Never share verification codes, payment details, or remote access during an unsolicited call, even if the caller claims to be your bank or a government agency.
- When a 351 call pressures you to act immediately, hang up and contact the organization directly through its official number.
