WALTHAM, MA – National Grid is alerting customers to be aware of scam calls targeting residents and businesses across its service territory. If contacted by someone claiming to represent the company, National Grid recommends that customers always ask for identification.

These scams typically involve callers claiming a customer's account is past due and threatening immediate service disconnection unless payment is made. Scammers may also use “spoof” phone numbers, so calls appear from National Grid.

National Grid reminds customers that while the company may contact customers regarding their accounts or service, it will never demand immediate payment through prepaid cards, gift cards, wire transfers, cryptocurrency, or third-party payment apps.

Customers should be aware of common red flags, including:

• Threats of immediate service disconnection without prior written notice
• Requests for personal, financial, or account information
• Demands for immediate payment using prepaid or non-traditional payment methods
• Callers who cannot verify account details

 National Grid encourages customers to verify any suspicious communication by contacting the company directly using the phone number listed on their bill. Customers should never provide personal or financial information to an unsolicited caller.

If you suspect a scam, hang up immediately and report the incident to National Grid or local law enforcement.
