The 301 area code is frequently used for grandparent bail scams and unsolicited texts about buying your home. Scammers often use emotional manipulation or constant messaging to trick you into sending money or giving up personal details.
"Caller pretended to be grandson and needed bail money because he was in jail for drunk driving, getting in an accident, etc. Really upset my elderly parents. Special place in hell for you scammer who prays on the elderly."
"Hey [NAME], my apologies for the surprise msg. I hope you are staying healthy! I'm Nate, a local realtor and I am interested in buying the property at [ADDRESS]. Do I have the right person?"
"Robocall says this is Officer xxxxx, a complaint has been filed against your social security number and 'this is the last attempt to contact you'."
"They left a voicemail saying that I needed to call them back about a claim against me. Pretty sure it's bogus."
"Received a message... stated that they are the IRS saying that I need to call them about a very important legal matter saying I am in jeopardy of legal conflict and said myself or my attorney needed to call them back immediately or face imprisonment...."
"Call with an automated message, pretending to be Amazon customer service. They tell you that there was a fraudulent charge on your account, then they tell you to press 1 to talk to customer service."
"I have asked this company repeatedly for more than 4 years to stop calling me. It is a car warranty extension. I receive an average of 8-10 calls per week from this and other numbers associated with them. NO doesn't work with them. I'm at the end of my rope with them."
Area code 301 covers the western part of Maryland, encompassing areas within the Greater Washington, D.C. metropolitan region, sections of southern Maryland, and rural western Maryland.
Area code 301 is part of an overlay system with area codes 240 and 227 . This means that multiple area codes serve the same geographic region. Area code 301 was established in 1947, area code 240 was added in 1997, and area code 227 was added on June 14, 2023. Ten-digit dialing is required for all calls within this region.
No, area code 301 is a legitimate phone prefix covering the Maryland suburbs of Washington D.C., including Silver Spring and Waldorf. Fraudsters spoof it to make their calls look familiar, trustworthy, and government-adjacent.
Social Security Administration impersonators who threaten to suspend your SSN and IRS arrest-warrant robocalls from fake Treasury special agents dominate the complaints here. Grandparent bail-money scams demanding wire transfers or gift cards are also highly active.
