Most Common Area Code 820 Scams

The 820 area code is often used for health insurance scams and Amazon impersonation calls. Fraudsters try to sign you up for fake plans or claim unauthorized orders on your account.

Health Insurance "Open Enrollment" Scam

A caller named "Jessica" claims to be from a health insurance provider and says "open enrollment has been extended." She leaves voicemails even after being blocked. They use your interest in health coverage to sell you fake or overpriced insurance policies you don't need. These calls bypass blocked numbers to keep harassing you.

"Blocked number sometime ago but somehow they still get to leave voicemail even tho my phone doesnt ring. Jessica with some kind of health ins scam. the open enrollment has been extended so you havent missed out on too expensive ins that you dont want but we'll keep calling you anyway..."

Amazon Impersonation Scam

Someone calls claiming to be "associated with Amazon" and creates urgency about your account or an order. They use this fake emergency to steal your personal or financial information. Amazon never calls customers to ask for personal details or payment information.

"Called on the pretense of being associated with Amazon."

Vague & Persistent Unsolicited Calls

Callers use slightly different numbers to bypass call blockers and refuse to identify themselves or their purpose. Some send vague texts like "Hello" to verify your number is active. They use your response to confirm your number works for future spam campaigns. Legitimate companies identify themselves immediately.

"Calls from this number or very similar number over and over again. I keep blocking the new variations but they keep coming, latest one in the series is: . 820-732-9362"

Unsolicited Political Surveys

Callers from a "Research Company" want to conduct "Political Surveys" and specifically state "We are not selling anything" to make the call seem harmless. They collect your personal opinions and information to build profiles for marketing or political targeting. You never have to participate in any survey.

"We are not selling anything; We are a Research Company which conducts in Political Surveys, we only want your opinions."
