The 650 area code is heavily used for Google account security scams and business listing threats. Callers pretend to be from tech companies to steal your passwords or force business owners to pay for free services.
Scammers spoof Google numbers like 650-203-0000 with convincing American male voices, claiming your account has been compromised from overseas locations like London, Germany, or Norway. They try to log into your account while on the phone, which triggers a real security prompt on your phone, then pressure you to approve it to "secure" your account. They use your approval to take complete control of your Google account. Google will never call you unsolicited about security issues.
"Got a call from 1-650-203-0000. GOOGLE assistant. Telling me my Gmail account had been hacked. Please do this and the other. I did not however the did manage to hack my Gmail account and 15 seconds later tried to hack my Coinbase account."
Bay Area residents report small, unauthorized charges appearing on bank and credit card statements listing "FACEBK," "METAPAY," or "GOOGLE *SERVICES" with 650 area code numbers like 650-543-4800 or 650-253-0000. Charges appear for things like "Google Konami" or "Tic Tok Live" that victims never purchased, sometimes with strange names like "Amari Bowens" or "krempaskyengel," often in identical amounts like $1.07 or $5.01 charged back-to-back. Scammers obtain your card numbers from data breaches and test them with small charges before making larger purchases. These charges can appear on brand new or recently reissued cards.
"Citibank card was repeatedly hit for $1.07 for Google stuff. Closed card, reissued card immediately hit for same amount. Quit Citibank. Last I heard the card was still taking hits."
Robocallers target local business owners with automated messages claiming your Google Business Listing is "at risk of displaying incorrectly" or being suspended, demanding you "press 1 now to check the status of your Google listing." Some ask to verify holiday hours for Thanksgiving or Christmas, while others claim to be from "Google Maps" but hang up when questioned directly. They use your response to sell you unnecessary SEO or listing management services. Google does not make automated calls threatening to suspend business listings.
"This is an important message do not hang up the phone your Google business listing is at risk of displaying incorrectly We've tried numerous times to contact you by telephone so we can check the status of your listing... press one now to check the status of your Google listing if you're the business owner press one now Press 2 to be removed from this list."
Scammers leave urgent voicemails claiming "allegations" have been filed against you or threatening to serve you with legal documents at your home or work. They mention vague "legal proceedings" or a "civil matter," demanding you or your attorney call back immediately, sometimes referencing debts more than four years old. They use these scare tactics to trick you into providing personal or financial information over the phone. Real process servers do not call ahead to warn you, they show up.
"I got a call from 650.292.2410 regarding serving me with court papers to my home or work if I don't call them back to stop the process server."
Robocalls claim your Social Security Number has been "suspended due to suspicious activity" and direct you to press 1 to speak with an agent to avoid "legal enforcement actions" or arrest. The fake agents ask you to verify your Social Security number over the phone, then use it to steal your identity or money. Your SSN cannot be suspended or revoked. The Social Security Administration communicates through official U.S. mail, not threatening robocalls.
"Recorded message saying my SSN has been suspended due to suspicious activity press 1 for more information on this case."
Callers with foreign accents claim to be from Microsoft, McAfee, or Apple support, saying your computer's firewall was turned off or your iCloud account was breached at 3:15 AM. They demand you go to your computer immediately and give them remote access to "fix" the non-existent problem, with caller ID showing "Help Desk" or generic names like "Glen King." They use remote access to install ransomware and steal your personal information or money. Microsoft and Apple do not make unsolicited phone calls about computer problems.
"Individual said he was calling from Microsoft to inform us that our computer had been compromised at about 0315 AM and our antivirus security software had been turned off. He could fix it if we would go to our computer now and give him access. We did not comply with his wishes and hung up."
Scammers send text messages or make automated calls claiming you have an outstanding doctor's bill, sometimes from specific local doctors like "Dr. Beth Moore," threatening to report you to collections for debts you do not actually owe. The messages contain malicious links or eerie voicemails asking you to confirm your name by pressing 1 for yes or 2 for no. They use your response or clicked links to steal your payment information or install malware on your phone. Medical providers will not initiate contact about past-due accounts through text messages with strange links.
"Phone number texted me with multiple messages saying I owed money to a location where I did get a Covid test, and that they were going to report me to collections. The link looked very legitimate! Called the company who was named and I have no outstanding balance with them."
