Voter registration scams are now ubiquitous. Here's how to spot them.

Did you receive a text message saying you are not registered to vote? It could be a scam.

According to the National Association of Secretaries of State, voter registration fraud is one of the three most common scams during an election cycle, alongside scams involving political donations and falsified polls. Scammers typically contact their victims by phone, text message, or email (and sometimes in person) to tell them they need personal information to update voter registration forms.

In Shasta County, California, the county clerk and election officials warned last week that a text message asking recipients to click a link to register to vote was a scam. Officials said clicking the link could trigger malware and put the victim’s personal information at risk.

Across the country, election officials in Lake County, Florida, issued a similar warning in March. County Supervisor Alan Hays asked residents to “be vigilant this election cycle for political scams that can mislead unsuspecting individuals and lead them into a frightening experience that can be difficult to overcome,” local media reported.

Clerks in Salt Lake City and San Francisco have also issued similar warnings.

The National Association of Secretaries of State says voters should check whether the communication is coming from local or state election officials and be wary if anyone asks for payment to fill out voter registration paperwork.

The Federal Trade Commission (FTC) recommends reporting any unsolicited text messages or calls from someone claiming to need your Social Security number or personal or financial information to register to vote. If you send your personal information to someone you don’t know and you think you’re being scammed, you can visit the FTC’s Identity Recovery page to report the scam.

The FTC recommends contacting your local election office or consulting the U.S. Election Assistance Commission’s National Voter Registration Form to determine if your state requires your Social Security number for voter registration.
