While the specific scams change everyday, a common warning sign is a letter asking you to send money or personal information now to receive something of value later.
Some common types of high-risk mail you may receive are:
Notices of prizes, sweepstakes winnings, vacations, and other offers to claim valuable items
Personal appeals for money or information from people you do not know
Letters from psychics or religious figures offering to predict or change your future
To report suspicious mail, you can file a complaint online with the Federal Trade Commission (FTC). You can also call 1-877-FTC-HELP (1-877-382-4357) or 1-866-653-4261 (TTY). The FTC cannot resolve individual complaints, but your complaint could help law enforcement detect patterns of fraud and abuse. That may lead to investigations and eliminate unfair practices.
