Has a long lost relative reached out for some help? Is USPS texting you about your missing package that you never sent? These are almost certainly imposter scams.
Imposter scams are one of the most common modern scams. The scammer may call, text, or email their target pretending to be someone you can trust.
Government Imposter Scam
