The US Postal Service is warning Americans about various holiday scams this year, including “smishing,” phishing, and counterfeited postage. The U.S. Postal Inspection Service (USPIS) advises customers to be cautious of online sales offering fake stamps, emails or texts that may contain viruses, and package theft.
To avoid these scams, the USPIS suggests keeping computer and cellphone software up-to-date, using signature confirmation for deliveries, and being aware of counterfeit stamps being sold online. By taking these precautions, consumers can protect themselves from falling victim to holiday season scams.
