US carriers allow subscribers to block spam messages with simple syntax

Specifically, users just need to type “OFF” and send it to Verizon's service center to block messages sent from email-to-text addresses, an activity that is identified as spam by more than 80%.

Spam messages have been a "burning" problem in the US in recent years.

Last year, the Federal Communications Commission (FCC) issued a warning about the rise in text scams. The agency said complaints about unwanted text messages increased from 5,700 in 2019 to 14,000 in 2020 and 15,300 in 2021.

The FCC also said in its report that spammers want recipients to “engage” with them. So, like robocalls, text messaging systems also try to tap into users’ fears or frustrations, such as overdue bills, lost packages, bank account errors, or legal issues.

Some scammers aim to steal subscriber money, others simply want to collect users' personal information or confirm that the phone number is "active" to conduct future scams.

By regulation, the FCC prohibits the use of automated call centers to send text messages to customers' cell phones except in emergencies or with prior notice.

In early 2023, US authorities also issued the first set of rules on scam messages, requiring mobile service providers to block some automated messages (robotexts) that are determined to be “highly likely to be illegal”.

Verizon offers a fairly broad text message filter for subscribers who don’t want to turn off the email-to-text feature. The carrier says customers can re-enable the feature by texting “ON” to the operator.
