SMS sender ID

SMS sender ID is the short name, like a header with letters, shown as the sender of a business text. It helps but does not prove a message is safe.

SMS sender ID: An SMS sender ID is the short name or code that appears as the sender of a business text, instead of a normal mobile number. Banks and companies register these headers. A header looks familiar, but scammers can still imitate a similar-looking one.

Genuine bank and service messages usually come from names made of letters, often with a short suffix, rather than a ten-digit number. That is one clue. A message from a plain mobile number claiming to be your bank or a government department is much more suspicious than one that comes from a registered header. Remember that the sender name is a clue, not proof, and it can look very convincing.

Do not rely on the header alone. Scammers register lookalike names, and phones sometimes group their messages into the same thread as real ones. Judge the content too: urgency, a link, a request for an OTP or a threat. When in doubt, open the official app yourself and look for the same notice there. A quick check in the real app takes less than a minute.

Tips

• Treat a bank message from a normal ten-digit mobile number with extra suspicion.
• Even with a familiar header, do not tap links asking for logins or OTPs.
• Check the same alert inside the official app before acting.
