TIP 01
Don't call back blind.
Especially if the safety label is suspicious or worse. Robocallers use one-ring tactics to bait callbacks to premium-rate numbers. If you didn't recognize the caller, don't return the call until you've identified them.
TIP 02
Verify independently.
If the caller claimed to be from your bank, the IRS, a delivery service, or a tech-support team — hang up and call the official number on the back of your card or printed on their .gov site. Never use a number the caller gives you.
TIP 03
Report it everywhere it counts.
Add your report on this page, file with the FTC at reportfraud.ftc.gov, and report robocalls to the FCC consumer complaints portal. Reports compound — yours helps the next person.
