Before you call back
  • If you do not know anyone in Florida, do not call back: a genuine caller will leave a message or send a text.
  • Scammers fake the number shown on caller ID, so a 904 number can hide a caller anywhere in the world.
  • Never give a code received by text or a bank detail to an unknown caller. In the US, calls can be reported at reportfraud.ftc.gov.
