Spam calls from 533? What to know
Seeing repeated missed calls from 533 numbers you don't recognize is the classic signature of neighbor-spoofing robocall campaigns. The caller isn't necessarily anywhere near you — spoofing software displays whatever digits the campaign chooses. Never call unknown numbers back; look them up first, and report unwanted calls to the FCC to build the public record.
