unknown number
Value not determined
An unknown number is a phone call from a caller whose identity cannot be determined, either because the number is blocked, unlisted, or genuinely unrecognized.
When your phone displays "unknown number," the caller has deliberately hidden their information or the network cannot retrieve it.
People often let such calls go to voicemail out of suspicion they're spam or scams.
I never answer unknown numbers anymore.
