What is unknown number meaning?

The meaning of an unknown number refers to a phone call or text message received from a number that is not saved in the recipient's contact list. The caller's identity is unknown and therefore the intention of the call or message may be unclear. Unknown numbers may be associated with telemarketing, scams, or illegitimate business practices. It is important to exercise caution and avoid providing personal or sensitive information to unknown callers. To identify unknown numbers, there are various tools such as reverse phone number lookup services and caller ID apps available.
