I am explaining what you can do to block No Caller ID calls. The good news is that you can block specific callers/numbers. There are also more and more telemarketers, spammers using No Caller ID because they do not want to be known.

You are receiving these calls because, in the USA, The Federal Communications Commission (FCC) mandates that cellular carriers allow people the ability to block their Caller ID, hence No Caller ID. These calls may also be labeled as Anonymous, Private, or Blocked. You may want to block these calls because you cannot possible identify the number of a caller before answering. Are you getting a lot of calls from unknown callers (e.g., spammers, telemarketers etc) with “No Caller ID”.
