When the phone rings, do you see who it is or do you see "No Caller ID" instead? Not seeing who's calling can be frustrating, but unknown numbers are quickly silenced! This wikiHow article walks you through silencing unknown numbers and figuring out who that caller could be on iPhone.

Things You Should Know

  • Silence unknown and callers without ID in "Settings > Phone > Silence Unknown Callers."
  • "No Caller ID" calls are from callers who overtly took extra steps to hide their number from you, so you can't see who's calling, and most likely aren't calls that you need to answer.
  • Get in touch with your carrier for more blocking options or download a third-party app.

    If the switch is green and pointing to the right, the feature is active and any unknown or blocked calls will be redirected to your voicemail. [4]
    • Some people suggest that you can also add the phone number 000-000-0000 to your contact list (name them something like "Do Not Answer") and then block that number .

    In the past, Verizon users found out the hard way that iPhones inherently could keep their number private , even when they were calling their spouse or friends. [5] To hide the iPhone's number, you simply go to Settings > Phone > Show My Caller ID and toggled it off.
    • A code like *67 or #31# entered before a phone number to call would also hide your caller ID, so the person receiving the call would see "No Caller ID." [6]

    These callers could be telemarketers trying to sell you something, an organization looking for donations, or a normal person who doesn't want you to see their caller ID. [7]
