Yes, there are third-party apps like TrapCall, Hiya, and Truecaller that can help identify, block, or unmask No Caller ID or spam calls. However, the effectiveness of these apps may vary and might require a subscription.
Private numbers, blocked, and restricted calls can usually be traced. However, unknown, unavailable or out of area calls are not traceable because they don't contain the data needed for a successful trace.
In Australia, dial *10# if you get phone service through Telstra. If you get service through Optus, dial *69 on a landline.
A private number is when a caller intentionally blocks their number from showing on caller ID. They're used to hide the identity of callers, and they can appear on your phone as 'Private Caller', 'Restricted', 'Blocked', 'No Caller ID', or other similar variations.
In the end, it is prudent to err on the side of caution and not answer calls from unknown numbers without first verifying the caller's identity. This will aid in safeguarding your privacy and security. Telemarketers and scam callers are also likely to use no called ID.
No Caller ID means that the caller intentionally blocked their ID. On the contrary, an unknown caller means the Caller ID was not recognized even though it was provided. The best way to handle this is to turn on the option to block unknown callers on iOS.
With TrapCall, you can unmask these blocked numbers and find out exactly who's calling you from No Caller ID. That means their phone number, name, and even their address. Plus, with TrapCall you can even blacklist the unmasked phone number to prevent them from continuing to harass you.
If the incoming call shows Unknown or Unknown Caller, the caller's phone or network might be set to hide or block the Caller ID for all calls. By default, your outgoing Caller ID number and name will display when the recieving party has Caller ID enabled.
Caller ID is set by the caller, not the receiver. With regards to your incoming calls, your Contacts app matches and displays the number of incoming calls when the caller has chosen to show their number. Incoming calls will not be matched to your contacts list when a caller has chosen not to show their number.
On accessing 'Block numbers', you'll find a subsection labelled 'Block unknown/private numbers'. Adjacent to this label is a toggle switch which is currently off. To activate call blocking for unknown or private numbers, you'll need to switch the toggle to 'on'.
