What is "Notifiable"?
An incoming call with a "Do Not Notify" number is an indication that a phone number cannot be notified due to restrictions imposed by telecommunication companies, lines, or other factors.

The Dangers of "Do Not Call" Calls
Un-notifiable" calls are too dangerous, and if you don't reject them, you could be victimized!
Possible Leakage of Personal Information
If you are receiving many blocked calls, there is a possibility that your personal information has been leaked. There are opportunities to hand over personal information in casual everyday situations, such as entering a sweepstakes or applying for a gift, but there are also malicious companies that leak or sell this information to outside parties.
We also often hear of incidents where company databases are hacked or information is stolen by exploiting security vulnerabilities. If you receive many unanswered calls, consider the possibility that your personal information has been compromised.
Possibility of being used for fraud
Some blocked calls may be used as a means of phone fraud, such as bank transfer scams. The person on the other end of the blocked call may be trying to set up a bank transfer scam. It is unlikely that someone trying to scam you in the first place would notify you of their phone number, so there may be some underlying reason.
Possibility of sales calls
Calls for sales purposes, such as sales calls and solicitation calls, are often blocked from the outset. Generally speaking, blocked numbers are not good for sales efficiency because callers often distrust such calls. However, if a phone number is notified, it is possible to register the number in the phone book and set "reject calls from this number. Companies specializing in sales calls often call the same phone number repeatedly for various purposes. To avoid this problem, some companies use blocked numbers.
Possible criminal intent.
In some cases, blocked calls are used as a means of checking to see if someone is home before a burglar or robber enters the house. Since not answering the phone means that you are not at home, it is dangerous not to answer the phone just because it is a blocked number. You should consider some countermeasures, especially if you have a landline at home.
