How to Make a Call from a Hidden Number
Universal Method
Before dialing the phone number you want to call, simply type #31# followed by the number itself. For example, to call 0501234567, dial #31#0501234567 — this way, the call will come from a hidden number and your number will not appear to the person receiving the call. This method works across most mobile networks in Israel, including Cellcom, Partner, and Hot Mobile.
Android Devices
Open Settings > Apps > Phone (or "Calls") > Additional Settings > Caller ID > and select Hide Number. From that point onward, all calls you make will appear as hidden. Note that the exact menu path may vary slightly depending on your Android version or device manufacturer.
iPhone Devices
Go to Settings > Phone > Show My Caller ID and switch the option off. Your number will then be hidden in all outgoing calls. If the option appears greyed out, your mobile carrier may be restricting this setting — contact your provider directly for assistance.
Landline Phones
You can try dialing #31# before the number. If that doesn't work, try *43 before the number. Keep in mind that this action may involve additional charges depending on your service provider.
These methods hide your number only for a specific call or until you change the setting — they don't provide permanent anonymity.
Responsible Use of Hidden Numbers
It's important to use this feature responsibly and ethically. Using a hidden call for malicious purposes — such as harassment, threats, or violating someone's privacy — is dangerous and illegal. Phone harassment from a blocked number can seriously harm the victim and disrupt their daily life.
In Israel, the law treats phone harassment as a criminal offense, allowing authorities to identify and prosecute the harasser. According to the Ministry of Justice, repeated harassment through any communication means — including phone calls — can lead to formal criminal proceedings. The Israel Police actively handles complaints related to anonymous phone harassment, and victims are encouraged to document every incident and report it without delay.
Therefore, hidden numbers should be used only for legitimate reasons, like protecting your privacy during a personal conversation — not to harm others. Misusing hidden calls may lead to legal action or even criminal charges. If you are on the receiving end of such calls, the Israel Consumer Council offers guidance on your rights and the steps you can take to protect yourself.
Identifying Hidden Numbers
Today, several apps in Israel help fight phone harassment from hidden numbers. The leading app in this field is Traceback, which enables users to quickly identify unknown or hidden callers and protect themselves from unwanted calls in the future. Traceback also stores timestamped call records, which can serve as documented evidence if you choose to file a formal complaint with the authorities.
Thanks to tools like these, people gain more control over who's trying to contact them — even when the number is concealed — helping them maintain peace and personal security. In a world where digital privacy is a growing concern, having the right tools is no longer optional — it's essential.
Receiving a hidden call once felt uncertain, but now, with Traceback, every such call becomes an opportunity to find out who's really behind it.
