How to Call Without Disclosing your Number

by on September 4th, 2013

Usually when privacy is the concern, there are ways you can use to call anyone anonymously by using available apps for iDevices, Android or PCs. You can even use your smart phone settings to hide your phone number depending on your device in some cases. Almost all smart phones have feature of ‘Block Caller ID’. If you change your phone settings to block caller ID, the receiver phone will display as Unknown Number or Anonymous Call while you call them. This is a secure way to deal with an unknown person or calling back to non-familiar number. But this method will set the device to permanently mask your phone number while you make calls. You can use apps or use tweaks to still call anonymously without changing your smart phone settings.

Tweak Dialing Number

Use *67 before full number to be dialed. By full number I mean number with country code. This method does not depend on smart phone device or platform. You can block your caller ID by simply adding *67 prefix before the number. You must dial country country (e.g. ‘1’ for US) following to *67. The call format will be like *671-XXX-XXX-XXXX.

In iPhone Go to ‘Settings’ > ‘Phone’ > ‘Show my Caller ID’ and turn it off.

In Android Go to ‘Settings’ > ‘Call Settings’ > ‘Additional Call Settings’ > ‘Caller ID’.

While using Windows phone go to ‘Start’ > ‘Settings’ > ‘Phone’ > ‘Caller ID’.

These above settings and tweak may and may not work in your country, so allow us to mention few apps to call anonymously.
