You can call it (do not forget to dial 141 before the number to hide your number), or search it on Google.
Yes that is true. BTW that is not a question it is a statement
In the U.K, we have a system that when you dial 1471 after your last call it can tell you the number, however, there is a simple way for prank callers to hide there number. If so, the number is not traceable by us. I don't know if this is the same around the world.
If you're in the United States, dial *67 before you type in the number (example: *67123-456-7890)
On any GSM mobile phone, dial #31# before the number to suppress display of your caller ID information.
From a landline phone press *67 then the number From a cell phone this will only work sometimes, but there is often a setting on the phone to show or hide your number. You could also try *#30# or *#31# or *31# or #31# followed by the number. This works with some cell phone providers.
In the US, dial *67 to block and *82 to unblock your Caller ID from being sent.
You can hide the caller ID display a few ways when you need a little privacy. One method is to dial *67 before the number you are calling. Another way is to make arrangements with your service provider.

Yes, if you dial *67 (or equivalently 1167) to block your outgoing Caller ID, and then dial *69 (or equivalently 1169) to call back the last incoming number, it should show up on the other person's phone as "blocked" or "number withheld." In order for *67 to work, it should be dialed first, before any other "star codes." For example, to block outgoing Caller ID and also cancel call waiting, you should dial *67 *70, not *70 *67. The order shouldn't matter, but it sometimes does. In the US and Canada, you can dial 11xx instead of *xx, if you are using a rotary or pulse-dial phone.
This will depend on the phone model and your phone carrier. You can call them to find out how to hide your number.
You can with every phone, but not texting you can hide your number when calling someone though, by putting 141 before the persons number you are calling.
