Does 141 work on a mobile?
Simply type the numbers 141 before the phone number you plan to dial. This is the same system used on landlines but it also works on mobiles. It was first introduced to stop people getting your number when they dialled 1471.
Block your number on a single call
All you have to do is add 141 to the beginning of the number you're calling and the receiver will not be able to see who you are; instead they'll be presented with Private Number or No Caller ID.
This can be done on a per call basis on both landline and mobile devices - for iPhone and Android. If you're not withholding your number permanently, you can use 141 to withhold your number on a call-by-call basis. There is no cost to this service - it's free.
To hide your number for one call, enter 141 before the number you're calling. If you've hidden your caller identity, enter 1470 before the number to show it for that call. If you want to hide your number for an international call, enter 00 instead of + before the number you're calling.
You can ask us to permanently withhold your number, or you can choose to withhold it yourself on a call-by-call basis. To withhold your number on individual calls, just dial 141 before the telephone number you want to call.

After you set up the app, you will want to go to the iPhone settings > Phone > Caller Identification and Block and enable Truecaller. This will allow for Truecaller to use CallKit integration (iOS 14.0 and up) for live spam identification.
While this is not a setting you can access directly from your iPhone, you can use a special code as a prefix to the number you are calling to block your own number. In the UK, if you enter the number 141 before the number you're calling, your number won't be shown.
Both Android and iOS devices let you hide your caller ID, making you show up as No Caller ID, Private, or Blocked to everyone you call.
How do I call back a private number on Android?
Sure, people have the right to block their numbers in order to maintain their privacy, but you have the right to uncover their identity if you need to as well. If someone has phoned your landline, you can dial *69 to call them back. It works the same way on your mobile device, but you need to dial #69 instead.

*82 - Unblocks Caller ID on one outbound call
This star code will unblock your caller ID for a single outgoing call if you have previously used *61 to block caller ID for all outbound calls.
Dialing *68 will disable the Caller ID for the next outbound / external call only. Selecting a line and dialing this feature code will result in a prompt on the phone display as well as an audible message: "Caller ID is BLOCKED for the next outbound call only." We hope you find this new feature code useful!
To do it, just enter *67 before, enter the phone number with area code, then hit the call button. If that doesn't work for you, sometimes #31# before the ten-digit number will do the trick since some carriers like T-Mobile use that to hide your number and name when both would show.
Common “star codes”
*57 - Traces the number of the last incoming call received. *60 - Prevents calls from select phone numbers. *67 - Block phone number on Caller ID systems. *69 - Redial the last number that called you.

How do I change my caller ID name?
To find these options, open the Phone app on your Android, tap the "More" icon (3 dots) in the upper-right corner of the screen, select "Settings," and then "Call Settings." Next, tap "Additional Settings" and then finally select "Caller ID."

Alternatively, you can stop your caller ID being revealed by using the relevant code for your country – 141 from a UK landline, for instance, or *67 in the US. Now you can call the blocking iPhone, and it will ring normally, since it doesn't know you're the person it blocked.
If you can't find an option to block your number or hide your caller ID in your phone's settings, you need to block it directly with your cell carrier instead. Most carriers who don't let you block your number in the device settings let you do so using their own app instead.
How to hide your phone number using *67. The easiest way to hide your phone number is to use the code *67. This allows you to block your phone number so the recipient sees a message like "Private" instead of your name and number when your call is incoming.
Also, some people with Caller ID may choose not to answer calls from blocked numbers. To temporarily unblock your line so your call will be accepted: • Press *82, then dial the telephone number you're calling. Your identity will be shown on the recipient's Caller ID display.
If someone blocks your cell number, can you put *67 before it and text or call them? No - that won't work. The *67 function only stops the person you're calling from seeing the number. It does not make the number invisible to the network's equipment.
