At this page you can set Truecaller to replace digits on a phone number that you will search for. This could be a phone number you search for during manual search or incoming/outgoing number lookup.
The first input fields describes digits you want to replace or remove from the beginning of a phone number. Simply enter digits you want to replace. In this case I added 01# because all incoming calls on my phone starts with 01# because of my corporate phone switch system.
If I leave the second field empty, it will simply remove 01# from the phone number. I could replace it with something else such as my country code which is +46.
The next input fields describes what I want to remove or replace at the end of the phone number.
In this case I added *202 because our corporate system also adds *202 at the end of all incoming phone numbers. In this case *202 will be replace with nothing but I could also add something here if needed.
Press save and you are done!
