We all know right now peoples are using Truecaller to get caller ID on their smartphones. Trucaller has became leading telephone directory app & Free Caller Identifier for all over the world. The thing is that whenever you install truecaller app on your smartphone device, it will ask for verification of your phone number and hence once your phone number is verified, your contact details would be added to truecaller database. Truecaller has seperate page for de-registering numbers so that your number would not be searchable using Truecaller Number Search.
When you fill up this application, your number will be delisted from Online Truecaller directory.As per this page, If you don’t want your phone number to be searchable in the Truecaller Phone Numbers directory for privacy reason, then you can simply enter your phone number there along with country code and press ‘Unlist’. (i.e. +4690512214). You cannot resubmit your number to the directory. You can choose the reason from the list and you will need to type word captcha verification. When you click on unlist, it will process and remove your number.
From now, your number will not be searchable on Truecaller app or from Truecaller Online website.Another trick for the same is you can deactivate your Truecaller account by login to your Truecaller account and it will remove your details from their website. Second step is to use Truecaller unlist option to remove number completely from truecaller.
