- [ ] Check Caller Identification Apps ### Explanation Caller ID aka Phone Contact Book apps are applications designed to identify incoming calls by displaying the caller's number and, when available, the name associated with that number. They help to identify contacts, protect against fraud and spam, highlight incoming calls from "business". Of course, they usually collect databases of phone numbers and names (tags), using users' data (being crowdsourced contact books), and even provide lookup interface. Having only a phone number, you can check such apps to find a name or additional attribution information used as a part of contact name in contact lists. Also, some 3rd-party platforms allow to conduct reverse search by a name (tag) providing list of phone numbers containing search keywords. ### Input - phone number - name/tag ### Output - name/tag - phone number ### Examples - [Using Phone Contact Book Apps For Digital Research](https://www.bellingcat.com/resources/how-tos/2019/04/08/using-phone-contact-book-apps-for-digital-research/) ### Tools - [Getcontact](https://www.getcontact.com/) - [Truecaller](https://www.truecaller.com/) - [Numbuster](https://numbuster.com/en/) - [Sync.me](https://sync.me/) - [eyecon](https://www.eyecon-app.com/) - Caller ID - CallApp - Some Telegram bots with functionality of reverse search (EyeOfGod) ### Types {{ business | technical | behavioural }} ### See also - {{internal links to similar techniques}} ### Weakness [[SOWEL-9.
