It is possible to know who has your WhatsApp number in their contacts, in case people add your number without you knowing who they are. The instant messenger has a feature that allows you to find out which users have included your number in their phonebook and, from there, identify them and/or block them if necessary.
How to find out who has your WhatsApp number
WhatsApp has no native tool that allows find out who added their numbers to contacts, and that are not part of your list. There are several situations in which this can occur, such as:
- An ex who didn’t remove his contact;
- A company that has your number and added it to send messages;
- A person who got your number from someone on your list.
To find out who has your number, do the following:
- Open WhatsApp;
- On iPhone, tap “Broadcast Lists”, “New List”.
On Android, tap “More” (the three dots), “New broadcast”;
- In the list will appear numbers without identification, usually grouped in the character “#”.
These contacts are not on your list, but they do have your number on their lists.
To find out who these people are who have your number in their contact list, open their profile and check if personal information is available. If a user has enabled the privacy settings, data such as avatar, name and last login time may not be available or otherwise restricted.
In that case, the only way left to find out who the person is is to get in touch with them, by text message, voice or the old-fashioned way, by making a call; if you don’t want to have contact with such people, just block them on WhatsApp.
