WhatsApp trick: so you can know if someone has your number without you knowing

But thanks to the profile photos, the information we can add or the statuses, WhatsApp It has also adopted the characteristics of a social network. In addition to being able to know what others are doing, the app allows us to manage the digital relationship with our contacts.

Therefore, as with other social networks, we like to know who saves our phone number as a contact and who does not: old friends, ex-coworkers, ex-partners, family members, etc. WhatsApp does not offer this information, but there is a trick that will allow us to know it.

The key is the broadcast list tool. The steps are simple:

We create a new broadcast list. We send any message through this list. We wait until the recipients can read the message. Then, click on the message and on the 'Info' option. There, WhatsApp will show us the phone numbers of those who have received and read the message, also in the case of people who have our WhatsApp number as a contact even if they are not included among those we save in our agenda.

If we have reached this point, It could be because we don't want that person to see our data. profile or other information. To solve this privacy problem, we can choose two ways.

One is to choose the most restrictive options in 'Privacy', that is, select 'Just my contacts' either 'Nobody' in the 'Last seen time', 'Profile photo', 'Info' or 'Status' options.

But sometimes it may happen that we have no problem showing all or part of that information to third parties, but to some specific ones. In that case, it would be best block that person on the app. If it is not in our agenda, we would have to add it to later formalize that block by opening a chat and clicking on the buttons at the top until we find the option 'Block'.
