How to block number that is NOT a contact in WhatsApp (unknown)

Normally, to block a contact in WhatsApp you have to go to Application Settings, Account, Privacy, Blocked Contacts and use the “Add contact” button at the top. Now this only works if the contact is saved in your phonebook.

If you have a chat with the number

To block a Unknown number in WhatsApp, or that is not a contact, there are several ways. If you have a chat with that number, the “Block” option is available on the same screen or from the menu (three-dot button) at the top, “More” and then “Block”. If it is a company account you will see the button directly in the same menu.

If you got a call

If the number has called you, go to the WhatsApp call log, tap on the call, menu button at the top and then “Block”.

When you have no conversations or calls

If you do not have any chat or call with that contact, you have to force the appearance of a chat window to have the “Block” button. This is easily done with the same trick that is used to send a WhatsApp without adding the number.

To do this, open the web browser on your device and enter the following URL:

wa.me/numero

You must replace “number” with the phone number you want to block. Put it in international format. For example, if it is a number from Ecuador 0990123456, you must enter it like this 593990123456, where 593 is the country code for Ecuador. Unlike adding a number in WhatsApp, here you should not use the “+” symbol or the “00” before the number.

If the number is correct, you will see the “Send Message” window and tapping on it will open a chat window from where you can block the contact in the way indicated above.

Report

In addition to blocking a number, WhatsApp will give you the option to report it. This is how you tell WhatsApp which number is sending spam or spam messages. The company does not specify what action it takes if it receives a reported number.

Unlocking

Whether it is a contact or not, once blocked you will find it in the list of blocked WhatsApp contacts (Settings, Account, Privacy, Blocked Contacts), from where you can unblock it.

If you have a chat open you can also do it from the chat menu, or send a message, which will give you the option to unblock. The message will not be sent. You must confirm the unlock and touch the send button again.

Conclution

This covers the possibility of manually blocking a number on WhatsApp, whether you have it in your contacts or not. The only thing that the application would lack would be the possibility of blocking any unknown or anonymous number, something similar to what the Android phonebook offers. This way you would guarantee only messages and calls from your contacts and avoid unpleasant surprises.
