No more spam! Learn how to block calls from a specific DDD

We are increasingly plagued by unwanted calls, telephone spam. It is collectors, telephone and cable operators, banks, insurers, alleged charities, or simply blatant scams that disrupt our activities and exhaust our patience.

Sometimes they just call to hang up as soon as you answer. At other times, they are insistent: you pick up, decline an offer, and call you back five minutes later, as if nothing had happened. And it's no use asking to stop, they don't stop. Never.

Luckily, we have the technology by our side: there are several apps that allow you to filter calls (call screening), automatically blocking spam numbers based on a database continuously fed by the users themselves.

Still, some calls may pass because Call Centers use multiple origin numbers, whether through local, other state or even international calls. And the numbers change constantly.

But if you pay attention, you may begin to realize commonalities. For example, that all calls come from the same DDD code. So how about blocking this whole DDD instead of number by number? Here's how to do it in the top three call blockers and get your peace of mind back.

But first, a warning

Blocking an entire DDD a cannon shot. No one using this DDD can call you, even if it's a legitimate call. So think carefully before you enable this feature so as not to be out of touch with a relative, colleague or customer.


TrueCaller, from Scandinavian True Software Scandinavia AB, perhaps the most popular call blocker in the Android world: is installed on over 100 million devices, according to Google Play.

In addition to automatically blocking numbers known to fill the bag, TrueCaller can also block calls from a specific DDD. The problem is that this feature is a bit hidden. So much so that, until writing this article, I did not realize that it existed. And I'm a long time user.

TrueCaller "sizes =" (max-width: 806px) calc (100vw - 24px), (max-width: 995px) 782px, (max-width: 1216px) calc (2 * (100vw - 30px) / 3) + 15px - 24px), 782px "src =" "srcset =" TrueCaller-w782.jpg 782w, 596w, jpg 450w, 336w, 300w "class = "lazyload" />
In TrueCaller, DDD lock is hidden / AndroidPIT
<p>Click the menu with the three lines in the upper left corner of the screen and click Settings> Block> My Block List. Now click the + button in the bottom right corner of the screen and choose Lock a number of numbers. At the top of the next screen, choose Numbers starting with.</p>
<p>In Number type the DDD you want to block, in parentheses. For example, I get many mysterious calls from DDD 81 (Pernambuco), so to block them digit (81). Click Lock and you're done! Some calls may come with international syntax, with +55 followed by the code. So I need to repeat the operation and also block +5581.</p>
<p>The hassle of TrueCaller is the free version supported by ads (which appear in the middle of your call list), and the app insistently offers an upgrade to the PRO version, which costs $ 5.90 per month and has more features and no features.

Gogolook's Whoscall is a popular alternative to TrueCaller, with some advantages: among them the lack of interface advertisements and a cheaper subscription plan, at $ 4 a month. In addition, it has a much simpler call blocking system.

On the main screen click the Lock button in the bottom right corner of the screen. Tap Block calls from other DDDs and choose the codes you want to block from the list. That simple.

Whoscall "sizes =" (max-width: 806px) calc (100vw - 24px), (max-width: 995px) 782px, (max-width: 1216px) calc (2 * (100vw - 30px) / 3) + 15px - 24px), 782px "src =" "srcset =" Whoscall-w782.jpg 782w, 596w, jpg 450w, 336w, 300w "class = "lazyload" />
Whoscall comes with several pre-set lock options / AndroidPIT
<p>In addition, Whoscall has a number of pre-set blocking options, such as Block Carrier Calls and Block Bank Calls, in addition to private number blocking options and outside contacts in other apps.</p>
<p>A very useful feature is Protected Recharge, which detects if you are not being charged for extra services such as news, virus protection, or missed call identification, which often magically appear on your bill, eating credits or making the bill more expensive.</p>

Who calls – Whoscall

Mr. Number

The third option is Mr. Number, from Hiya. It offers features similar to TrueCaller and Whoscall, with a clean interface and no ads even on the free version. I also liked the possibility of seeing comments that other users left on the blocked numbers, just tap on the number in the call list.

In contrast, it was less efficient than TrueCaller in auto blocking, letting more calls pass in the period I used it. And there is no Portuguese translation.

Mr. Number lets you see what other users have said about a number / AndroidPIT

Here, the option of blocking an area code is easier to find. Click on "Block List" at the bottom of the screen, the "+" button and "Numbers that begin with". You will see a field with +55 already filled in, so just type the DDD. In the previous example, 81. Click on "Block" and enjoy the silence.
