How to Block a Number in Android in a Few Steps

Like an IP address on the internet, the phone number is a unique identifier assigned to you. It connects people to the intended recipient without worrying about someone picking up on the other side. The phone number is valuable; it’s used to bombard you with SMS marketing, phone calls, or other offers that you never signed up for. Android phone manufacturers give the option to block a number.

Why Do You Need to Block a Number

Marketing today is invasive. It does not uphold your privacy or consent. Online ads are a perfect way to demonstrate how advertising agencies track your activities and target you based on interests. Social media platforms and their cross-site trackers follow the breadcrumbs left by you. It’s not a coincedence that an ad pops up on your Facebook feed after you were searching for that item elsewhere.

While online advertisement tries to be discreet in approach, telemarketing continues to annoy people. Depending on where you live and the laws surrounding spam calls and text, you could face dozens of ads per day. It depends on how easily your phone number is accessible on the internet.

How to Prevent Spam Calls and Text

Like your email address, the phone number is valuable data for advertisers. It’s collected as part of a data collection drive that uses bots to gather phone numbers or email addresses from public places online. These bots scour places such as forums to find the information and record them for advertising.

Whatever you post on the internet remains on the internet. In today’s world, where data is the most valuable asset, the less you share, the more life will be personal. Sharing phone numbers on public forums is inviting spam texts and calls.

Even if you are leaving the phone number on a marketplace forum or group, there is a smart way to do it. Bots typically collect numbers, so breaking numbers into words makes it a bit difficult for the bots to read. For example, instead of writing 6804980, it’s better to write SIX EIGHT ZERO FOUR NINE EIGHT ZERO.

But it’s not just spam calls that you need to worry about; Phishing attempts are a potential danger. Phishing is a fraudulent technique that often uses urgency as a way to lure people. Normally, phishing targets a large number of people, but concentrated attempts like Spear Phishing requires diligence and data on the target. It’s where your phone number comes into play. If you receive an email that appears to be from one of the vendors, your phone number may be used to verify to add legitimacy to the whole process. The collection of phone numbers for Spear Phishing or Whaling Attack is part of Pretexting.
