Have you ever received texts or calls from numbers you don’t know? A company you have never heard of sent you a message. You might wonder, how did they get my phone number?

In today’s generation, phone numbers are more often shared than we realize. Sometimes, we even share them without even thinking about it. Let’s break down the ways people and companies get your number.

Most probably, you provided it to them. Here’s how you might have provided them with your number:

  • You might fill out an online form.
  • You signed into a contest or offers.
  • You enter it while creating an account for games, applications, or websites.

There are many other resources for finding your number. Some of the remaining are phone books, Public records, friends and families, and scam bots.

What Are the Common Uses of Your Phone Number?

Your phone number is used in many simple ways every day. Phone numbers not only carry risks of misuse but also provide security. Let us explain it to you.

Many websites and applications ask for your phone number to send codes. This is called two-factor authentication. Verification codes are used to prevent unauthorized login and keep your account safe.

Restaurants and stores might ask for your phone number to send you receipts and bills. While in schools and other organizations, you might sign up for alerts, updates, and work. Some companies might use your number to send you special offers and ads. They might even call and text message; that’s called marketing and advertising.

They might pretend to be from a delivery service, bank, or government office. They may make phishing attempts to extract personal information or scam call to you.

Some people might even scare you or threaten you by calling you again and again. They might send you threatening or upsetting messages on a regular basis. Even your number could have been used to sign in for fake accounts or services. That can lead to unexpected charges, threats, strange text messages, or emails.

In rare cases, someone might use your phone number to pretend to be you. They might even contact your mobile, friends, and family, even trying to steal from you. This shows why it’s essential to protect your phone number and share it wisely.

Phone Number As a Gateway: Tech-Focused Angle

Do you know your phone number may be a gateway for hackers and scammers? The phone number you have works as a key to entering your digital life. There are many majors to do so; let’s unfold together:

SIM Swapping:

What actually happens in this scam is that someone tricks your phone company. They make the company believe and move your phone number into their SIM card. Once they do that, they get your calls and messages and even gain access to your accounts. This can lead to bank theft or account takeovers.

Hacking Two-Factor Authentication 2FA:

Many people use their phone numbers to authenticate or verify, which is also called 2FA. If someone gets your number by any means, they can receive those codes. Then, they can break into your social media, bank accounts, and email—even hack your phone and take over it.

Reverse Look-Up and Tracking:

Some websites let people search for your numbers to find out who they belong to with some details. The details might even be your personal details, address, and other private information. They might extract your data and phone number or make stolen mail to scam you.

Access Messaging Apps:

Some apps, such as WhatsApp, Telegram, Snapchat, and Viber, need you to log in using your phone number. After gaining access to your phone number, someone might pretend to be you and message your contacts. Your phone number connects more than your phone, your whole digital identity.

Avoid Posting Your Number Publicly:

Remember never to post or comment on your number on social media or public websites. To protect it, keep it private, even in reviews and feedback.

You can use a secondary number or virtual phone number to sign in on websites or for work-related tasks. Services like Google Voice or Burner apps can help you protect your number.

Block and Report Spam:

If you receive spam calls or text messages, block scam calls, numbers, and connections. You can even report the situation to your mobile carrier or local authorities.

After following all these simple steps, you can lower the risk of using your number in a harmful way.
