One of the best ways to maximize the security of your account is through phone number verification.

What Is Phone Number Verification?

Before we explore the benefits of phone number verification, let’s clarify what it means. Phone number verification is the process of confirming the accuracy and legitimacy of a given phone number. This process entails calling or texting the specified phone number to receive a verification code. The user has to provide this code to validate their identity. After validation, they are given access to their account. This method will actively reduce account takeovers, fraud, and other unethical behavior. Businesses can make it harder for hackers to access accounts by confirming that a particular phone number is active and actually in use by a real person.

Why Does Phone Number Verification Matter?

Phone number verification safeguards user accounts, prevents fraudulent activities, and fosters trust that cannot be overstated. Take a look at why phone number verification matters: 

  • Reduced Account Takeover: Fraudsters take control of user accounts for different malicious intents. Verifying phone numbers prevents scammers from reaching prohibited information.
  • Lowered Risk of Fraudulent Accounts: Verifying phone numbers safeguards genuine users from malicious activities such as spam or financial fraud. It protects the overall authenticity of online platforms.
  • Commitment to Security: Phone verification fosters trust and confidence among users. It encourages them to participate actively in online interactions and transactions.

What Are the Dangers of Invalid Phone Numbers?

The security of an account can be seriously compromised by invalid phone numbers. If a user provides an incorrect or invalid phone number, it can lead to unauthorized access and fraudulent activities. 

  • Unauthorized Access: A user entering an incorrect or fake phone number during registration creates an opening for unauthorized access. Scammers easily gain control of the account and cause dangers to the overall account security.
  • Fraudulent Activities: Invalid phone numbers can facilitate various types of fraud. Attackers might use them to bypass security measures and steal someone’s identity or financial information.
  • Security Breaches: Invalid phone numbers weaken the overall security of online systems and platforms. There’s a higher chance of unauthorized access and potential data breaches without proper verification.
  • Compromised Verification:  If the provided phone number is invalid, users won’t receive the verification code, which renders the 2FA process ineffective. It leaves your account vulnerable to unauthorized access.
  • Impact on User Trust: When users encounter invalid phone numbers on a platform, it raises concerns about the overall security practices. It leads to losing trust and confidence in the platform’s ability to safeguard user information.

How Does Phone Validation Work?

Users are asked for their phone number when they try to log in or register for an account. A phone number validation API is used to confirm that the entered number is accurate. This API looks at the number’s format, country code, and whether it is a legitimate mobile or landline number, among other things. To verify that the phone number is operational and capable of receiving messages, the API sends a text message to the number.

Does Phone Number Verification Guarantee Account Security?

Phone number verification adds a layer of protection to the accounts. It confirms the ownership of a phone number associated with the particular account. As a result, it helps businesses prevent unauthorized access to an account.

  • Phone verification makes unauthorized access much more difficult with one-time codes.
  • It makes it harder for fraudsters to create fake accounts for malicious purposes like phishing or scams.

The security of an account can be seriously compromised by invalid phone numbers. If a user provides an incorrect or invalid phone number, it can lead to unauthorized access and fraudulent activities. This is why it is crucial to validate phone numbers at the point of entry.
