Verification Code

Verification Code is a system used by an organisation to validate the action like form filling for sign up and to keep them free from spammers, Robots. In this post, I have discussed the available option to verify security code and how to use them and keep your information safe.

Instant messaging applications like WhatsApp, Hike, and WeChat are using the same system to get  verification code by sending and one time password OTP to the registered mobile number. If the user entered the code sent to his mobile number correctly then this is considered as well read subscription to their service.

In general, whenever a person is signing up for a new service or filling up the form online it is a mandatory step to validate whether it's the real human who is filling up the form or it is an automatic software or a robot which is filling up the form. Hence, the user will be required to verify his identity by entering numerical value or character that shown on the screen inside the verification box.

  2. Text

    Verifying the user by entering a piece of text displayed on the screen is another brilliant method for avoiding invalid, spam and automated signups. The image here gives you an example of text or App verification code.

    In this process, the user needs to look into the text displayed in the email nearby and have to enter exactly the same values without even changing the casing of the letters. After clicking on the submit button, the value will be validated and if correct the user can proceed.

  3. Numerical Value

    If the number entered is invalid then the user will not be allowed to proceed for further activities compare to the textual value entered entering the value with the help of numerical value is easy for the user and it is user-friendly too.

  4. OTP (One Time Password)
    Verification Code

    Authenticating your identity using OTP also called as a one time password is a real-time validation that is done exclusively on accessing an account using a registered email address or phone number.

    This method of authentication is highly used in internet banking processes and validation of instant mobile applications like WhatsApp Hike and We Chat during the process of installation.

Can I Receive Verification Code Via Email?

Yes, you can receive the one time password or the code used for verification to your email address. However, it is not the case every time. 

There are several scenarios where the code or the authentication factor is sent only to your email addresses or to your phone number based on the kind of transaction you are making.

If you are using a service that is registered with your email address, yes the code can be sent to your email address. Similarly, if you are using a service which is registered with your mobile number as a primary factor then the code will not be sent to your email address rather it will be sent only to your phone number. 

The intention behind sending a validation code is to verify that you have active access to your mobile phone and not to your email address.


To summarise about the verification code topic, it is the best and effective method to avoid loss of information and information theft, misusing data that is processed online for signing up.

Several fraudulent activities are being stopped because of validating the identity of the users at the right time. Any security breach that is detected during the process of financial transaction or any confidential login credentials must undergo a verification process. Either using a text, image or One Time Password system.
