Phone number validation for Apps



A strong user base is essential for the prosperity of your business. The key to the continuous growth of the user base is protecting your business and the customers from fraud. A study shows investments made to prevent malicious activities against users can increase the average value of the user base by 44%. Phone validation is considered the most reliable and effective way to apply vital security measures to an account.

Connecting a valid and unique phone number to each end-user account ensures the protection of the brand, the web and the users from any sort of fraud and ensures their confidential information remains safe and secure throughout.

What makes phone number validation significant?

Valid data holds significance in each field of marketing, but this validity holds higher value in marketing through phone and email marketing as these two forms of marketing are at its peak of growth and their ROI depends majorly on quality data. Phone validation is becoming an industry standard as 9 out of 10 companies are securing their customers through mobile phones. Benefits they get:
  • Confirms the identity of end user: The mobile of a user is an intelligent, connected device to confirm the identity of a user through a lifetime. Before a user gets registered using a phone number, you can get the whole profile of that user by just knowing which mobile device is related to that phone number. Once you have a validated a phone number and identified the mobile device it is related to, you have established a global trust anchor with the end-user for secure access throughout the account lifecycle.
  • Avoids abuse through bulk account creation: Creating multiple accounts on a web application has been quite common. Some people do it for taking advantage of any offer, some want to keep an eye on the world remaining anonymous and some just do is coz it is allowed. These actions mess up the data in a long run. By adding the feature of identification through phone, a web app/ brand can cut off such abuse and see to it that valid users are able to create an account.
  • Builds user-trust with two-factor authentication: Recent surveys suggest that 80% of the users remain worried about their online security and insist on adding an extra layer of security. A two-factor authentication through phone verification provides the business the additional layer of security to ensure the accounts of customer are safe and secure. If any time your account is being logged in from an unknown device, a new location, the user is informed immediately. An OTP (one time password) is sent on the phone which when verified makes the log-in successful.
  • Secure account recovery: The channels with insecure account/password recovery methods are ones exploited the most. If not monitored properly, can be very costly for your business as the average cost for a password-related helpdesk inquiry is over $10 and with a self-service password reset solution 70-90% cost can be saved.
  • Prevention of fraud: Real time verification of phone numbers through security intelligence and reputation scoring you can get valuable data attributes and risk assessment. This helps establish a confirmation that the account registrant is not a bot or spammer.

How to validate phone numbers for your app?

Any web application has two options – either develop a code within the app or outsource a phone validation tool for your app.

There are multiple ways in C#, C++, to validate phone numbers, but it requires a lot of development. With so many quality tools available in the market you can go ahead with a much easier, thorough and cost-effective method i.e outsource the phone validation service for your app. Not only does it shorten the development cycle but makes phone number validation more reliable.

Instead of trying to add custom snippets of code its easier to use phone validation API to connect to a data validator. Highlighting the error when a user is entering a wrong, incomplete or landline number, ensures only valid data to enter the eco-system.

Phone validation API simplifies your codebase, saves you money, creates a better user experience, and makes your app more efficient since you’re outsourcing some data processing.
