5 Reasons Why You Need To Do Number Verification


Some time ago we briefly introduced the number verification feature, which is really useful when trying to validate or confirm operations initiated via some other channel, like a phone call or a web site with a simple SMS.

By taking advantage of this mechanism you will be able to enhance the overall security of your web site and services, and make your customers happier by creating the sense of confidence and trust they serve with a very low cost per text message.

In this post we are going to dig a bit deeper into the reasons and use cases where being able to verify a mobile phone number becomes a must.

Confirm Customer Phone Number

A pretty much self descriptive use case, but not less important. Whenever a new customer signs up for your service, opts in to one or more of your marketing campaigns, or just updates his or her information in your website, it is kind of mandatory these days that you have a way to actually confirm their phone number.

This has actually two purposes: on one hand, you can be sure that the customer didn’t make a mistake and that you will be able to contact him directly when in need. But on the other hand, it will also protect your customers by making sure that you will not be delivering sensitive information like passwords and financial information to another person.

Password Recovery

If a customer forgets a password needed to log in to your website, you can send an OTP (One Time Password) directly to their mobile phone, that can be temporarily used to regain access to the account and reset the password. This mobile phone number should be already verified (like stated above) to be sure that your customer will be able to receive and no one else can gain access to it.

Two Factor Authentication

Many big companies like Google, Facebook, Amazon, and banks in general are using this feature to improve the security for their users. Two Factor Authentication (also known as 2FA)  raises the bar for the login credentials by also requiring a code sent by SMS.

When your customers try to login to your website, they will be required to enter their login credentials as usual (like the username and password), but after this preliminary information is validated, a text message will be sent to their mobile with a code that they should enter as part of the login process. They won’t be able to login without the correct username, password, and code.

This is a nice way to protect highly sensitive information from the wrong people.

Customer Service and Customer Care

Once you have a mobile phone number confirmed for a customer, your business become limitless, and so is your customer.

By using A2P  integrated into your CRM or other systems you will be able to support self service features for your clients, like requesting an account balance, retrieve payment or debt information, but also trigger specific actions like opening support tickets, order new products, and pay by credit card.

Financial Transactions

Banks are the biggest users for this one. When a client requests a transaction in a website (like a money transfer) they will receive an SMS with a code to their mobile number  that they must enter in the website before being able to actually confirm the transaction.


Using these features will enhance your business and the relationships with your customers at a very low cost.

In this day and age security is a serious matter and your customers will really appreciate the opportunity of feeling safer while conducting business through your website. But also, being able to truly confirm the mobile phone number of a client will give you the chance to introduce new and amazing capabilities to your own systems like self service.
