Your Complete Guide To Phone Validation


Whether it’s a big business that requires another layer of security or a startup that deals in streamlining communication between different services, phone validation is an essential element of the business world. It requires a thorough understanding of what it is, how it works, and why it is crucial.

With businesses becoming more complex in their models and services, security issues like cyberattacks, breaches, and scams are also becoming prominently common. Phone validation is one of the many methods used in the industry to ensure that these attacks and breaches are appropriately tackled.

What is Phone Validation?

Let’s consider why someone would want phone validation. Suppose you have a business that collects the numbers of its customers for messaging them about products later on or for customer service. Suppose that a customer inputs a number that isn’t theirs. It could altogether be a false number that doesn’t even exist. Some scammer could be trying to bypass your sign-up stage to gain access to your services. 

But with phone validation, you can not only confirm if a phone number is live and belongs to the respective customer, but you can also weed out scammers and bar them from your business. As a result, the data that accumulates in your database is authentic, usable, and valuable.

Phone validation is the process of checking the validity of a phone number. This process improves the quality of a list by fixing the formatting issues and appending data points like country, carrier, line type and makes sure that a user is asked for explicit consent before they are being contacted on their number. 

There are three main types of validation. Each class provides a different level of security validation with distinct data points. Let’s look at each type and consider which one is the best for you.

How Does Phone Validation Work?

There are three types of phone validations.

  • Number validation
  • Network validation
  • User Validation

Number Validation

In number validation, you save time by validating the phone number and checking to see if it is approved and assigned by a given telecom authority to a carrier and line type. This type gives you the following data points: 

  • Validity
  • Format
  • Line type
  • Region
  • Carrier

This type of validation covers all the numbers used worldwide. It’s fast and efficient. It’s cheap, costing as low as $0.1 per 1000 validations. 

Network Validation

In-network validation, the carrier is contacted to inquire about the current state of the phone number without contacting the number itself. This will reveal whether the number is active or not, the carrier’s name and whether they’re roaming. It provides the following data points:

  • Active
  • Original Carrier
  • Ported Carrier
  • Roaming Carrier

User Validation

User Validation occurs by sending the user a PIN message to confirm if they’re indeed the person in charge of the number. It also validates user consent.

Why Is It Important?

You might ask yourself if your business needs phone verification at all. After all, your company has been functioning all this time without it just fine, hasn’t it? So why is it important to validate phone numbers now? 

First of all, phone number validation gives you optimum client satisfaction. If a number is not validated, you might reach the wrong number and won’t contact the client at all. They won’t understand that you made an error. They will blame you and therefore give your company a bad image, leading to a loss of potential and long-term clients. By ensuring that you’re working with the right validated information, you remove that risk entirely and improve customer satisfaction.

Another important aspect is cost saving. Phone validation is a short-term expense that saves you from long-term costs in the future. If you’re sending messages to the validated numbers from the get-go, you’re improving your business’s reach and not wasting time and money trying to procure the correct numbers from a third-party seller. 

You can improve your marketing campaigns by using validated numbers. Targeted marketing through SMS paired with validation will ensure that you reach the relevant recipient every time.

Phone validation saves time by validating the number at the point of entry. If you’re contacting the wrong people, it’ll take up your time to apologize for the mix-up, and then look for the correct number from scratch. 

In the case of delivery businesses, most companies ask for a phone number so that they can use it to deliver parcels properly. Without validated numbers, goods might get delivered to the wrong address or not delivered. With validated numbers, your delivery business can reach the customer.

Key Takeaways

You can save money, time, and resources while improving your business’s security by adding phone validation, ensuring that each number is active and belongs to the right person.
