Top 5 Reliable Phone Number Validation API for Your Next Product

Spread the Knowledge

The first goal of every business is to gather leads and nurture them until they become customers and possibly loyal customers.

As part of this process, they collect personal information and contact details such as email addresses and phone numbers. 

However, they often don’t offer valid ones, which means you waste time and money having ineffective leads. 

Therefore, there are today validators that check that, for example, a phone number is active.

The web is filled with many phone number validation APIs, so choosing the right one can be a challenge.

As a result, in this article, we will examine some of the best phone number validation APIs, so that you can integrate them into your product and no longer waste time on useless leads.

So let’s get right into it.

What is a phone number validation API?

The phone number validation API is a solution that checks whether or not a phone number is active. Additionally, it can provide useful parameters, such as:

  • Location – city or region of origin
  • Type of phone number (cell phone or landline)
  • Phone carrier type

Where to use phone number validation API

It is possible to use a phone number validation API for a variety of purposes and situations. Here are some of the most common ones.

  1. Websites

Nowadays, every website has an online contact or subscription form, which allows you to collect information about visitors and customers and make it easy for them to contact you. 

If placed with the purpose of gathering valuable information and leads, forms must capture relevant and valid information, like phone numbers and emails. As a result, integrating a phone number validation API will allow you to ensure that numbers captured in your online forms are correct and valid.

  1. Apps

Similar to websites, apps might include forms that are purposely inserted to capture contact information from potential customers. Once again, you must ensure that these are valid and accurate, and a phone number validation API can help.

  1. CRM

A customer relationship management strategy is a way for a business or organization to manage customer interactions, usually by using data analysis to analyze and study a large amount of information. In order to ensure this information is valuable, a phone number validation API can check whether the numbers taken over the phone are valid and entered correctly by employees.

Benefits of using a phone number validation API

Many benefits can be attributed to a phone number validation API, which makes it convenient to use. Some of the most notable are outlined below.

  1. It saves you money

Consider running promotional campaigns and spending money on useless leads and invalid or inactive numbers. You will have to pay for all those leads once you begin a marketing campaign, for instance, and they won’t be of any use to you.

  1. Enhances conversion rate

By having valid and genuine leads, you are more likely to have a good conversion rate as people who are really interested in your product will be more likely to purchase it. Consider instead sending promotions to invalid phone numbers; it probably won’t yield the results you want.

  1. Prevents fraudulent entries

You can use phone number validation APIs to fight spammers and fraudsters who do not provide their phone numbers during signup. This adds an extra layer of security to maintain a clean and safe user base.

  1. Increases customer satisfaction

By keeping leads and customers informed throughout the process, you can also improve customer satisfaction, retention, and repeat order rates.

  1.  Improves campaign analysis

You can determine the success of your marketing and sales campaigns directly by how many phone calls you make. You can still get an incorrect picture of how well your strategy is working if a certain percentage of the phone calls go to the wrong numbers.

By getting a clean phone list, you can make sure that each call you make goes to the right person, which will optimize the results of your campaign.

  1. Reduces typos and errors 

A phone number validation API allows users to correct their contact data immediately right at the point of sign-up. You will be able to improve the quality of customer phone numbers in your CRM and ERP systems.
