The reason is, a 1,000 non-functional and valueless leads won’t do your business any good, but a handful of quality ones can surely make a huge impact. And if you can turn those leads into loyal customers, your company can shoot up the ladder real quick. That’s the importance of having valid leads. There’s always a talk about tools that validate email addresses since collecting email leads is the most common. However, what about phone numbers? How do you validate those? That’s the question, but fortunately, there are answers to that as well. In fact, there are quite a lot of options. We’ll be looking at some of the best phone number validation APIs in this article so that you can integrate them into your product and say goodbye to worthless leads. Before we dive into the list, let’s know some of the many benefits of using a phone number validation API.
Saves you a lot of money 💵
Imagine running an SMS campaign that sends out messages to about 1,000 recipients, but only 300 of them are actually valid and functional. This means you’re paying money to send out SMS to 700 phone numbers that are either invalid or not working. Let that sink in. Using a phone number validation API, you can easily avoid that and save a lot of your hard-earned money in the long run.
Gives you better conversion rates on your campaigns 📈
No matter how great your promotional campaigns are, if there are non-functional phone numbers in your database, you’re always going to have inaccurate and dissatisfying conversion rates. And as a business, you surely do not want that. A phone number validator will make sure the analytics are steady, as there will be only valid phone numbers who’ll receive your SMS and voice call campaigns.
Prevents fraudulent entries, thus saving you time ⚠️
These APIs will help you fight spammers and fraudsters who don’t provide their phone numbers during signing up. It adds an extra level of security to maintain a clean and safe user-base, which would allow only genuine customers to fill in their entries. Now it’s time to have a look at the compiled list of the APIs.
