If you run a business with a phone number validation API, you can boost your deliverability for SMS and voice calls as well as ensure that sensitive information only goes to the right person. In addition, using such a service helps you to keep your customer data clean, which in turn increases sales and improves user satisfaction.
When a customer signs up for an account or purchases something from your website, you need to make sure that the phone number they enter is valid and can be reached. Otherwise, you may end up spending time and money on a marketing campaign that won’t reach its target audience. Furthermore, non-functional numbers can cause dissatisfying conversion rates, making it harder to measure the effectiveness of your marketing and sales strategy.
Using a phone number verification API, you can prevent such problems by verifying each phone number in real time to make sure that it is a valid and active phone number. This saves your business a lot of time and money by ensuring that your messages or texts reach the right people.
In addition to detecting whether a phone number is valid, a good phone number validation API will also detect the correct line type (landline or mobile) and define the country code. This helps your business to remain compliant with the FCC Telephone Consumer Protection Act and ensures that all customers are contacted in the right manner.
The best phone number validation APIs are easy to integrate into your business, enabling you to check the validity of a phone number in real time and provide users with accurate and useful information. Some phone number validation APIs also offer additional functionality, such as determining the location of the phone number, or the name and city where it is registered.
This makes it easier for your business to personalize and target your marketing campaigns. If your customers know that you are only targeting them with relevant messages, they will be more likely to engage with your brand and return to it again.
A good phone number validation API will also return a range of other valuable data points, such as carrier information and the handset status (active or inactive). Some services even offer fraud analysis to identify risky numbers, which can be especially helpful for businesses that accept payments online.
A good phone number validation API will offer a free trial so that you can test it out before integrating it into your business. It should also support various channels for two-factor authentication (2FA) delivery, including SMS, voice, email, TOTP and push. Moreover, it should support retry buffers so that your business can avoid accidentally spamming the same number or hitting rate limits in the process. This is important because humans are impatient, and if you try to send a code to a wrong phone number too many times, the user will lose patience and potentially leave your website or app. A good phone number validation API should also allow you to store a user’s preferred channel for 2FA delivery so that it is delivered in their preferred method of communication.
