Phone number validation helps you ensure that users have entered valid numbers that are capable of receiving calls and SMS messages. This process improves user experience by simplifying contact lists and eliminating invalid, disconnected, or reassigned numbers. It also eliminates the costs of sending SMS messages to these inactive contacts, resulting in higher deliverability rates and overall engagement rates.

The most common use cases for phone number validation include verification, identity checks, and identifying the type of mobile or landline. It is important to note that there are different rules for each country, and these can impact the validity of a phone number. For example, the US has a specific set of rules for determining whether or not a phone number is valid. This includes checking if it has the proper area code, prefix, and suffix. It is also important to ensure that the number does not exceed the length of a country’s telephone network.

Unlocking the Potential: How a Phone Validation API Can Improve Contact Information Accuracy

Invalid phone number formats can break integrations, cause data issues between platforms, and create duplicate records. Therefore, it is crucial to implement phone number validation in your apps.

The most popular phone number validation platforms are available in both free and paid versions. These services are often included in SMS marketing platforms and provide an easy-to-integrate API for implementing phone number validation into your applications. These APIs will check if a number is valid, formatted correctly, and can receive calls and text messages. They can also check if a phone number is associated with a prepaid service provider, which is useful for identifying possible risky behaviors.
