When people sign up for an online account or buy something from a website, they’re asked to provide their phone number. In most cases, they’ll receive a time-limited code via voice or SMS that they need to input into the system to prove their identity and complete the process. This verification process can help prevent fraud and make sure that the user is who they say they are.
But validating a phone number manually is time-consuming and inconvenient for users. For businesses that want to streamline the validation process, it’s possible to use a phone verification API to automatically verify numbers on a large scale. This helps improve the accuracy of user databases and saves business money.
There are many services that offer a phone verification API. All of them work on the same principle: using real-time network queries to check a telephone number for validity. These services can then return details including location, line type, and carrier for each phone number.
The Verify API from Abstract API is one of the most popular options. It’s available as a RESTful JSON service and supports a variety of languages. This tool is easy to integrate into any application and provides state-of-the-art features that are fast and lightweight. It also allows users to try out 250 lookups for free before starting a paid subscription.
Other phone verification APIs are also available, including the Zolto Verify API. This service uses a database of more than 240 million cell phones to provide accurate results in just a few seconds. The platform can validate both domestic and international phone numbers, and the API supports a wide range of programming languages.
Another popular option is the Numverify API. This is a cloud-based phone number validation service that’s easy to integrate into any app. It’s available in multiple languages and can run up to 30,000 verification requests per second. This tool is capable of verifying both international and domestic numbers, and it offers a free trial that allows developers to try out the service for 14 days.
When it comes to mobile phone verification, the best way to ensure that a number is valid is to check whether or not it’s on the National Do Not Call List. This will help to reduce the amount of spam and fraud calls that can be received at a given number. This is especially important for businesses that take a lot of online orders.
A phone number verification API can also be used to check the accuracy of email addresses linked to a given phone number. This can be useful for fraud prevention, as it can alert businesses to suspicious activity such as a new email address or a change in the person’s name. The frequency at which a phone number makes legitimate purchases or engages in other legit behavior online is also a useful indication of its legitimacy. This information is typically displayed in the AccountBusinessInformation.phoneVerificationStatus field, which can be retrieved by calling accounts.requestphoneverification and passing the phoneRegionCode, phoneNumber and phoneVerificationMethod into it.
