Huge time saver! I wish we set up this type of phone and email verification sooner so we had cleaner data, but thankfully we're protected now going forward with Abstract's APIs.

FAQ about Abstract's
Phone Validation API

What is the phone verification API?

Abstract's Phone Validation API is a simple yet powerful REST API that takes a phone number and returns whether or not it is valid, as well as additional information about the phone number, such as its country and sometimes city / region of origin, as well as information like phone number type and carrier. These checks can be done asynchronously or in real-time. By verifying phone numbers via API, you can help keep your sign up and other such flows clear of fake phone numbers and other data and ensure only correct users or numbers continue.

How often is database for the phone number verification API updated?

We utilize several databases of numbers to ensure that that we have expansive coverage of not only every country, but also every type of telephone number, such as landlines, cellular phones, toll free numbers, and more. Our systems regularly ingest this data and cross reference it to ensure it's correct. Various updates to the data are made on a daily basis, and substantive updates to the phone data set are also made on a weekly and monthly basis.
