Phone Verification

Validates phone numbers to ensure their accuracy and authenticity.

The Phone Verification API validates your phone numbers to protect your database from invalid, toxic, and undesirable phone numbers. We help you avoid a damaged sender reputation by flagging those invalid phone numbers and do-not-contact lists before you have a chance to use them.

Real-time Phone Verification allows you to send us batches of up to 10 phones at a time.

Combats fake accounts: Verifies phone numbers are real and associated with active users, reducing the risk of fraudulent registrations, transactions, and bot activity.

Reduces bounces and failed deliveries: Ensures accuracy of phone numbers in databases, improving marketing campaign effectiveness and customer outreach efforts.

Automated data cleansing: Saves time and effort by automatically verifying and updating phone numbers within existing databases.

Boosts engagement with targeted communication: Verifies contact information for effective SMS marketing campaigns and customer service communication.

Compliance with regulations: Meets industry-specific regulations requiring phone number verification for certain activities.
