Customer Data Management

From Activation to Retention

Capture accurate data
Check the phone number a user enters in your sign-up process and validate it in real-time to make sure you get the right phone number from the get-go.

Help users enter their phone numbers correctly by indicating errors and invalid numbers in real time. Don't annoy the users by asking them to refill the form afterwards. (They may never return!)

Cleanup your database
Keep your customer database up to date. Customer's phone number is the most important identifier. Perform regular cleanups and update the data associated with phone numbers as it gets easier and easier for mobile subscribers to switch carriers.

Fraud Prevention

Secure Transactions

Reduce failure
Failed attempts are unacceptable when it comes to sending time-sensitive messages such as one-time passcodes (OTP) and transaction alerts. Validate the numbers before texting or calling to ensure successful delivery.

Catch bad actors
Validate the phone number to determine the best way (text or voice) and the best time (country/timezone) to send a critical, timely messages such as one-time passcodes and transaction alerts.
