Use cases
Practical playbooks for deliverability and fraud prevention: which checks to run, when, and what to do with each answer.
Account security and takeover risk
Check the phone number or e-mail address a user adds or changes on an account, and step up verification when the signals suggest takeover risk.
Read the playbookCall-center and spam screening
Screen inbound callers and outbound dialling lists by line type and carrier and, where enabled, by spam-report reputation for US, CA and DE numbers.
Read the playbookChannel selection for consented messaging
See which messaging apps an opted-in customer's number uses, such as WhatsApp, Telegram, Viber, iMessage or RCS, and send on a channel that arrives.
Read the playbookLead and form verification
Check the phone number and e-mail address on a lead form in one request, so fake, mistyped and low-quality leads are flagged before sales calls them.
Read the playbookOTP and sign-up fraud prevention
Check a phone number's line type and messenger presence before sending a one-time passcode, so fake and high-risk sign-ups are reviewed first.
Read the playbookSMS cost reduction and deliverability
Remove invalid, duplicate and unreachable numbers, and route messages people expect over the channels they use, before paying for SMS.
