Use cases
MobileValidate use cases are step-by-step playbooks for checking phone numbers and e-mail addresses before you message, call or approve someone. Each one names the checks to run, when to run them, what to do with every answer and what it costs. Unknown answers are never charged, and no check identifies a person.
Fraud prevention
Stop fake sign-ups, OTP abuse and risky contact changes before they cost you.
OTP and sign-up fraud prevention
Check a phone number's line type, live network status and messenger presence before sending a one-time passcode, so fake and high-risk sign-ups are reviewed first.
Read the playbookAccount 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 playbookSaaS free-trial and sign-up abuse
Score SaaS and AI-product sign-ups by line type, reachability, mailbox existence and spam reputation, spot repeated test patterns, and add friction only where the signals call for it.
Read the playbookFintech onboarding: contactability and risk signals
Check that a fintech or lending applicant's phone and e-mail are reachable and consistent before onboarding completes. Contactability and fraud signals, not identity verification.
Read the playbookE-commerce order verification
Check the phone number and e-mail on cash-on-delivery and high-value orders before dispatch, and pick the channel for delivery updates that the customer can actually receive.
Read the playbookTravel booking contact verification
Check the phone and e-mail on a booking: catch typos and fake contacts, cut no-shows, reach guests about changes and see if WhatsApp suits itinerary updates.
Read the playbookMarketplace trust and safety signals
Use phone and e-mail signals at seller and buyer onboarding, before in-app messaging opens up, and when screening promo redemptions, to route risky accounts to review.

Deliverability and cost
Send only to numbers that can receive, on the channel people chose, at the right price.
SMS cost reduction and deliverability
Remove invalid, duplicate, unassigned and unreachable numbers, and route messages people expect over the channels they use, before paying for SMS.
Read the playbookSMS routing with MNP and HLR lookups
For SMS aggregators and CPaaS platforms: route each message by the network that serves the number today, and hold back numbers that are unassigned or unreachable.
Read the playbookNumber checks for OTP providers and SMS resellers
Check numbers before routing OTP and A2P traffic: live HLR status, current network after porting, line type and messaging-app registration, real time or bulk.
Read the playbookWhatsApp list hygiene for marketing agencies
Agencies running WhatsApp campaigns for clients: remove invalid, duplicate and unregistered numbers from opted-in lists before paying for template messages.
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 playbookAppointment reminders for clinics and healthcare
Check that a patient's phone number or e-mail can receive a reminder, and on which channel, before the reminder is due. Only the number or address is sent, never health data.
Read the playbook
Sales and CRM
Catch mistyped and made-up contact details at the form and keep records usable.
Lead 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 playbookLead quality for real estate and insurance
Check the phone number and e-mail on real-estate and insurance enquiry forms in one request, catch fake or mistyped details, and route good leads to the right agent faster.
Read the playbookCRM data hygiene and contact re-validation
Contact data decays as numbers are disconnected and mailboxes close. Re-check phone and e-mail fields in your CRM on a schedule and before every campaign.
Read the playbook
Support and operations
Reach customers, couriers and account holders on a channel that works.
Customer support channel routing
Before a support reply or service notification goes out, check which channels the customer's number and e-mail can actually receive on, then route to one that arrives.
Read the playbookCall-center and spam screening
Screen inbound callers and outbound dialling lists by line type, carrier and live network status and, where enabled, by spam-report reputation.
Read the playbookContactability checks for collections and accounts receivable
Check whether the phone number and e-mail an account holder gave you can receive calls, texts or e-mail before you contact them, with a compliance-first workflow. No reverse lookups, no locating people.
Read the playbookCourier onboarding and delivery notifications
Check that new couriers and gig workers give a reachable mobile number and a working e-mail, and send delivery notifications on a channel the recipient can receive.
Read the playbookCandidate contact verification for recruitment
Check that a candidate's phone number and e-mail can be reached when they apply, refresh stale CV numbers in bulk and send interview reminders that arrive.
