USE CASES

Reach real people, whatever you're building

From signup forms to sales pipelines, see where phone validation fits and what it saves you.

Lead generation

Sales teams lose hours calling numbers that were never going to connect.

Check every lead’s number when it arrives, so your reps only spend time on people they can actually reach.

  • Validate numbers as soon as a form is submitted
  • Flag VoIP, disposable and fake-looking numbers
  • Add line type, carrier and location to each lead
  • Call mobiles first, route the rest to email
New lead comes in
  1. Lead submits form
  2. Number validated
  3. Valid → sent to sales
  4. Risky → marked for review

User registration

Fake signups inflate your numbers, abuse free trials and waste OTP messages.

Validate the phone number on your signup form before you create the account or send a verification code.

  • Catch invalid and made-up numbers instantly
  • Spot VoIP and disposable numbers used for throwaway accounts
  • Only send OTPs to numbers that can receive them
  • One API call from any signup flow
Someone signs up
  1. Enters phone number
  2. Checked in real time
  3. Valid mobile → send OTP
  4. Invalid → ask to correct

Fraud prevention

Bad actors rely on numbers that are cheap to get and easy to throw away.

Use the 0–100 risk score on every lookup to decide what to accept, what to review and what to block.

  • Risk score with plain-English reasons
  • Flags VoIP, disposable and premium-rate numbers
  • Detects repeated and sequential digit patterns
  • Set your own thresholds for review or blocking
Decide with the risk score
  1. Number checked
  2. Low risk → accept
  3. Medium → extra check
  4. High → block

SMS & voice campaigns

Every message sent to a dead number or a landline is money gone.

Clean your list before you send, then import it into whichever SMS or calling platform you already use.

  • Remove invalid numbers before the campaign
  • Separate mobiles from landlines for SMS
  • Standard E.164 format your provider accepts
  • Upload a CSV and download the cleaned list
Before you hit send
  1. Upload contact list
  2. Every number checked
  3. Mobiles → SMS list
  4. Invalid → removed

Contact management

CRM data decays: numbers get disconnected, typed wrong or saved in ten different formats.

Validate your existing records in bulk and keep new ones clean as they come in.

  • Bulk validate your database with a CSV upload
  • Add line type, carrier and location to each record
  • Standardise every number to one format
  • Re-check old records whenever you need to, via CSV or API
Clean up your CRM
  1. Export contacts
  2. Bulk validate
  3. Enriched & formatted
  4. Import back to CRM
