International phone number formatting
All phone numbers must use E.164 format: a + prefix, followed by the country code, followed by the national number with no spaces, dashes, or parentheses.
Example: A United Arab Emirates mobile number 50 123 4567 with country code 971 becomes +971501234567.
Known limitations
- Dashboard phone field length: The RiskOS™ Dashboard phone input field may truncate numbers that exceed the expected length for a given country. If you encounter this issue when entering international numbers through the Dashboard, submit the phone number via the API in E.164 format instead.
- Country code required: Phone numbers submitted without a country code cannot be validated. Always include the full E.164 number including the
+prefix and country code. - Unsupported regions: If a phone number originates from a country not listed in the coverage table, Phone Risk may return limited or no results. The evaluation continues with other available enrichments.
Industries it fits
- Financial services: Account opening, fraud prevention, progressive onboarding
- E-commerce: Checkout fraud prevention, return abuse detection
- Payments: Reduce risk in P2P transfers and high-value transactions
- Gaming & media: Stop fake accounts, bonus abuse, duplicate accounts
- Telecom: Validate new phone numbers during profile changes and SIM/line updates
- Call centers & CX: Real-time trust checks for number changes and OTP delivery
- Plus other digital onboarding and fraud risk workflows
Business and operational outcomes
1. For fraud and risk teams
- Identify high-risk phone numbers in real time.
- Reduce OTP-related ATO by validating the destination number’s risk and ownership.
- Leverage multiple model scores per call for testing and migration.
- Gain transparency with reason codes for both risk and correlation.
2. For growth and onboarding teams
- Progressive onboarding: Establish trust early with only a phone number (optionally name/address for correlation).
- Reduced friction: Let good users through while blocking risky numbers.
- Adaptive signals: Multiple models tuned for different fraud/risk trade-offs.
3. For support and operations
- Fewer escalations: Clearer signals reduce review queues.
- Transparent explanations: Reason codes help agents understand outcomes.
- Lightweight integration: Minimal required fields keep implementation fast.
Performance considerations
- Fast responses: Sub-second latency on average in production.
- Always available: 99.99%+ uptime with global redundancy.
- Built for scale: Supports tens of millions of risk checks per day.
- Smart models: Multiple models can run in parallel to optimize accuracy and fraud capture.
Boundary conditions
- Phone number + country are required: correlation accuracy improves when first and last name are also provided.
- Multiple models: Test challenger vs. production models to tune thresholds.
