FAQs

Prefill is Socure’s identity autofill capability that enriches user data from minimal PII (e.g., name + one identifier such as phone, email, SSN/ITIN, or address). It returns a best-matched identity record (full name, DOB, address, etc.) to accelerate onboarding, reduce manual entry, and enrich customer profiles. Prefill does not perform additional risk or device checks.

Advanced Prefill builds on Prefill by combining autofill with real-time risk intelligence. With just minimal inputs (e.g., phone + SSN last 4), it can:

• Enrich identity data
• Validate against Socure’s Identity Graph
• Incorporate OTP flows
• Add device risk signals to block fraud while maximizing conversion

For implementation details, see the Advanced Prefill Use Case Guide.

• Use Prefill for back-office workflows, pre-population, and agent review scenarios where speed and enrichment are the priority.
• Use Advanced Prefill for consumer-facing onboarding and signup flows where you need both autofill and strong fraud prevention.

No. Prefill remains valuable for enrichment and internal workflows. Advanced Prefill is best when you need identity autofill plus fraud prevention in a customer-facing flow.

This happens when inputs could not be resolved to a single identity, or when inputs pointed to multiple or conflicting identities.
In such cases, Prefill returns an empty object ({}) rather than a partial or ambiguous match.

No. Prefill only returns data when all signals resolve to one trusted identity.
It will never return partial or inconsistent results.

This is expected and usually results from:

• Thin or limited credit files
• Privacy-restricted data sources
• Provisioning or configuration limits

If Prefill cannot confidently resolve inputs—or detects a synthetic identity—it returns an empty object ({}).
No error is thrown, and clients should handle empty/null responses gracefully.

Typical response times:

• U.S.: 250–400ms
• International: Under 4s

Prefill is designed for form autofill and identity enrichment.
Verify and Verify Plus are designed for compliance-grade CIP/KYC coverage, including partial SSN handling.

Yes. Workflows can be configured to return only required attributes.

By default, Prefill outputs:

• First and last name
• Date of birth
• Up to 3 phone numbers
• Up to 3 addresses
• SSN or national ID

Returning subsets (e.g., only address or name) reduces data exposure and optimizes pass rates.

Yes. Depending on the input PII and account provisioning, Prefill may return:

• ITINs
• Full SSNs
• National IDs (for international users)

If you display it to your consumer and ask them to confirm it, then it becomes consumer-submitted data subject to your internal policies.

Yes. With Advanced Prefill, B2C flows are supported where users can review and edit prefilled data.

Requirements include:

• Proper consent language in the client UI
• Compliance and carrier rules followed
• Best-practice UI guidelines and T&Cs applied

Prefill is powered by Socure’s Identity Graph, which aggregates and resolves identity data across multiple trusted sources:

• 2,800+ enterprise customers spanning 40+ industries
• Telco data for real-time phone and device intelligence
• Credit bureau data for financial and historical context
• External and third-party identity sources

This multi-source foundation enables Prefill to deliver verified, high-quality identity attributes with consistent coverage.

Prefill will return no data.

• The entry is flagged internally and may be removed from the identity graph.
• Clients should log or flag these events for future analysis.
