Prefill
What is Prefill?
The Prefill module provides fast and trusted identity autofill, powered by the Identity Graph. With only a few pieces of personally identifiable information (PII), Prefill can automatically return complete and verified identity details such as name, date of birth, and address.
This capability:
- Accelerates onboarding
- Reduces manual entry
- Enriches user profiles
- Blocks synthetic or mismatched identities at the door
At the core of Prefill is SocureID, a graph-resolved identifier linked to a real person, confirmed across credit, alt-data, government, and behavioral sources. If inputs can’t resolve to a SocureID, no data is returned.
| Enrichment | Input fields | Signals returned | Coverage | Best for |
|---|---|---|---|---|
| Prefill | - First name + last name - Plus one additional PII signal (SSN/ITIN, phone + DOB, email, or address + ZIP) |
Best-matched identity record (full name, DOB, address, etc.) | United States (all listed inputs) International (Phone + DOB) | Internal use cases such as back-office pre-population and enrichment for agent review or decisioning logic |

Note:
Prefill is an enrichment step that accelerates form-fills with verified identity data, while Advanced Prefill adds real-time risk intelligence to stop fraud and maximize conversion. For details on Advanced Prefill setup, refer to the Advanced Prefill Solution Guide.
What you can do with Prefill
Prefill is designed to enhance onboarding flows, improve user experience, and enrich customer data. Developers typically integrate Prefill in the following scenarios:
- Onboarding Optimization Minimize friction during account creation by auto-populating identity details (such as name, DOB, and address) from just a few PII inputs like phone or email. This reduces manual typing and improves completion rates.
- Verified Autofill Replace self-entered data with trusted, graph-resolved identity attributes. Prefill ensures that returned details are accurate and consistent across sources, reducing errors from typos or incomplete submissions.
- Profile Enrichment Expand and enhance existing customer records with additional, verified attributes. Prefill can surface associated emails, historical addresses, or linked phone numbers, helping you build a more complete picture of your user.
Unique Features
- Scalable identity resolution: Leverages Socure’s large-scale identity graph to resolve individual identities with high precision and minimal conflict.
- Multi-source data ingestion: Ingests signals from credit, alternative, behavioral, and government data sources to enrich profiles and return verified, high-confidence matches.
- Decision-level transparency: Every verification decision includes detailed source attribution, ensuring trust in autofill results.
- Dynamic match optimization: Adapts match logic based on input type, regional factors, and use case—balancing speed, accuracy, and fraud resistance in real time.
- Cross-journey identity linking: All results are anchored to a persistent SocureID, enabling consistent resolution and fraud prevention across channels.
- No partials, no guesses: Only returns results when all inputs resolve to a single verified SocureID.
- Synthetic-proof: Blocks synthetic or fabricated identities to ensure autofill is always accurate and trustworthy.
- Conflict handling: If input signals disagree, Prefill returns nothing, eliminating the risk of populating incorrect identity data.
