Use SSN Check when you need to verify a US customer's Social Security Number against authoritative records.

It fits account opening, US KYC onboarding, CIP checks, and fraud reduction workflows.

What customer data does SSN Check verify?

SSN Check verifies:

• First name
• Last name
• Social Security Number (SSN)

It also checks whether the SSN has been legitimately issued, is active, and is not linked to a deceased individual.

Is SSN Check enough for KYC or CIP?

SSN Check supports US identity data validation.

For stronger identity verification, SSN Check is usually complemented by checks such as Document Check, Identity Check, Proof of Address Check, and AML Screening Check, depending on your risk model and regulatory requirements.

Does SSN Check replace document verification?

No.

Use Document Check when you need government-issued ID verification and document fraud analysis.

Does SSN Check verify date of birth or address?

No.

SSN Check verifies the customer's first name, last name, and Social Security Number.

If you also need date of birth or address verification, use Multi-Bureau Check or eID Check, depending on your workflow.

What is the difference between SSN Check and Multi-Bureau Check?

Use SSN Check when you need US-specific Social Security Number verification.

Use Multi-Bureau Check when you need broader identity or address verification across multiple countries and data sources.

Many US onboarding flows use both:

• SSN Check for direct SSN validation.
• Multi-Bureau Check for broader identity and address corroboration.
