Database Validation is the Sumsub's solution to comprehensive customer personal data and identity document validation, which safeguards business operations from risks related to synthetic identity fraud as well as illegal or underage use of services in more than 50 countries worldwide.

It works by either asking the user to submit a few unique identifiable elements, which are used to instantly extract their complete personal information, or by matching user identity and document details against authoritative sources to establish their legitimacy. The result ensures that businesses bring only trusted customers onboard, while also meeting the applicable AML/CTF requirements and maximizing their conversion levels.

The overall solution helps regulated organizations meet their national regulatory requirements on verifying customer data against reliable sources as well as determining that they are an active, registered taxpayer. At the same time, it serves as an additional security element, ensuring that the submitted user information and ID are genuine, reducing both the potential risks and additional resource needs related to document, as well as synthetic identity fraud.

These values make Database Validation a reliable extra security layer that enables businesses to increase their level of regulatory compliance and identity verification assurance.

The supported data verification methods for this solution are:

Data Enrichment — retrieving comprehensive user identity data based on unique personal identifier verification against official government, banking, and credit sources. The extensiveness of identity data returned depends on individual product capabilities.
1x1 Matching — screening user’s identity data against a number of reliable databases until it matches either one or two of the sources in their country. The range of sources available for screening depends on individual country coverage.
Validity Check — validating the status, ownership, and legitimacy of the applicant's identity data and document against official government sources. The exact response returned via this verification method depends on individual product capabilities.

CURP status codes

When verifying a CURP (Clave Única de Registro de Población), RENAPO may return different status codes depending on the individual’s registration history. These statuses indicate whether the CURP is valid and active, or has been deactivated due to various reasons such as administrative changes, death, or judicial orders.

Active statuses (AN, AH, RCC, RCN) represent valid CURPs that can be used for identity verification.
Inactive statuses are considered invalid and must be rejected during verification.

CURP status	Description	Registration status	Comments
AN	Normal registration	Active	–
AH	Registration with homonymy (duplicate name handling).	Active	–
RCC	Registration updated with changes that affect the CURP key itself (e.g., identity or registry data changes).	Active	CURPs that had a modification impacting the key.
RCN	Registration updated with changes that do not affect the CURP key.	Active	–
BAP	Cancelled due to apocryphal/invalid supporting document.	Inactive	CURPs generated with fraudulent or invalid documentation.
BSU	Cancelled for non-use.	Inactive	CURPs with no activity since issuance (not revised, printed, or used). To reactivate, a request must be made through the CURP module.
BD	Cancelled due to death	Inactive	–
BDM	Cancelled administratively.	Inactive	CURPs deactivated at the request of the issuing authority.
BDP	Cancelled due to adoption.	Inactive	CURPs replaced with new identity data after adoption.
BJD	Cancelled by judicial order.	Inactive	CURPs deactivated following a court ruling.
