This is further validated against the Central Identities Data Repository (CIDR). This procedure builds user identity assurance and protection at the system level.

E-KYC is an automated method that permits businesses and corporations to identify their client's customers without a physical engagement. Users obtaining GST e-registration can submit required documents and information via the Internet, which simplifies and accelerates the verification process by eliminating the need for any hard copy documents.
