DigiLocker

Users need to possess an Aadhaar number, a unique identifier proving one's identity, to use DigiLocker. During registration, user identity is verified using a one-time password (OTP) sent to the linked mobile number.

The beta version of the service was rolled out in February 2015, and was launched to the public on 1 July 2015. Storage space for uploaded legacy documents was initially 100 MB. Individual files are limited to 10 MB.

In July 2016, DigiLocker recorded 2.013 million users with a repository of 2.413 million documents. The number of users saw a large jump of 753,000 new users in April when the central government urged municipal bodies to use DigiLocker to make their administration paperless.

From 2017, the facility was extended to allow students of the CISCE exam board to store their grades 11 and 12 academic certificates in DigiLocker and share them as required. In February 2017, Kotak Mahindra Bank started providing access to documents in DigiLocker from within its net-banking application, allowing users to electronically sign and share them. In May 2017, over 108 hospitals, including the Tata Memorial Hospital were planning to launch the use of DigiLocker for storing cancer patients' medical documents and test reports. According to a UIDAI architect, patients would be provided a number key, which they could share with other hospitals to grant them access to their test reports.

As of December 2019, DigiLocker provides access to over 372 crore (3.72 billion) authentic documents from 149 issuers. Over 3.3 crore users are registered on the platform, and 43 requester organisations accept documents from DigiLocker. In 2023, the Government of India integrated the Passport Application Form with DigiLocker. As of December 2024, the DigiLocker platform facilitated 9.4 billion document issuances to 43.49 crore (approximately 434.9 million) users.

There is also an associated facility for e-signing documents. The service is intended to minimise the use of physical documents and reduce administrative expense, while proving the authenticity of the documents, providing secure access to government-issued documents.
