Guidelines for Seeding and Authentication services


  1. Seeding: Aadhaar seeding is the process by which the UIDs of consenting residents are accurately included into the service delivery database of the service providers for Aadhaar-enabled service delivery. Aadhaar seeding is a pre-requisite for Aadhaar-enabled service delivery.

Why Seeding?

  • Seeding enable residents to easily establish their identity and claim their benefits / obtain services
  • Minimizes the hassle of repeated verification of the residents

How to Seed?

The seeding process involves 3 major steps. The details are provided as a flow chart for your easy reference.

  • Step1: Capture of Aadhaar

This process is termed as mapping. The department is required to gather Aadhaar details and update the beneficiary records with respective Aadhaar. Aadhaar details may be collected using different channels. At a broader level the departments are classified as follows:

  1. Departments that are e-enabled
  2. Departments in the process/ yet to be e-enabled

  1. Departments that are e-enabled: Departments having maturity in using software applications towards the activities of the department like beneficiary identification/selection, registering the beneficiary, benefit transfer etc.
    • Departments Application: The following set of activities are suggested:
      • Department to make a provision to capture the Aadhaar number in software application.
      • The departments should ensure to capture the Aadhaar number along with the Consent of the Aadhaar holder as is the requirement of UIDAI.

        Best Practice:
  • Bar code scanner to capture the bar code on the Aadhaar. This will avoid the typo errors.
  • Usage of Vehoeff algorithm to verify validity of Aadhaar. Aadhaar number does not start with “0” or “1”. The last digit in the Aadhaar is a checksum. The Verhoeff algorithm validates the Aadhaar number with these checks. CeG will share the algorithm with the departments. This validation will minimize capture of wrong Aadhaar thereby saving time and effort.
  • It is recommended to capture the name exactly as in Aadhaar.
    • Self-service portal: KRDHwill provide an application module that will facilitate capture of Aadhaar. The departments will have to integrate this module in their software application.This module will facilitate for the capture of
      • Aadhaar of the beneficiary
      • Consent of the Aadhaar holder
      • Department and Bene ID

And also to validate and generate/push data to department database.

  1. Departments in the process/ yet to be e-enabled: Departments that are currently not making use of any software application to capture and maintain the beneficiary data. The departments make use of one of the following channels for assistance in capturing the Aadhaar mapped beneficiary data.
    • Physical forms: The most basic form of data gathering is through the physical forms. Various channels in which the physical forms may be captured are as described below:
      • Document collection: Department may deploy seeding operators at various resident touch points like the ration shops, B1/K1 centres, AJSK, Gram Panchayats etc. The resident may hand over the copies of Aadhaar, physical consent form along with the details of the beneficiary ID.

        Best Practice:
        • The photocopy of Aadhaar is also to be collected and maintained for future reference
      • Drop Boxes: The Department may arrange for certain colored boxes to be placed at various resident touch points like the ration shops, B1/K1 centres, AJSK, Gram Panchayats etc. The residents drop the copies of Aadhaar, physical consent form, along with the required beneficiary data.

        Best Practice:
        • The photocopy of Aadhaar is also to be collected and maintained for future reference
        • The photocopy of the beneficiary scheme allotment letter is also to be collected and maintained
      • Special Camps: The department may also conduct camps in the target location to collect seeding requests. However, this needs strong IEC, that is, awareness campaigns to mobilize the target groups to submit seeding requests. The departments may avail the assistance of the District Coordinators of CeG towards the IEC and awareness activities.

        Best Practice:
        • To facilitate camp mode of enrolments/update/corrections by the department. The District Coordinators of CeG shall provide the necessary assistance to the departments.
      • Post/ Courier: The resident may send the documents (Aadhaar, physical consent form, along with the required beneficiary data) through post or courier.
      • Door-to-Door Campaigns: The department may organize door-to-door campaigns to collect seeding requests.
    • Step2: Digitization and/ or De-duplication

      The data captured through physical forms at Step 1 is to be digitized by the department. The departments may digitize the data with the help of data entry operators.Digitization of the Aadhaar mapped beneficiary data is a pre-requisite to perform the de-duplication. 

      Post gathering the Aadhaar data through different mechanisms the department is required to perform the de-duplication process within the database of the departments. One Aadhaar being mapped to multiple beneficiaries are termed as duplicates. De-duplication is the process of identifying and eliminating such duplicates. De-duplication process ensures that multiple benefits are not availed by the beneficiary, as per the policy requirements of the department. Digitization and de-duplication process ensures
    • De-duplication of beneficiary data and
    • Elimination of ghost and duplicate entries

    • Step3: Validation of Aadhaar
      The process of verification is to ensure that only a valid and specified Aadhaar gets linked with the beneficiary ID. The departments will have to become AUA/KUA to avail the Aadhaar based authentication services. CeG will assist the departments to on-board as an AUA/ KUA with UIDAI. 

      The verificationcan be performed using application/services provided by UIDAI, the details of which are elaborated below:
  • Demo Authentication: The Aadhaar mapped beneficiary data which is digitized and de-duplicated from the previous step may first be subject to Demo Authentication. The department may become the AUA/KUA andavail the ASA/KSA services of CeG to route the Demo Auth requests to UIDAI.

    The Demo Auth response “Yes” may be seeded. In cases where the Demo Auth response “No” OTP/ Biometric authentication maybe performed.
  • OTP/ Biometric Authentication: The OTP/ Biometric authentication requires the presence of the Aadhaar holder as the OTP is generated at the registered mobile number and/or the biometrics of the individual are to be captured. The successful authentication requests may be seeded. The unsuccessful responses may be rejected. The department may become the AUA/KUA andavail the ASA/KSA services of CeG to route the Authentication requests to UIDAI

    • Step4: Link
      The final step of the seeding process is linking. Once verified, Aadhaar may be seeded in the beneficiary database
