What is Nadakacheri (AJSK) in Karnataka?

Nadakacheri is the online portal of the Karnataka Revenue Department, run under the Atalji Janasnehi Kendra (AJSK) project. It was launched in 2012 and the current version is Nadakacheri 5.0. The official website is nadakacheri.karnataka.gov.in .

Through Nadakacheri, citizens of Karnataka can apply for more than 40 government services online, without standing in long queues or visiting many offices. The most popular services are:

• Caste Certificate (proof of caste for reservation and category benefits)
• Income Certificate (proof of annual family income for scholarships, loans, and benefits)
• Residence / Domicile Certificate
• OBC, EWS, Minority Certificates
• Agriculture, Pension, and Disability Certificates

You can use the portal in Kannada or English. It provides OTP-based login, SMS notifications for application updates, and a digitally signed certificate that can be downloaded and printed.

Caste Certificate vs Income Certificate: Two Separate Applications

Many people get confused because both certificates are on the same Nadakacheri portal. But:

• The caste certificate and the income certificate must be applied for separately.
• You will receive a different RD number for each certificate.
• Each application is checked and approved separately by the revenue department officials.
• You can apply for both on the same day, but you must fill two separate forms and pay the service fee for each.

So do not expect one application to give you both certificates. Treat them as two different requests, each with its own RD number for tracking.

Documents Required for Nadakacheri Caste Certificate

Before you apply for a Nadakacheri caste certificate, keep these documents ready:

• Aadhaar Card of the applicant
• Ration Card (for family details)
• Proof of caste — such as the parent’s caste certificate, or school records (SSLC/TC) showing the caste
• Residence proof (address proof of Karnataka)
• Passport-size photo
• Active mobile number (for OTP and SMS updates)

Make sure your caste details match across your documents and school records. A mismatch is a common reason for rejection.

Documents Required for Income Certificate (Nadakacheri)

For an income certificate, the documents focus on proving your family’s income. Keep these ready:

• Aadhaar Card of the applicant
• Ration Card
• Income proof — such as a salary slip / employer certificate (for salaried families), or a self-declaration of income (for daily-wage or farming families)
• Land records (if applicable, for farming families)
• Residence proof
• Passport-size photo and an active mobile number

Nadakacheri Fees and Processing Time

Many people ask about the cost and how long it takes. Here is the simple answer:

• Service fee: A small fee is charged for each certificate application (paid online).
• Reprint fee: If you need a duplicate copy later, the reprint fee is ₹40 per certificate (usually paid through SBI e-Pay using UPI or card).
• Processing time: Normally 7 to 21 working days. In some cases, if you upload all correct documents, the certificate can be approved within 24 to 48 hours.

The exact time depends on how quickly the Village Accountant verifies your details and the Tahsildar approves them.

Nadakacheri Verification and Approval Process

After you submit your application, it goes through a step-by-step verification before the certificate is issued:

1. The Village Accountant (VA) checks and verifies your details and documents.
2. The application moves up for further checking by the revenue officials.
3. The Tahsildar or Deputy Tahsildar does the final approval and e-signs the certificate.
4. Once approved, you get a final SMS with a download link for your certificate.

You will receive an SMS at each stage on your registered mobile number, so you always know where your application stands.

How to Check Nadakacheri Application Status Online

After applying, you can easily track your status. There are two methods:

Method 1: Check Status by RD Number

1. Visit the status page at ajsk.karnataka.gov.in/NK_Status and choose your language.
2. Select the “Acknowledgment No” option and enter your RD number (printed on your slip and sent by SMS).
3. Fill the captcha and click “Check Status” to see your current status.

Method 2: Check Status by Mobile Number

If you do not have the RD number, visit the same status page, choose the mobile number option, and enter your registered mobile number to view your application status.

Nadakacheri Status Meanings and Rejection Reasons

When you check your status, you may see different results. Here is what they mean and how to fix common problems:

• Pending / Under Verification: Your documents are being checked by the Village Accountant or revenue officer. Just wait.
• Approved: Your certificate is ready to download.
• Rejected: Check the “Remarks” column for the exact reason and reapply with corrections.
• “No record found”: You entered the wrong RD number. Recheck and try again.

Common reasons for rejection include: no supporting proof for the caste or income claim, an inactive mobile number (officer could not verify), duplicate applications, or incorrect details / address or caste mismatch. Fix the issue and reapply with clear, correct documents.

How to Download or Print Nadakacheri Certificate

Once your certificate is approved, you can download it instantly:

1. Go to the “Print Certificate” section on the Nadakacheri portal.
2. Enter your RD number and submit.
3. Download or print your digitally signed certificate.

Disable the pop-up blocker in your browser before clicking Print, and a desktop or laptop is easier than mobile. The downloaded PDF is digitally signed and legally valid across Karnataka.

How to Reprint a Lost Nadakacheri Certificate

If you lose your certificate or need an extra copy, you can reprint it easily:

1. Go to the “Reprint” option under the Print menu.
2. Enter your RD number.
3. Pay the ₹40 reprint fee (through SBI e-Pay / UPI / card).
4. Download your duplicate certificate.

Note: “Print” is for the first copy after approval, while “Reprint” is for additional copies. If the print button does not appear after payment, use the “Reprint (Print Failed)” option and re-enter your RD number.

How to Verify a Nadakacheri Certificate (CV)

Schools, colleges, employers, and government offices often need to verify a certificate’s authenticity. Karnataka has a Certificate Verification (CV) system for this:

1. Visit the verification page at ajsk.karnataka.gov.in/nkcv/.
2. Enter the certificate’s RD number.
3. The system will confirm whether the certificate is genuine and valid.

Only certificates issued through the Nadakacheri (AJSK) portal can be verified online. This helps prevent the misuse of fake or expired certificates.

Why the RD Number is So Important

The RD number (Revenue Department number) is the heart of the whole process, so keep it safe. You need it to:

• Track your application status.
• Download or reprint your certificate.
• Verify the certificate’s authenticity.
• Fill scholarship applications like the SSP and Vidyasiri scholarships, which ask for your caste certificate RD number and income certificate RD number.

Because the RD number can let others access your certificate, keep it private and do not share it on unknown websites.

Validity and Renewal of Nadakacheri Caste Certificate and Income Certificates

It is important to know how long your certificates last:

• Caste certificate: Usually has a long validity, but it may need renewal after a set period depending on the type and the purpose.
• Income certificate: Generally valid for a limited time (often about one year), after which it must be renewed.

If your certificate has expired, simply apply again on the Nadakacheri portal to get a fresh one. Always check the validity before submitting it for scholarships or job applications.

Nadakacheri Helpline and Support

If you face any problem while applying, checking status, downloading, or verifying, you can get help:

• Email Helpdesk: helpdeskajsk@gmail.com
• In Person: Visit your nearest Nadakacheri / Atalji Janasnehi Kendra (Taluk office) with your RD number and original documents.

For long delays, note your “Action Taken On” date on the status page and visit the district or taluk office with your application number.

Apply on nadakacheri.karnataka.gov.in, upload correct documents, pay the small fee, and track your status using your RD number.

Certificates are usually issued in 7 to 21 days, are digitally signed and valid, and can be downloaded, reprinted (₹40), or verified anytime.

For any issue, the helpdesk email and your local Nadakacheri office are there to help.
