Karnataka runs two major portals: Seva Sindhu and Nadakacheri. Between them you can apply for caste/income certificates, driving licenses, and social security pensions. If you need in-person help, look for Bangalore One, Karnataka One, or Grama One centres, plus CSCs. Before applying, make sure your Aadhaar phone link is working since e-KYC is required for nearly everything. PAN card, ration card, and bank passbook should be handy too.
