National Single Window System

The National Single Window System (NSWS) is a digital platform implemented by the Department for Promotion of Industry and Internal Trade (DPIIT) to guide investors in identifying and applying for business approvals. Launched on September 22, 2021, and completing five years of operation, the portal integrates approvals across Central Ministries, State Governments, and regulatory bodies through a single interface. Key functionalities include the Know Your Approvals (KYA) module, a Common Registration Form, an Applicant Dashboard, a centralized Document Repository, and an E-Communication Module. By streamlining submissions, reducing duplication, and utilizing the Permanent Account Number (PAN) as a single business ID, NSWS supports the ease of doing business and fosters a transparent investment ecosystem in India.
