In the news

The National Single Window System: what happened?

A new factory may need dozens of permits from the Centre, the State and regulators. Earlier, an investor ran from office to office and filled the same details again and again. NSWS puts these approvals behind one login. PIB marked its fifth year with a backgrounder.

  • NSWS completed 5 years on 22 September 2026.
  • It hosts approvals from 32 Central Ministries/Departments and 34 States and UTs.
  • It receives over 3.06 lakh applications and helps process over 2.26 lakh approvals each year.
  • PESO has put all 74 of its licensing modules on NSWS, the first department to integrate fully at transaction level.

Fault Lines

What are the challenges in the National Single Window System?

  • Integration is still uneven: Assam has 335 approvals on NSWS, Manipur 190, and many States fewer.
  • NSWS forwards files; the actual decision still sits with each Ministry or State, so delays there remain.
  • KYA guidance is advisory only, so investors may still need legal help.
  • Only PESO has full transaction-level integration so far.
Road Ahead

What should be done next on the National Single Window System?

  • Bring every Central and State approval onto NSWS at transaction level, as PESO has done.
  • Set and publish time limits for each approval.
  • Merge more State Single Window Systems with the national portal.
