The Food Safety and Standards Authority of India (FSSAI) mandates a Class 3 Digital Signature Certificate in the Food Business Operator's (FBO) name for any submission on the FoSCoS portal — fresh licences, renewals, modifications, and annual returns. The portal is notoriously fussy about signature validation, and errors tend to be cryptic ("Digital Signature Verification Failed") without any indication of what went wrong. We've resolved most of the common failure modes and can usually fix a bounced FSSAI submission inside a session.
- Class 3 DSC issued in the FBO's exact registered name (matching FoSCoS records)
- Portal registration and signature-verification troubleshooting included
- Works for FSSAI Central, State and Registration category licences
- Same DSC also works for GST, MCA, Income Tax filings
- Renewal reminders so your food licence never lapses on a signature expiry
- Restaurants, cafés, bakeries, cloud kitchens and QSR operators
- Food manufacturers, processors, packers and repackers
- Wholesalers, distributors and importers of food products
- Caterers, transporters, and e-commerce food sellers

How it works
- 01
FBO name reconciliation
We verify the DSC will be issued in the exact name FoSCoS holds on record — a mismatch is the single most common cause of signature rejection.
- 02
Class 3 DSC issuance
Aadhaar e-KYC + video verification and issuance on a FIPS-compliant USB token.
- 03
FoSCoS DSC registration
We register the DSC against your FoSCoS user ID and validate signature verification on a sample submission.
- 04
First-filing support
For fresh licence applications, we handhold the FoSCoS submission on a screenshare to avoid rejection.
1 hour for DSC issuance. FSSAI licence itself takes 7–60 days depending on category and licensing authority.
Our "DSC in 1 hour" claim covers a Class 3 Individual DSC for Indian citizens who walk into our Nagavara office between 10 AM and 3 PM (Mon–Sat) with a valid PAN, an Aadhaar linked to an active mobile number, and are able to complete the Certifying Authority's video verification on the spot. It assumes CCA and Aadhaar UIDAI systems are up and OTPs are received on the first attempt.
- •Organisation, DGFT, ICEGATE, FSSAI and Foreign/NRI DSCs need extra verification and typically take longer — see the timeline above.
- •Doorstep pickup, courier delivery, or after-hours requests add ~4 hours on top of the 1-hour issuance window.
- •Portal outages at the CCA, UIDAI or Certifying Authority are outside our control and can extend timelines.
