Renew FSSAI Before It Expires
FSSAI registrations and licences are valid for the 1 to 5 years you paid for. Renew online on FoSCoS before the expiry date: log in, open your licence, choose renewal, pick the number of years and pay the same yearly fee.
Renewing after the expiry date costs a late fee for each day, and after a while the licence can no longer be renewed and you must apply fresh. Selling food on an expired number can get your marketplace listings blocked, so set a reminder well before the date.
