What is a Class III DSC for Business?

A Class III DSC (Digital Signature Certificate) is a digital version of your signature that you use online to sign important documents. It is the most secure type of digital signature, made especially for businesses, professionals, or individuals who need to do official work online, like filing GST, submitting tenders, signing income tax returns, or uploading documents on government portals like the MCA (Ministry of Corporate Affairs).

In simple words, if your business needs to bid in eTenders, file forms for your company, submit GST returns, or do other official work online, then you will need a Class III DSC. It works like your digital identity, and it's completely legal and safe to use.

CallMyCA helps you get your DSC without going anywhere – all you need is your phone, some basic documents, and 10 minutes. You just upload your documents, do a short video verification, and we handle the rest. It’s fast, easy, and fully online.
