Any company whether listed or unlisted can opt for dematerialisation of its shares by submitting an application to the Depository and by submitting the necessary documents as provided therein and by entering in to a tripartite agreement with NSDL or CDSL. The Company has to appoint an R & T Agent for this purpose.
NSDL & CSDL both of them permit the unlisted listed companies to go for dematerialisation.
If it is a listed company it is compulsory to get it registered with both NSDL and CDSL otherwise agreement with any one depository is sufficient
