Market regulator Securities and Exchange Board of India on Thursday exempted residents of Sikkim from the requirement of mandatory quoting of PAN for investing in mutual funds.

However, an investor will have to provide the documentary proof of being a resident of Sikkim, the regulator said in a circular.

"It has been decided to exempt investors residing in the state of Sikkim from the mandatory requirement of PAN for their investments in mutual funds," the regulator said.

SEBI had earlier exempted Sikkim residents from providing their PAN for opening accounts with depositories and trading in the cash market.
