The Information Technology (IT) Ministry has proposed that significant social media companies should maintain a database of active mobile numbers of all their users for verification purpose under a revised set of rules, according to a source.

The proposal, aimed at tackling issues related to anonymity of users in the fast-growing social media space, has been mooted for the first time as part of the amendments likely to be made to the existing IT intermediary rules, the source said.

Social media companies with more than fifty lakh users in India will be categorised as significant social media intermediaries. These companies will also have to comply with stricter obligations, including traceability of users, under the revised rules, the source said.

The ministry has sent a draft of the revised rules to the law ministry for vetting.
