New basic free accounts registered from November 13, 2013 onward can now connect a maximum of five Twitter accounts to their user account. Previously there was no cap to the number of Twitter accounts that could be connected to a free user account. To add more than five Twitter accounts the user account must now be upgraded to the Twitter Unlimited level or to the Professional level.

User accounts registered before November 13, 2013 were grand-fathered in, meaning they can still connect an unlimited number of Twitter accounts at the basic free level.
