Amazon.com has placed new limits on its Amazon Prime subscription service, making it more difficult to split the service with several other people, reports TechCrunch.

Previously, account holders were able to share the $99 account with four other people. New subscribers will now face different rules. Prime membership can now be split only between two adults, who can add four children.

In order to share Prime benefits, though, these two adults must authorize each other to use their debit or credit cards on file.

The move appears aimed at reducing the ease of sharing accounts and thus spurring more people to get their own accounts.

Amazon could not be reached for comment about the new policy.
