Heroku-Mandrill Addon: mandrill starter add on for heroku installation failed

Question

I ran the following command

heroku addons:add mandrill:starter

I ran this command on my terminal as I read it in Mandrill by Mailchimp in Heroku Learning section. It says that mandrill stater is free but when I run this command on my terminal it says:

1. Please verify your account to install this add on plan.

2. For more information visit the billing page.

Do heroku have stopped the free service or there is something which I am missing?

                                 **OR** 

Is it like I must be having a premium account on heroku to even install this free addon?

Heroku requires you to verify your account to use add-ons. See their help center article for more details and reasoning: https://devcenter.heroku.com/articles/account-verification
