Dear Prapa

The nodal centres are the places where document verification is done. Each state has their own method/mode for verification of documents for e.g. nodal centres for U.P. NEET COUNSELLING 2019 is listed in their official website under the 'notification' headline NEET_UG_2019_POLICY_DATED_17_06_2019 and no there may not be messages or emails sent by state counselling authority.

For more detailed info. kindly provide specific state in which you are willing to apply.

Hope this helps you.
