How you know that you are blacklisted by any bank in India?

Answer 1

Banks etc are in the business of providing services. There is a separate industry used by banks and other business regarding the credit worthiness/history of individual customers. This industry is called a Credit Rating Service and the companies providing this service (all round the world) gather history relating to the debt load, payment history, Court judgements, bankruptcy etc. of individuals.

Banks and other business dealing with individuals will then purchase information about individuals from these Credit Rating agencies before doing business with any individual.

Therefore if business will not deal with you, it is not because THEY are blacklisting you, it is because your credit history (held by the Credit Rating Service companies) is bad.

In most countries you have a rite to ask for and see your credit history (from these companies) and to challenge and change any FACTUAL mistakes.

To help you I include a link below to a UK Credit rating company, look for a similar service in your home country.
