Dear Vaibhav, you can edit your address during the correction window. Having said that, NBE doesn't communicate with Candidates through letters. All communication is online either at your Registered email id or mobile number. Neverthless, NBE will open its correction window tentatively from December 7th to December 15th. However this is a tentative window. Please keep an eye on the official website for more information. Also please visit our page if you need to know more about NEET PG 2020 at: https://medicine.careers360.com/exams/neet-pg
