JK Rowling Addresses If you want to write JK Rowling a letter, the addresses are listed below. As of now, Miss Rowling does not have an email address (based on some of her Chat Transcripts, I think she might be afraid of the Internet!), and so I don't have any electronic way of contacting her. I guess you'll have to use "snail mail". US Address: JK ROWLING c/o Scholastic Books 555 Broadway New York, NY 10012 UK Address: JK ROWLING c/o Bloomsbury 38 Soho Square London W1V 5DF UK MainJK Rowling page.
