Get Fide-rated without revealing your birthday? I noticed the Fide rating list is always published with the date of birth of the player. Is registering one's actual birthdate with Fide a requirement for a Fide rating? It is a major concern for me given the rise in cases of identity theft.
Yes it is.

Article 1.14 in Regulations for Registration &amp; Licensing of Players (effective from July 1, 2015):


  All player's data are obligatory for online registration in FOA. For players registered by the National Rating Officers or the FIDE Rating Administrator, first name, last name, gender, date of birth, e-mail address and Federation are obligatory for a successful registration.
