It has been confirmed that the codes for Heatran and Regigigas for the March part of the Legendary event is to be sent through the Pokémon Trainer Club(PTC) newsletter in North America via Serial Code (you need to sign up by March 1st), and Nintendo Network in Europe from March 1st to March 24th. Like Dialga & Palkia, they differ between games with Ultra Sun/Ultra Moon's being Level 100 with a Gold Bottle Cap and Sun & Moon's being Level 60. Sun & Ultra Sun get Regigigas while Moon & Ultra Moon get Heatran. Our Event Database has been updated with full details of these events

For NA, the codes would be distributed via newsletter, make sure to sign up before March 1 to get a code Source
While for PAL, it would be distributed through Nintendo Network, which means it’s going to be a WiFi event, so no codes. Event Period would be from March 1 to March 24. Source
美版將會在PTC 登記的三月通訊裏提供( 我也不太知道怎派)
歐版將會 WIFI 配信
