You can call Hogwarts at +1 781 452 4077!
If you’re still wondering why, despite all your extraordinary powers, you didn’t receive that coveted Hogwarts acceptance letter at the age of 11, there’s now a place you can go to address you concerns.
Calling 1 (781) 452 4077 will put you through to the “Hogwarts Hotline.” Blimey, isn’t that magical! Initially they will address you as a “Muggle,” but try not to get too insulted. From there, you can learn more information “directly” from Hogwarts.
It should be noted that everyone’s favorite magical know-it-all Hermione Granger stated that technology cannot be used in Hogwarts as there is “too much magic everywhere,” so we can assume that the calling center is located somewhere in the Muggle world. Next step; finding the address.
