To make phone calls
- "Mrs. Weasley had braved the telephone in the village post office to order three ordinary Muggle taxis to take them into London."
- —-Harry Potter and the Goblet of Fire
A telephone is a Muggle device used to communicate long distances, and is powered by electricity. Wizards, such as Ron Weasley, underestimate their abilities, feeling the need to shout into the phone to be heard. The wizarding world equivalent is owl post and the Floo Network. Arthur Weasley frequently referred to the telephone as a "fellytone." On 1 November 1981, Vernon Dursley made "several important phone calls" while at Grunnings and later nearly dialed his home number after becoming panicked about the strange activity around him, but thought better of it. Later that day, Jim McGuffin reported on the television news that viewers had phoned him about downpours of shooting stars, rather than promised rain. In 1991, when Harry Potter observed Rubeus Hagrid using owl post to send a letter to Albus Dumbledore, he thought that Hagrid sat down as though what he had done was as normal as talking on the telphone. In 1993, Ronald Weasley attempted a telephone call to Harry Potter, but it went poorly because he shouted into the receiver and mentioned Hogwarts School of Witchcraft and Wizardry after Vernon Dursley took the call. Molly Weasley "braved" using a telephone in 1994 to get 3 taxis to escort the Weasley family, Harry Potter and Hermione Granger to King's Cross Station in London to board the Hogwarts Express.
A telephone booth is used as the visitor's entrance to the British Ministry of Magic. Dialing 62442 (telephone number code for "magic") allows one to make a connection, allowing them to state their business, receive a badge, and then transport down into the Ministry.
Behind the scenes
- On the main page of the J. K. Rowling Official Site in the upper right corner was a mobile telephone, prior to the site's April 2012 redesign Punching in 62442 on the phone's keypad (the same combination used to access the visitor's entrance of the Ministry of Magic, and telephone code for "Magic") caused a brief voice clip of J. K. Rowling answering the phone to play.
