Owl Postal Service

Owl post is a wizarding system of sending messages or items using owls as the carriers. Besides the Owl Post Office, individuals and organisations with their own owls use them as their mail bearers — owls are employed by wizards in such numbers that is estimated that virtually all of them are either the property of the Postal Service or individual wizards.^[1] Harry Potter's owl, Hedwig, was used as his primary means of communicating with his friends and his godfather, Sirius Black. Hogwarts School of Witchcraft and Wizardry had a number of owls that anyone at the school could use. They, along with students' personal owls, were kept in the Owlery.

History

Hogwarts use

At Hogwarts, owls live in the Owlery in the West Tower and deliver mail to students once a day, at breakfast – though more urgent messages are frequently delivered to Harry in his dormitory.

Hogwarts also has a number of school owls, which can be used by students who do not own an owl themselves. Harry used school owls on several occasions when he needed to contact Sirius without attracting attention. These owls seem to be used on occasion even to communicate across the school, such as when Hagrid sends a note to Harry at the end of his first week at Hogwarts, though this method seems to be given up by Harry’s sixth year, when notes are instead regularly delivered in the hands of students.

Beginning in Harry’s fifth year, all owl post into Hogwarts was searched and inspected as a security precaution. This was originally seen as an overbearing method of control by the Ministry of Magic and Dolores Umbridge, but once Voldemort’s return became public it was widely accepted. Intercepting owls can be done crudely or routinely. Hedwig was hurt when Umbridge intercepts her letter, but the Weasleys’ mail and Hogwarts mail is later searched as a matter of routine, with no harm coming to the animals.

Business use

Owls are also used for institutional deliveries, the first time we see an owl making a delivery is when one arrives with Hagrid’s Daily Prophet in the hut-on-the-rock. In this case, the owl has a pouch which it uses to collect Hagrid’s money.^[2] Later, though, Hermione takes out a subscription to the Daily Prophet as well, and the owls that deliver it don’t seem to collect anything.

Owls are also used by some businesses for Owl Order Service, to deliver goods. This service comes into prominent use, when a Slug Club Christmas party is approaching his sixth year, and girls buy love potions from Weasleys’ Wizard Wheezes through Fred and George’s Owl Order Service. Fred Weasley and George Weasley conducted much of their business for Weasley's Wizard Wheezes via an owl order service.

In 1995, the British Ministry of Magic enacted several laws regarding censorship of owl post.

Use of owls

Post owls are quite intelligent, and can usually find their mail's recipient with little to no direction.

Other birds can be used for delivering messages. Sirius Black, while in hiding, sent unspecified tropical birds as message carriers while communicating with Harry Potter. This lead Harry to speculate that Sirius was hiding in a warmer environment than England. However, the preponderant bird used for messaging was the owl. Muggles have their own form of post and therefore do not use owls, nor were they generally aware that owls or other birds could be used for correspondence.

Some magic is used by owls in finding their recipients; Hedwig, for example, is able to easily locate Sirius Black when he is on the run from the Ministry of Magic, even though Aurors are unable to do so.^[3] Hedwig also routinely hunts Harry down in Hogwarts, in Gryffindor Tower or even his classes^[4], and Pigwidgeon successfully delivers a letter to Harry while he is on the moving Hogwarts Express.^[5] However, wizards cannot send an owl to someone they want to find and then “follow” the owl to discover the person’s whereabouts.

Behind the scenes

• It is possible to make oneself impossible to be traced by owl post; Sirius Black and Lord Voldemort both were able to do so to avoid having the British Ministry of Magic find them^[23]
• According to W.O.M.B.A.T., it may be illegal to send mail-bearing owls across international borders without authorisation.
• The non-canonical Educational Decree Number Forty-Seven required Hogwarts students to submit to their post being searched for illegal contraband. In the Harry Potter and the Order of the Phoenix novel, Dolores Umbridge had her Inquisitorial Squad examine the post of all incoming owls, apparently regardless of student consent.
