What is an Authorization Letter?

A letter of authorization, also known as an authorization letter, is a formal and legal document that authorizes a third party to act on the behalf of the individual writing the letter. Simply put, you are granting someone legal authority to act on your behalf. When you do this, you are directly accountable for the activities that occur, so always authorize someone you trust.

An authorization letter is very important in educational, business, and banking situations. If a person is unable to submit his fees and crucial documents because he is sick or absent at the moment, he might authorize a person of his trust to do so on his behalf.

Guidelines to Write an Authorization Letter?

  • An authority letter is a formal document that must be typed and neatly signed rather than handwritten in order to have more impact and serve as strong proof.
  • The letter should be written in a formal business tone. Be kind and professional while drafting a business letter.
  • Begin by writing your name and address on the left side of the page, followed by the date the letter was written.
  • Instead of being demanding, the tone should be authoritative. For example, instead of saying “Jack will execute my duties,” you say “I hereby give authorization to Jack to perform XYZ duty on my behalf.”
  • The body of the letter should be brief and to the point. Don’t go on and on about the cause for your absence. Give your case in no more than 3-4 lines. Also, avoid becoming too personal.
  • Mention a call to action. In case something goes wrong, always provide your contact information in the note. Remember that even after distributing responsibilities, you are still liable.

Format for an Authorization Letter

The method and format for writing an authorization letter are the same as for any other letter. Furthermore, the letter of authorization should include precise information about the individual who needs to be approved as well as instructions on how to send the documents to the appropriate person.


Recipient’s Full Name

Recipient’s Address




Body of the letter: Declare what is being authorized and to whom the authorization is being granted. Provide specifics to reassure the reader that the letter was written by you. For greater clarity, specify statistics and numbers.

Also, define the tasks that the individual will be performing on your behalf. This is done to prevent the agent from abusing their authority and doing more or less than what they were authorized to do.
