How to Write an Authorization Letter?

An authorization letter is a formal letter, and so it follows a format that is mostly similar to the format of a formal letter. An authorization letter is usually handed over in person, so you can start the letter with the receiver’s name and address. Mention the date on which the letter is written. The subject line denotes the purpose of the letter. This is followed by the salutation or greeting and then the body of the letter. Make sure you mention the name of the person you are authorizing and the action to be performed clearly. Once you do this, see to that you thank the person for understanding your situation and acknowledging your request. Use a complimentary closing to finish the letter.
