What Is an Authorization Letter?

Updated: 2025-10-05

An authorization letter is a formal document that grants someone permission to act on your behalf for a specific task or time period. It serves as written proof of consent and clearly defines boundaries so organizations can verify identity and prevent misuse. A well-written authorization letter states who is authorized, what they may do, and when the authority begins and ends. This clarity helps banks, schools, clinics, and government offices process requests efficiently and safely.

What It’s Used For

  • Administrative tasks: Picking up documents, packages, or records.
  • Financial matters: Bank transactions or account inquiries.
  • Legal processes: Representation in limited, defined contexts.

A clear authorization letter specifies the authorized person, scope, time frame, and any limitations. Include identification details if required and keep a copy for your records to ensure smooth processing. Reviewing trusted samples and templates can help you follow best practices.
