What is a letter of authorization for a dispatcher, and do I need one?

It is a short document where the carrier tells brokers and others that you may talk to them and book loads on its behalf. It is not a payment authorization. Many brokers ask for one, so it is common, but it does not replace the written agreement.

Think of the agreement as the contract between you and the carrier, and the authorization letter as the proof you show a broker so they know whose agent you are.

Keep it narrow: name what you may do (search, negotiate, book, send paperwork) and what you may not (sign freight contracts, receive payments). Check the wording with a lawyer.

Example. "Carrier authorizes Dispatcher to search for and book loads for Carrier's truck and to send routine paperwork. Dispatcher is not authorized to receive payment for any load."

General information, not legal advice. Rules change. Check the sources and talk to a transportation lawyer before you sign or start.
