About the name
What is a load letter?
Depending on who is asking, a load letter is a cryptic printer error, a piece of trucking paperwork, or the thing that lands in a freight broker's inbox every week. Here are all three, in order of how often people search for them.
1. The printer error
If you typed "what is a load letter" into Google, there is a good chance you were thinking of a printer. Specifically, the message PC LOAD LETTER on the little LCD of an HP LaserJet, which a generation of office workers stared at without any idea what it wanted.
It wanted paper. "PC" stood for paper cassette, the main tray. "LOAD LETTER" meant load Letter-size paper, the standard 8.5 by 11 inch sheet used in the United States. The printer had received a job formatted for Letter and the tray was either empty or holding a different size (A4, Legal). Load the right paper, press Continue, and it went away.
Nobody knew that, which is why the 1999 film Office Space got a laugh out of it. Michael Bolton, the character, not the singer, yells "PC load letter? What the f*** does that mean?" at the printer, and the movie's most famous scene, three employees beating the machine to death in a field with a baseball bat, is the payoff. The phrase outlived the printers. It now means any machine telling you something in a language it never bothered to teach you.
2. The freight term
In trucking and freight brokerage, "load letter" is not a formal, standardized document the way a bill of lading or a rate confirmation is. You will not find it defined in the FMCSA regulations. But people use it, loosely, to mean one of three things:
- The rate confirmation. The page a freight broker sends a carrier to confirm the rate, pickup, delivery, and terms for a load. This is the most common meaning when a dispatcher or driver says "send me the load letter." We have a full guide to what a rate confirmation must include.
- The load tender. The document or EDI message a shipper sends to a broker or carrier offering a load: what, where, when, and sometimes the contract rate.
- A pickup authorization letter. Less common: a shipper's letter on letterhead authorizing a named carrier to pick up specific freight, used at some ports, rail yards, and secure facilities.
If a shipper or carrier asks you for a load letter, the right move is to ask which one they mean. Nine times out of ten it is the rate confirmation.
3. The newsletter
The Load Letter is a free weekly email for freight brokers, written by a working broker who still quotes lanes every morning. The name is a pun on both of the above: it is a letter about loads, and it is the opposite of the printer. The printer told you something cryptic and left you to figure it out. The newsletter takes what the market did this week, explains it from a broker's desk, and ends every section with the exact thing to say to a shipper about it.
Each issue covers the three biggest moves in rates, capacity, fraud, and policy, with a "Say this" line after each one, a cold email opener for the week, and the headlines worth a click. Subscribers also get the Shipper Prospecting Kit. You can read every past issue here, browse the broker guides, or subscribe for free.
And if what you actually needed was paper in the tray, we hope that's sorted too.
What does "PC Load Letter" mean on a printer?
On older HP LaserJet printers, "PC LOAD LETTER" meant the paper cassette (PC) needed to be loaded with Letter-size paper (8.5 by 11 inches). The printer had been sent a job formatted for Letter paper and the tray was empty or held a different size. The message became famous from the 1999 film Office Space, where a character shouts "What does that mean?" at the printer before the staff destroy it in a field.
What is a load letter in trucking?
"Load letter" is not a standard term in US trucking, but people use it loosely for the documents that confirm a load: the rate confirmation a broker sends a carrier, the load tender a shipper sends, or occasionally a shipper's letter authorizing a carrier to pick up. If someone asks you for a load letter, ask which of those they mean; usually it is the rate confirmation.
