What is a rate confirmation?

A rate confirmation — universally called a "rate con" in freight — is the per-load contract between a freight broker and a carrier. It is the document that turns a verbal or email negotiation into a binding legal agreement. Every load that moves through a brokerage should have a signed rate confirmation on file. Understanding what belongs in one — and what omissions create liability — is foundational knowledge for any freight broker.

What a rate confirmation is (and what it is not)

A rate confirmation is a load-specific document issued by the broker to the carrier after a rate has been agreed. It confirms the terms for that specific shipment: where the truck is going, when, at what rate, and under what accessorial conditions.

A rate confirmation is not the same as:

• A broker-carrier agreement (BCA): The BCA is the master agreement governing the ongoing relationship between a broker and a carrier. It covers liability, cargo claim procedures, compliance requirements, indemnification, and general payment terms. The rate con references and incorporates the BCA for each individual load. Carriers sign one BCA with a broker; they sign individual rate cons per load.
• A bill of lading (BOL): The BOL is the contract of carriage between the shipper and the carrier. It is the document that accompanies the freight and records the condition of the cargo at pickup. The broker typically does not appear on the BOL as a party — the carrier is listed as the transporting carrier.
• A load tender: A load tender is the shipper's offer to the broker to move a load. The rate confirmation flows downstream — broker to carrier — after the broker has accepted the shipper's tender and sourced capacity.

Required fields in a rate confirmation

There is no federal mandate specifying what a rate confirmation must contain, but industry standard and practical dispute-avoidance require these fields at minimum:

Load identification

• Load or reference number: The broker's internal load ID. This is the number the carrier should reference in all communications and invoices.
• Date issued.

Parties

• Broker name, address, and MC number.
• Carrier name, address, and MC number.
• Driver name and contact number (often added at dispatch after the carrier assigns a driver).
• Truck and trailer number (also typically added at dispatch).

Load details

• Origin: Shipper name, street address, city, state, ZIP, contact name, phone, and appointment date/time (or FCFS — First Come, First Served — notation if no appointment).
• Destination: Consignee name, address, delivery appointment date/time.
• Commodity: Description of the freight. Important for insurance and cargo claim purposes.
• Weight (in pounds).
• Equipment type: Dry van, reefer, flatbed, step-deck, etc. Including trailer length (48' or 53') if applicable.
• Temperature range (for reefer loads).

Rate and payment terms

• Agreed linehaul rate in dollars.
• Fuel surcharge (if separate from the all-in rate).
• Accessorials pre-authorized: Detention rate and free time, TONU amount, stop-off charges, lumper authorization, layover rate. Any accessorial not listed is likely to become a dispute.
• Payment terms: Standard pay (e.g., net 30 after receipt of invoice and POD) or quick pay percentage and timeline.
• Invoicing instructions: Where to send the invoice and required supporting documents (POD, signed BOL).

Reference to broker-carrier agreement

The rate con should include a line stating that the carrier acknowledges and agrees to the terms of the broker-carrier agreement already on file, and that the BCA is incorporated by reference. This is the legal mechanism connecting the load-specific rate con to the master agreement terms on liability and cargo claims.

Signature block

Both broker and carrier should sign and date. For electronic signatures (DocuSign, HelloSign, or email confirmation), retain a clear audit trail. An email from the carrier confirming the load terms constitutes acceptance in most jurisdictions, but a signed document is always stronger evidence in a dispute.

Legal status: is a rate confirmation binding?

Yes, once signed by both parties, a rate confirmation is a binding contract. It creates enforceable obligations on both sides: the carrier is obligated to pick up and deliver the load as specified, and the broker is obligated to pay the agreed rate upon delivery and receipt of required documentation.

Courts have generally treated signed rate confirmations as binding agreements even when the parties later dispute whether the BCA terms also apply. The rate con's incorporation-by-reference language typically controls whether the BCA terms travel with the load-level agreement.

Practical implication: do not issue a rate confirmation with vague accessorial language expecting to sort it out later. Whatever is written on the rate con is the contract. Disputes about detention, lumpers, and fuel surcharges are the most common payment conflicts in freight brokerage — and most of them could be prevented by explicit rate confirmation terms.

Common rate confirmation scams

The rate confirmation is a vector for several freight fraud schemes that brokers need to be aware of.

Identity theft / impersonation

A fraudulent actor impersonates a legitimate carrier (using a real MC number that does not belong to them) to sign a rate confirmation, gain access to the shipper's facility address and load details, and either steal the cargo or re-tender the load to a second carrier without the broker's knowledge. Verifying that the entity signing the rate con actually controls the MC number they are presenting — not just that the MC number is Active — is critical. This is identity verification beyond FMCSA status checking, and is the area where platforms like Highway add value beyond the free FMCSA tools.

Rate con alteration

After signing, a bad-actor carrier sends a modified rate confirmation for payment — with an inflated rate, added accessorials, or altered payment terms. Brokers should retain original signed copies and compare them against any carrier-submitted documents. TMS platforms that store signed rate cons automatically provide the strongest protection against this.

Double brokering via rate con acceptance

A carrier signs the rate confirmation, receives the shipper's pickup information, and then re-tenders the load to a second carrier without the original broker's knowledge. The original broker has no relationship with the actual truck moving the freight, creating liability exposure and loss of visibility. See our guide on what is double brokering and how to prevent double brokering.

Rate confirmation and the carrier selection workflow

In the brokerage workflow, the rate confirmation comes after — not before — carrier selection. A broker receives 30–50 carrier emails per posted load, triages them to find the best rate from a verified carrier, selects a carrier, negotiates final terms, then issues the rate confirmation.

The triage step is where most brokerages spend the most time and where the most risk enters the process — booking a carrier whose MC is revoked, whose authority age is suspiciously new, or whose email domain does not match their FMCSA record. Keelway's carrier email automation handles the triage step, parsing inbound emails and surfacing a ranked list of verified carriers with trust scores already computed. The broker selects from the ranked list and issues the rate confirmation with confidence.
