O TruckingWhat is a Comcheck?
In This Guide
How Comchecks Work
A Comcheck is essentially a secure money transfer system designed specifically for the trucking industry. Created by Comdata Corporation (now part of Fleetcor) and trademarked since 1974, it's been the industry standard for over-the-road payments for five decades.
Here's how the process works:
Broker/Carrier Sets Up Comdata Account
The company paying you (broker, carrier, or shipper) maintains an account with Comdata loaded with funds.
Express Code Is Generated
When you need funds (for fuel, lumper fees, etc.), they generate an express code—a 14-18 digit number tied to a specific dollar amount.
You Receive the Code
The express code is sent to you via phone, text, email, or through the Comdata app. You may also receive a pre-printed paper Comcheck.
Cash at Truck Stop or Deposit
Take the code to any participating truck stop (Pilot, TA, Love's, etc.) and convert it to cash. Or deposit it directly to your bank account.
Key Benefit
Once a Comcheck is cashed with a valid authorization number, the issuer cannot stop payment. This protects drivers from payment disputes after delivering a load.
Understanding Express Codes
The express code is the heart of the Comcheck system. It's a unique string of 14-18 numerical digits that authorizes a specific dollar amount. Here's what you need to know:
Example Express Code Format:
1234-5678-9012-3456
This code is tied to a fixed amount (e.g., $350 for a lumper fee)
One-time use: Each code can only be used once, then it's deactivated
Fixed amount: You can't use a partial amount—it's all or nothing
Time-sensitive: Some codes have expiration dates (usually 30-90 days)
Verifiable: Truck stops verify the code in real-time before releasing funds
Where to Cash a Comcheck
Comchecks can be cashed at most major truck stops across the country. The key is understanding the cash-back limits and fees at each location. Here's a breakdown of the major chains:
| Truck Stop | Cash Back Limit | Fee with Fuel | Fee w/o Fuel |
|---|---|---|---|
| Pilot Flying J | $200 | Free up to $200 | 3% of amount |
| TA / Petro | $300 | Free up to $300 | Varies by location |
| Love's Travel Stops | $200 | Free up to $200 | Fee applies |
| Sapp Bros | $500 | Varies | Varies |
Important Limits
Most truck stops have a maximum cash limit of $999.99 per transaction. For larger amounts, you may need to make multiple transactions or deposit the Comcheck directly to your bank account.
How to Cash at a Truck Stop
- 1.Go to the fuel desk or cashier window
- 2.Tell them you have a Comcheck to cash
- 3.Provide your express code (or paper Comcheck)
- 4.Show valid ID (driver's license required)
- 5.They verify the code electronically
- 6.Receive your cash (minus any fees)
Pro Tip: Fuel first to avoid the 3% fee on cash-back amounts. Even a small fuel purchase qualifies you for the fee-free cash back up to the limit.
Comcheck Fees Explained
There are two types of fees with Comchecks: what the issuer pays Comdata, and what you might pay when cashing it.
Issuer Fees (Broker/Carrier Pays)
- $4-$10 per $1,000 is typical for high-volume accounts
- Flat fee structure—costs same for $20 or $1,000
- Some brokers mark up to $10-$40 per Comcheck
Cashing Fees (You Might Pay)
- Free when fueling (up to $200-$300)
- 3% typical fee without fuel purchase
- Some locations charge flat $5-$10 fee
Common Uses for Comchecks
Comchecks are used for virtually any over-the-road expense that needs to be paid immediately. Here are the most common uses:
Lumper Fees
Pay warehouse workers to unload your freight
Typical: $200-$500
Fuel Advances
Get cash for fuel before completing a load
Typical: $200-$1,000
Cash Advances
Access cash for road expenses
Typical: Up to $999.99
Repairs & Maintenance
Pay for emergency truck repairs on the road
Typical: Varies
Tolls & Scales
Cover toll roads and CAT scale fees
Typical: $20-$100
Detention/Layover
Receive compensation for wait time
Typical: $50-$300
Lumper Fee Example
You arrive at a warehouse and they require a $350 lumper fee for unloading. You call your dispatcher or broker, who issues a Comcheck for $350. They give you the express code, you provide it to the warehouse, and they verify it instantly. The lumper fee is paid, and you can unload. This is much faster and safer than carrying $350 in cash.

Comcheck vs EFS: What's the Difference?
EFS (Electronic Funds Source), now part of WEX/Fleet One, is the main competitor to Comcheck. Both serve similar purposes but work differently:
| Feature | Comcheck | EFS Check |
|---|---|---|
| Issued By | Comdata Corporation | WEX / Fleet One |
| Format | Pre-printed check with express code | Blank check form you fill in |
| Flexibility | Fixed amount - all or nothing | Can use partial amounts |
| Authorization | 14-18 digit express code | Call for authorization numbers |
| Acceptance | Wider truck stop acceptance | Good at TA, Petro, Pilot |
| Fees | $4-10 per $1,000 typical | Similar fee structure |
Which Should You Use?
Most drivers don't get to choose—your broker or carrier determines which system they use. However, if you have a choice: Comcheck is more convenient with pre-printed checks and wider acceptance, while EFS offers more flexibility with partial amounts. Many carriers maintain accounts with both systems to maximize acceptance at different vendors.
Tips for Drivers Using Comchecks
Fuel First to Avoid Fees
Even a small fuel purchase ($50-$100) qualifies you for fee-free cash back up to $200-$300. Plan your Comcheck cashing around your fuel stops.
Write Down the Express Code
Don't rely solely on text messages or emails. Write the code down and keep it in your logbook. Phone batteries die at the worst times.
Verify the Amount Before Accepting
Make sure the Comcheck amount covers your expense plus any potential fees. If a lumper is $350 and you'll pay 3% to cash without fuel, you need at least $361.
Keep Your Receipts
Always get and keep receipts when cashing Comchecks. This protects you if there's a dispute about whether funds were received.
Watch for Comcheck Scams
Never accept a Comcheck from an unverified broker. Scammers may issue fake codes. Always verify your broker before accepting loads or payments.
