Understanding 'Which Of My Cards Did Not Work Yesterday' Emails
Ever since you and your drivers have started using the fuel cards, you have also been receiving emails called "WHICH OF MY CARDS DID NOT WORK YESTERDAY" during the morning hours on weekdays. These emails communicate the reason(s) why a driver may have faced difficulty using the card(s) the day before or over the weekend.
Here’s a quick and easy refresher on how to read those emails, starting with explaining what each of the 8 column headers mean:

- Site: This is the number that is associated with the fuel station.
- Card: The last 7 digits of the card used at the time of transaction. If your account is set under the Floating Pin system, this section will display the Driver Number.
- Jobber: The number that is assigned to your fuel card marketer or issuer.
- Acct: The number that is assigned to your account.
- Date: The date that the attempted transaction took place.
- Time: The local time of the fuel station that the attempted transaction took place.
- AuthCode: Can be ignored, as it is a deprecated function.
- Approval Status: Explains why the transaction was denied.
Denials: What They Mean and How to Prevent Them
The different Approval Statuses or reasons why the card was denied are all preventable by taking simple steps. A few seconds of planning and verifying that the card settings are properly set before the driver leaves will mostly ensure your driver fueling with no issues.
Below are the most common explanations and the possible causes, and how to fix and prevent them:
Explanation: Driver inputted the incorrect PIN/DID
How to Prevent: Remind the driver of the correct 5-digit PIN. Offer to make this a custom PIN for your driver so he/she may easily remember it.
Explanation: Fuel card is invalidated
How to Prevent: Revalidate the card by accessing your CFN customer portal (see below).
Explanation: Fuel site is in a blocked zip code or state, or is a ghost site.
How to Prevent: Redirect driver to nearest authorized station by using the CFN Site Locator (website or app).
Explanation: Card/driver has reached the day’s transaction limit
How to Prevent: Reset and revise the transaction count by accessing your CFN customer portal (see below).
Explanation: Card/driver has reached the day’s gallon limit, or the account gallon limit has been reached
How to Prevent: Reset and revise the daily gallon limit by accessing your CFN customer portal or revise the account gallon limit with the customer service team.
Explanation: This transaction was denied because the card swipe was attempted outside of allowed Time Profile.
How to Prevent: Access your CFN customer portal and reset the transaction count and ask driver to move to a different pump and/or please ask the driver to go into the store and do the transaction by swiping the card with the assistance of a cashier.
Explanation: The driver/card visited a site with previous reports of suspicious activity or has not visited that site for a long period of time.
How to Prevent: Corroborate with your driver that they are at the site in question and contact us immediately after for next steps.
Explanation: This transaction was denied because the card was swiped more than once in a short period of time before the card reader finished its card-reading process.
How to Prevent: Reset the transaction count by accessing your CFN customer portal (see below). If possible, have the driver move to a different pump in the same station.
