Cardlock Credit Check

Dear Valued Cardlock Customer,

As an important reminder regarding credit card limits at our Cardlock locations:

➤ Effective April 1, 2026 our card readers will electronically check existing credit limits and available balances for all Cardlock transactions. You may experience a declined transaction if your current credit limit is not sufficient to cover your fuel purchase.

To avoid any disruption in service, we strongly encourage you to review your current credit limit and contact our Credit Department to apply for an increase if needed. Taking action now will help ensure seamless access to Cardlock services when you need them most.

If you have any questions or would like to discuss your options, our team is happy to help.

Please contact us at 403-528-6600, Monday to Friday from 8:00 a.m. to 4:30 p.m.

Thank you for your continued business and cooperation.
