Losing a corporate card can be stressful, but acting quickly and following the right steps will protect the company from fraud and ensure you can continue making business-related purchases without disruption. This guide outlines exactly what you should do.


1. Stay Calm and Act Immediately

The sooner you report a lost card, the easier it is to prevent unauthorised transactions. Don’t wait until you’re “sure” it’s missing—assume it’s lost after a reasonable search and notify the right teams.


2. Retrace Your Steps

Before you raise an alert, quickly check the most common places where corporate cards go missing:

  • Wallet, bag, laptop sleeve

  • Hotel room, rental car, conference venue

  • Your desk or company locker

  • Recently visited restaurants or stores

If you still can’t locate it, move to the next steps.


3. Report the Loss to Your Corporate Card Administrator

Notify your company’s finance or expense management team immediately. Provide:

  • Your full name

  • Card type/program

  • Approximate time or place you believe it was lost

  • Any recent transactions that look suspicious

Finance teams typically freeze the card instantly to prevent misuse.


4. Contact the Card Issuer (If Required)

Depending on company policy, you may also need to notify the card provider—such as Amex, Visa, Mastercard, or your bank.
Most issuers can:

  • Cancel the card

  • Reissue a replacement quickly

  • Monitor for fraudulent activity

Some companies prefer the finance team to contact the issuer for you, so check your internal process.


5. Check for Unauthorised Transactions

Review your recent expenses in your expense management system or banking app. Flag anything you don’t recognise to:

  • Your finance team

  • The card issuer (if requested)

Quick reporting helps ensure you’re not held responsible for fraudulent activity.


6. Update Upcoming Bookings or Payments

If your corporate card was used for:

  • Hotel reservations

  • Car hire

  • Subscriptions or recurring business tools

  • Conference registrations

You may need to update the payment method once the replacement card is issued.


7. Follow Internal Documentation Requirements

Your company may require:

  • A lost card report

  • A short written explanation

  • Manager approval for a replacement

Submit any forms promptly so the reissue process isn’t delayed.


8. Secure Your Replacement Card

When your new card arrives:

  • Sign it if required

  • Store it in a secure location

  • Update any saved payments

  • Follow company guidelines on card use and storage

Consider using digital wallet storage (where allowed) to reduce the risk of physical loss.


9. Learn From the Experience

To avoid future issues:

  • Keep the card in a consistent place

  • Use a dedicated card holder

  • Avoid storing the card loose in bags or pockets

  • Enable transaction alerts if available

Small habits go a long way toward preventing card loss.


Summary

If you lose your corporate card, the key steps are: act quickly, notify your finance team, report the card to the issuer if required, check for suspicious charges, and update any affected bookings or payments. The process is usually straightforward—and designed to protect both you and the business.
