Choosing the correct BIN is one of the key factors for successful transactions. The right card option helps improve approval rates, reduce declines, and ensure smoother spending - especially for advertising and business payments abroad.
To make the search easier, a new tool has been added to the service - the “Merchant” filter.
Where to find the filter?
Log in to your Combo Cards account
Go to Virtual cards → Create
Select “Merchant” in the filter options
Choose the service you want to pay for (for example: an advertising platform, subscription service, hosting provider, etc.)
Check the suggested list of BINs and issue a card based on the selected option
All BINs displayed after selecting a merchant are relevant and optimized specifically for payments to that service.
Best practices when selecting a BIN
Start testing with the BINs suggested in the Merchant filter - this will give you the best initial approval rate
Before making a payment, ensure that your available account balance can cover all applicable fees
If payments fail for the selected BIN and the decline rate grows, you can always contact our support team for alternative options
To save a high-performing BIN, add it to your Favorites by clicking the ❤️ icon next to the BIN.
