Why a Transaction May Be Declined
A card transaction may be declined for different reasons, including:
insufficient available balance
spending limits or transaction limits reached
the merchant is restricted
the country is blocked
the transaction amount is above a limit
too many transactions were attempted within a short period
the merchant category is blocked
merchant-side acceptance or processing issues
security checks such as CVV or 3DS verification failed
💡 Pro tip: A decline does not always mean there is a problem with your card. In many cases, the payment is blocked automatically by a risk rule.

Drug stores and proprietary drugs (5122)
Antique shops and pawn shops (5932–5933)

These categories are blocked to reduce the risk of fraudulent or regulated transactions.
⚠️ Important: Even if a merchant appears legitimate, the transaction may still be declined if the merchant is classified under a restricted MCC.
Restricted Merchants
Kolo may also restrict certain individual merchants based on internal risk controls.
Because merchant restrictions can change over time, a merchant may be declined even if it worked before.

Advertising Payments
Kolo cards can be used for advertising spend, but ad platforms often make repeated billing attempts, which can trigger velocity rules.
Meta / Facebook Ads
For Meta Ads, keep in mind:
more than 40 advertising transactions within 2 days may trigger a decline
high-volume ad accounts may benefit from using multiple cards
using separate cards can also help with reconciliation and spend control
💡 Pro tip: If you run heavy ad spend, it is often better to split activity across multiple cards instead of relying on a single card for all billing attempts.
Google Ads
Google Ads generally works well with Kolo cards.
However:
some first-time attempts may be declined
the platform may retry automatically
small verification attempts or temporary checks may happen before regular billing starts
If the first attempt fails, retrying often works.
Recurring Subscriptions
Some subscription merchants may decline the first attempt even if the card is valid.
This can happen because of:
merchant-side risk checks
first-time card verification
recurring billing setup behavior
If this happens:
retry the payment
check whether 3DS is required
try the same card again after a short delay
try a different card if needed
💡 Pro tip: A failed first subscription attempt does not always mean the merchant is unsupported.
Merchant-Side and Verification Issues
Sometimes a payment is declined even though your card is active and funded.
This may happen because:
the merchant’s payment processor rejects the card
the merchant applies BIN or region filters
the merchant blocks certain debit, virtual, or business card scenarios
the checkout flow fails during verification
3DS or OTP confirmation is not completed successfully
Common Decline Scenarios
Common decline scenario | What it means |
Too many transactions in a short time | If you make several payments too quickly, the card may be declined by a rapid transaction or daily velocity rule. |
Merchant or MCC restriction | The transaction may be blocked because the merchant falls under a restricted category or is on an internal restricted list. |
Blocked country | A transaction may be declined if the merchant is located in or processed through a restricted country. |
Incorrect CVV attempts | Too many incorrect CVV attempts may temporarily block further transactions. |
Transaction amount above a rule limit | Some categories such as fuel, gaming, ads, or ATM withdrawals have specific amount or velocity limits. |
What To Do If Your Transaction Is Declined
Check your card balance — Make sure you have enough funds
Check card status — Ensure your card is active and not locked
Review limits — You may have hit a daily or monthly limit
Check merchant — The merchant may be in a restricted category or country
Wait and retry — If you hit velocity limits, wait a few minutes before trying again
Try Apple Pay or Google Pay — Wallet payments work better than manual card entry
Try a different card — if the issue is merchant-specific or related to card-level risk rules
Check 3DS or OTP delivery — The transaction may fail if verification was not completed in time
