Why cards get declined buying tickets abroad

The usual causes

• International transactions not enabled. Many cards default to domestic use only. The most common cause and the easiest to fix.
• The bank blocking it as suspected fraud. An unfamiliar merchant, a large amount, from another country, in the middle of the night: exactly the profile a fraud system stops.
• The platform not accepting foreign-issued cards. Some domestic platforms only take local cards, and no amount of retrying changes that.
• Mismatched details. Name, address or postcode entered differently from what the bank holds.
• Transaction limits. A daily or per-transaction limit lower than the ticket price.

What to do before the on-sale

• Ask your bank to enable international transactions on the exact card you will use.
• Tell the bank a foreign transaction is coming, if it offers a travel notice.
• Check per-transaction and daily limits, and raise them if needed.
• Save the card to the platform account in advance rather than typing it during a countdown.
• Have a backup method, but one the platform actually accepts, not just any method.

A safety warning

Nobody needs your banking password or an OTP to buy you a ticket. If someone asks, it is a scam, without exception.

Likewise, do not send photographs of both sides of your card. A legitimate proxy service uses its own card and collects from you separately.

When the platform will not take a foreign card

This one cannot be prepared around. If a platform only accepts domestic cards or requires local verification, you need someone in that country to buy, which is the gap proxy booking exists to fill.

Establish this before the on-sale by reading the payment section of the show’s terms, rather than discovering it at the final step.
