You updated your payment card.
The change went through successfully.
But when the next charge appeared — the currency was different.
USD became EUR.
KRW became USD.
The amount looks unfamiliar.
This usually happens due to regional billing routing — not pricing changes.
Why Currency Changes After Card Updates
- New card is issued in a different country
- Billing system auto-detects card region
- Payment gateway reroutes currency processing
- Original currency is no longer supported for that card
Billing currency often follows the card — not the account.
How This Affects Your Charges
- Exchange rates apply automatically
- Foreign transaction fees may appear
- Final amount may fluctuate monthly
- Bank conversion rates vary
This can make charges appear higher than expected.
How to Confirm the Correct Billing Currency
- Check invoice currency on billing page
- Review payment receipt details
- Contact support for region assignment
- Ask if currency override is available
Some services allow manual currency resets.
How to Avoid Currency Switching Issues
- Use a card issued in your billing country
- Avoid cross-region virtual cards
- Confirm currency before updating payment
Card region directly influences billing currency.
Always verify regional settings before switching cards.
