One BIN per bank — the most common Visa or Mastercard product of each of the largest issuers, plus local-network BINs. All 1,167 BINs with a named issuer are in the Taiwan BIN list.

Local card networks in Taiwan

Besides the international networks, Taiwan has its own card scheme. Local networks matter for testing because their numbers often use prefixes that a Visa/Mastercard-only form rejects or labels wrongly.

Payment testing notes for Taiwan

Generated numbers only pass format checks: network prefix, length and the Luhn checksum. They are not issued by any bank in Taiwan, carry no money and are declined by every real payment system — use them for forms, validation and BIN rules, and switch to your gateway's documented test cards for approvals and declines.

Frequently asked questions

Can I generate a Taiwan credit card number for testing?

Yes. The generator on this page starts every number with a real BIN registered to a bank in Taiwan — by default 515717 (E. Sun Commercial Bank Co., Ltd, Mastercard credit). The remaining digits are random and the last one is a Luhn check digit. No bank issued the number, so it carries no account and real payments with it are declined.

Which card networks are most common in Taiwan?

By BIN count in our data: Visa 37%, Mastercard 36%, JCB 11%, UATP 8%. Local networks: JCB (145 BINs). Debit ranges make up 12% and credit ranges 88%.

Which BINs do Visa cards from Taiwan start with?

Examples from different banks: 416205 (Taishin International Bank); 402555 (Cathay United Bank); 414450 (Taiwan Shin Kong Commercial Bank). See the Taiwan BIN list for every bank.

Which currency should I use to test payments from Taiwan?

TWD (New Taiwan dollar). Gateway APIs usually expect amounts in the smallest unit (for example 1050 for 10.50). A card from any country can pay in any currency the merchant supports; the issuer handles conversion.

Will these numbers pass a payment gateway?

They pass format checks — length, network prefix and the Luhn checksum — so they are ideal for testing form validation and BIN-based rules. Gateways in test mode want their own documented test cards for approvals and declines; in live mode every generated number is declined because no bank has issued it.
