New Taiwan LINE Pay applicants must also open LINE Pay Money. Registration country is determined by the phone number in LINE. Foreign applicants need an eligible Taiwan IC residence permit and the required Taiwan financial verification; holding a Singapore card does not meet these account requirements.

After opening LINE Pay Money, debit-card linking is limited to CTBC, Cathay United, Taipei Fubon, Union Bank of Taiwan, Taichung Commercial Bank, NEXT BANK, LINE Bank and Taiwan Business Bank. A Singapore-issued MPChat Visa debit card is outside this published issuer list and must not be presented as a supported debit card for these accounts.

Some users who were already using card payments before 3 December 2025 at 14:59 may temporarily use the older service without opening LINE Pay Money. Follow the current rules and prompts for that account. Visa branding and 3DS do not guarantee acceptance of a Singapore-issued MPChat debit card.

The Thailand Help Center allows corporate cards, with restrictions for some merchant types and online payments. Availability also depends on card type, issuing country and store. For an MPChat Singapore-issued Corporate T&E Visa debit card, check acceptance on the wallet’s payment screen and confirm that the issuer permits the transaction.

Use an eligible regional LINE Pay account and complete the identity checks required for that account. The card must permit online and overseas transactions and support 3DS. If the card is accepted, the official flow is LINE Pay → New Card, or Settings → Credit Cards; enter the requested card details and complete verification. At a participating merchant, choose LINE Pay and the linked card on the payment screen.

Thailand allows up to four linked cards per account. Review merchant conditions, payment limits and any fee before confirming. Limits published for payments from LINE Pay balance are not card-payment limits. Registering a card does not by itself add funds to the wallet or guarantee a merchant payment.

LINE Pay is no longer available in Japan. For Taiwan or Thailand, use an account that meets the local eligibility rules and check merchant and cross-border coverage for that account.

MPChat card 3DS codes are delivered to the linked email and MPChat notifications, not SMS. LINE’s own login or identity-verification messages are separate. If a card is rejected, use the actual regional rule and error; enabling 3DS does not override an unsupported issuing bank or card category.
