How to cancel UnionPay by mail
Start with your account details
UnionPay will look your account up from what the letter says, so check the account email, the last four digits of the linked bank account or card and the membership tier first.
Draft the request
The request is prepared in Chinese (template zh), under the subject line “主题：取消请求 – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Post the letter
Mail the letter by certified mail to the Shanghai address in the next section, and keep the tracking number.
Keep proof the letter arrived
The receipt dates your request. Look at your next statement for any UnionPay charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel UnionPay, check these
- Check your bank statement after the cancellation date for any further charge.
- Settle any outstanding balance first. Closing a membership does not clear what you owe.
- Ask for the direct debit or card authorisation to be ended, not only the membership.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
