How to cancel Coinbase One by mail
Find your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Coinbase One is only as good as the details it quotes.
Prepare the letter
The letter asks Coinbase One to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Coinbase One”. Postbye fills it in from our English template.
Send the letter by certified mail
Mail the letter by certified mail to the San Francisco address in the next section, and keep the tracking number.
Keep the delivery receipt
Once the letter is delivered, the date on the receipt is the date Coinbase One was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Coinbase One, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
