You can subscribe to an individual Substack publication on the web by choosing its paid plan and entering a card at checkout. This guide explains how to prepare a Coinepay virtual card, complete Substack’s checkout, manage the subscription, and respond if a payment is declined. Card acceptance depends on the checkout and payment checks; having a virtual card does not guarantee a successful purchase.
What you need before subscribing
- A publication with paid subscriptions enabled. Substack subscriptions belong to individual publications, not to Substack as a whole. A publication may offer Free, Monthly, Annual, and Founding Member options. The options you see depend on what its publisher has enabled.
- A Substack email address. Use an email address you can access for sign-in, subscription notices, and payment-update messages.
- A Coinepay virtual card. Register with Coinepay and complete identity verification before using card services. Once your card is issued, its number, expiry date, and CVV are available through Coinepay. Check the app or self-service dashboard for your available funds and any card settings relevant to the purchase.
- Your real billing details. Enter your own name and accurate billing information. Do not use an invented address or another person’s identity to try to satisfy a payment check.
Each publication sets its own subscription prices, so there is no single Substack paid-subscription price. Review the publication’s current plan page and the final checkout amount before paying. A displayed local-currency price may depend on the publication and your location; readers cannot independently select a different billing currency on Substack.
How to subscribe with a Coinepay virtual card
- Open the publication on the web. Go to the publication you want to support and select its subscribe option. Its /subscribe page may first ask for your email address if Substack does not recognize you; a signed-in reader may go directly to the plans.
- Choose the subscription you want. Select Monthly, Annual, or Founding Member if offered. Free does not require a paid card checkout. Read the publication’s plan description: a Founding Member tier may have different benefits, and a paid subscription to one publication does not unlock another publication.
- Review the checkout amount. Check the billing period, currency, and amount shown before continuing. Monthly and annual subscriptions renew automatically unless you cancel before renewal. Web and iOS in-app prices need not match, so compare the checkout you intend to use.
- Select card payment at web checkout. If a previously saved card appears for your signed-in Substack account, check which payment method is selected before confirming. Enter your Coinepay card number, expiry date, and CVV when the checkout presents card fields, together with your real billing details. If an Apple device presents Apple Pay first, look for “Other subscription options” to enter a card on the web.
- Complete any requested verification. If checkout asks for a bank or cardholder authentication step, follow the on-screen instructions. Do not repeatedly submit the payment while a verification step is pending.
- Confirm and check your subscription. Submit only after reviewing the final details. Once Substack confirms the purchase, check that the publication appears under Subscriptions in your Substack settings. Keep the confirmation or invoice for your records.
Using the publication’s web checkout is especially important if you intend to enter the Coinepay card directly. For eligible publications, Substack may instead offer an Apple in-app purchase in its iOS app. According to Substack’s iOS guidance, only U.S. readers receive an in-app link to finish a card purchase on the web; international readers upgrading in the iOS app see the Apple purchase route. You can open the publication in a web browser to look for its web subscription checkout.
If your Substack card payment is declined
A decline does not, by itself, identify the cause. Substack notes that an issuer can decline a renewal, including for suspected fraud. Work through the checks below rather than changing your identity or location details to make a payment go through.
- Insufficient available funds: Compare the available funds shown in Coinepay with Substack’s final checkout amount and currency. Leave room for any applicable conversion or other charges shown to you. If you need information about Coinepay funding or charges, check the app or contact Coinepay support; do not assume the displayed subscription price is the only amount relevant to your card balance.
- Billing-detail mismatch: Recheck the card number, expiry date, CVV, name, and billing address you entered. Correct typing errors and use your genuine billing details. If Substack has prefilled an older payment method, make sure you have selected the card you intend to use.
- Authentication or 3-D Secure: If checkout presents an authentication challenge, complete it promptly using the available instructions. If the challenge fails or you cannot access it, check your Coinepay app or dashboard for relevant card activity and ask Coinepay support what to do next. Do not assume every Substack checkout will present the same verification screen.
- Merchant or regional checks: Payment methods and subscriptions can vary by checkout context, publication, and region. Confirm that the publication offers a paid plan and that card entry is available in your web checkout. Use your actual country and billing information; a virtual card cannot bypass Substack’s eligibility rules or payment checks. If you need help identifying why a genuine payment was rejected, contact Substack about the checkout and Coinepay support about the card.
- Expired or replaced card: Verify that the card details you submitted are current. If you already subscribe, update the saved payment method on Substack’s website before the next renewal.
If a renewal fails, watch for Substack’s email with instructions to update your payment information. Substack says readers have a two-week window to resolve an uncollected card renewal before their paid subscription reverts to free. Check the subscription status rather than assuming an attempted renewal succeeded.
How to update, cancel, or review your subscription
For a subscription paid by card, open substack.com/settings on the web, then go to Subscriptions → the publication → Payment Information to edit its payment method. Substack says card-payment changes are made on the web, not in its app. You can also review billing history and invoices in that publication’s subscription settings.
To stop a monthly or annual subscription renewing, use Settings → Subscriptions → the publication → Account actions on the web and cancel before the next renewal. Paid access normally continues through the period you already paid for; cancellation alone does not refund earlier charges. Refunds are generally at the publisher’s discretion, subject to Substack’s stated exceptions and conditions. If you subscribed through Apple in-app purchase instead of web card checkout, manage cancellation and refund requests through Apple.
Keep your Coinepay card details private and review both the publication’s plan terms and Substack’s checkout before confirming. If you cannot tell whether a charge completed, check your Substack subscription and billing history alongside the card activity in your Coinepay dashboard before trying again.

FAQ
Does one paid Substack subscription cover every publication?
No. Monthly, Annual, and Founding Member subscriptions are for individual publications. Check each publication’s plans and prices separately.
Where do I change the card for my Substack subscription?
On the web, go to substack.com/settings → Subscriptions → the publication → Payment Information. Substack does not offer this card-payment edit in its app.
Why was my Coinepay card declined on Substack?
Possible causes include insufficient available funds, incorrect card or billing details, an incomplete authentication step, or a payment check. Review the checkout details and contact Coinepay support about the card if needed.
Can I cancel my Substack subscription without losing access immediately?
Paid access normally continues until the end of the period you paid for. Cancel on the web under Settings → Subscriptions → the publication → Account actions before the next renewal.
