## Verify a bank account

There are two ways to verify a bank account as a payment method:

- Instant verification: Docker supports several major banks for instant verification.
- Manual verification: All other banks must be verified manually.

### Instant verification

To verify your bank account instantly, you must sign in to your bank account
from the Docker billing flow:

1. Choose **US bank account** as your payment method.
2. Verify your **Email** and **Full name**.
3. If your bank is listed, select your bank's name or select **Search for your bank**.
4. Sign in to your bank and review the terms and conditions. This agreement
allows Docker to debit payments from your connected bank account.
5. Select **Agree and continue**.
6. Select an account to link and verify, and select **Connect account**.

When the account is verified, you will see a success message in the pop-up modal.

### Manual verification

To verify your bank account manually, you must enter the micro-deposit amount from your bank statement:

1. Choose **US bank account** as your payment method.
2. Verify your **Email** and **First and last name**.
3. Select **Enter bank details manually instead**.
4. Enter your bank details: **Routing number** and **Account number**.
5. Select **Submit**.
6. You will receive an email with instructions on how to manually verify.

Manual verification uses micro-deposits. You should see a small deposit
(e.g. $-0.01) in your bank account in 1-2 business days. Open your manual verification email and enter the amount of this deposit to verify your account.

## Failed payments

> [!NOTE]
>
> You can't manually retry a failed payment. Docker will retry failed payments
based on the retry schedule.

If your subscription payment fails, there is a grace period of 15 days, including the due date. Docker retries to collect the payment 3 times using the following schedule:

- 3 days after the due date
- 5 days after the previous attempt
- 7 days after the previous attempt

Docker also sends an email notification `Action Required - Credit Card Payment Failed` with an attached unpaid invoice after each failed payment attempt.

Once the grace period is over and the invoice is still not paid, the subscription downgrades to a free subscription and all paid features are disabled.

## Redeem a coupon

You can redeem a coupon for any paid Docker subscription.

A coupon can be used when you:
- Sign up to a new paid subscription from a free subscription
- Upgrade an existing paid subscription

You are asked to enter your coupon code when you confirm or enter your payment method.

If you use a coupon to pay for a subscription, when the coupon expires, your payment method is charged the full cost of your subscription. If you don't have a saved payment method, your account downgrades to a free subscription.
