How do I overcome validation error codes 81902 and 81924?

I'm here to share some insight about the error code codes 81902 and 81924 you encountered, kj. 

I'll ensure you can complete the card payment process for your QuickBooks Online subscription. 

Error 81902 and 81924 occur when your bank blocks or fails to authorize or validate a payment transaction related to QuickBooks. To help you resolve this, here are a few steps you can take:

1. Verify your payment details: Double-check that the payment information you've entered in QuickBooks Online is accurate, including your credit card or bank account details. Ensure there are no typos or discrepancies that could be causing the issue.
2. Contact your bank: Reach out to your bank's customer support and inform them about the error you're experiencing. Ask them if any blocks or restrictions on your account could prevent the payment. They may be able to provide insights or lift any restrictions if necessary.
3. Try an alternative payment method: If you're still facing difficulties with your current payment method, consider using an alternative payment method. 
4. Clear cache and cookies: Cached data or cookies stored in your browser can sometimes interfere with payment processing. Clearing your browser's cache and cookies can help resolve this issue. After clearing the cache, restart your browser and try making the payment again.
5. Ensure no special characters or symbols (such as @ or *) are in your billing address. Special characters cause errors.
6. Retry payment: After completing the above steps, attempt to make the payment again. Ensure that you follow the payment process within QuickBooks Online accurately. If the error persists, I suggest reaching out to QuickBooks Online Support for further assistance.
