## Troubleshooting VAT ID Errors

We use the European Union's **VIES** system to validate IDs. If your ID is rejected, it is usually due to one of these three reasons:

1. **Invalid ID:** The number does not exist in the official database. You can verify yours at the [VIES VAT number validator](http://ec.europa.eu/taxation_customs/vies/?locale=en).
2. **Cross-Border Restrictions:** Your ID might be valid domestically but not authorized for EU-wide transactions.
3. **System Outages:** If the VIES system in your specific country is temporarily down, we cannot verify the ID. If this happens, please wait a few hours and try again.

There may be certain situations in which a submission might turn up an error.

## Our Refund Policy

Tapfiliate subscriptions are paid in advance and are **non-refundable**, in whole or in part, including when you cancel or downgrade.

* **Charged in error:** If we charged you by mistake, we refund that amount, provided you report it to our support team within **30 days of the charge**.
* **Important:** If you have a question about a charge, contact [support@tapfiliate.com](mailto:support@tapfiliate.com) first and **please do not file a dispute** with your bank. Disputes freeze the transaction and significantly delay our team's ability to resolve it.
