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:
- Invalid ID: The number does not exist in the official database. You can verify yours at the VIES VAT number validator.
- Cross-Border Restrictions: Your ID might be valid domestically but not authorized for EU-wide transactions.
- 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.

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 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.
