“Tax ID is Invalid” – How to Fix This Error
When entering your VAT or Tax ID in the Billing Information section, you may see the following error:

How to Fix It?
Check the selected VAT Country.
Make sure it matches the actual registration country of your business.
Remove any invalid characters.
Only numbers and letters are allowed in most VAT ID formats.
Example: 3421341 instead of $@3421341.
Validate the format.
Use an online tool like VIES (for EU VAT IDs) to check the valid structure.
For example, a German VAT ID should look like DE123456789.
