Hi Prokops,
Thanks for reaching out — I hope you’re doing well, and apologies for the delayed reply.
Regarding VAT validation for Norway, you’ll need to use the VATSense API key via the VATSense service. You can obtain a free API key (up to 100 VAT checks per month) by registering at: https://vatsense.com.
Once you have the key, go to:
WPFactory > EU VAT > Validation tab > VATSense.com API key
Enter your API key there. This step is required for validating VAT numbers from Norway, the UK, Australia, and Switzerland.
Please give that a try and let me know if everything works as expected.
Best regards,
WPFactory support team
