When we extract customer tax IDs and validate them through the EU VAT validation system (VIES), we currently use GR as the country code. However, VIES requires the use of EL, which means the Finance team has to manually change the country code before uploading the data.

To address this, I created a new country code entry for Greece using EL, but I’m reconsidering this approach. It doesn’t seem appropriate to have two ISO codes representing the same country, as this could lead to inconsistencies in our system (I have deleted the country code EL again).

I’d appreciate your thoughts on how we should handle the ISO country code setup for Greece. Should we stick with the official ISO code GR, or is there a better way to align with VIES requirements without compromising data integrity?
