Address field - format of country

Hello, we are working on a connection between Pipedrive and Netsuite. Our developers are asking for the list of countries that are indicated in the address field. Is there a specific rule of language or ISO code to respect ? Thanks in advance !

This is a good question. You would find a lot more information here - Address fields in Pipedrive - Knowledge Base

It is better to stick to international standards like ISO 3166-1 alpha-2 - Wikipedia
