Who knows how much time I’ve wasted over the years trying to find a reliable data source for country names, ISO codes, phone prefixes and currencies.
I have my own personal dysfunctional set of tables built manually from bits and pieces found online. But the other day I ran into this beauty: and updated ISO 3166 and ISO 4217 country and currency codes, with some FIFA and ITU codes thrown into the mix. The list is provided in CSV and JSON format and is now my one-stop solution for country codes.
