@Pete-S said in Do international TLD's have restrictions?:
For the .it TLD.
Who can register a .it domain?
"An unlimited numbers of .it domain names can be registered by anyone who is an adult and has citizenship, residence or commercial headquarters in the countries of the European Economic Area (EEA), in the State of the Vatican, in the Republic of San Marino and the Swiss Confederation."

Every country has their own NIC for their own TLD. Only some countries allow third parties to register, very few. More allow a citizen to register on behalf of a third party. Many don't allow that at all.
Italy requires a citizen to register on behalf of a third party (I'm a citizen, but it's a pay so use someone in country anyway). Colombia (that NTG uses) is open for anyone, that only opened up to the global public around 2010 and we got ntg.co literally in the first 15 minutes it was open having lost the lotto for niagara.co
