Official use, and grammatical use differs.
Officially, as designated by the United Nations, only one country holds this title:
The Former Yugoslav Republic of Macedonia (the name it is referred to by the UN, instead of 'Macedonia')
Officially, by the formal names of each country, you can add two more:
The Bahamas
The Gambia (why, for both, is coming soon)
If you remove prefixes, such as 'Republic of' or 'Kingdom of', you can also add these:
Union of the Comoros
Republic of the Congo
Democratic Republic of the Congo
Republic of the Marshall Islands
Kingdom of the Netherlands
Republic of the Philippines
Republic of the Sudan
Grammatical (popular) usage has certain attributes:
Any plurals or multiple entities (the United States, the United Kingdom, the Netherlands, the Russian Federation, the United Arab Emirates)
Any islands, also plural (the Bahamas, the Maldives, the Marshall Islands, the Seychelles, the Solomon Islands)
Any specifiers (the Czech Republic-- a 'Czech' Republic, the Saudi Arabia, the Dominican Republic, the South Sudan)
Arguable:
When a specific geographic feature is also a name (for example, if 'the Rock' or 'the Ridge' were also a country's name)
The Gambia, from earlier, also fits this, referring to a river
The Sudan, refers to the similarly named region south of the Sahara
Disputed: examples such as the Lebanon (referring to Mount Lebanon), the Ukraine (referring to ukrayina, or 'the borderland')
What's an inexcusable example?
'The Iraq' as coined by Miss Teen South Carolina in 2007
'the Ukraine' as its been appearing in the news, was how Americans referred to it when it was part of the USSR, indicating a region (the 'ukrayina', or 'the borderland') much like how we'd refer to 'the Badlands', 'the tundra', or 'the Rockies' as regions, and not governments
