Now every country has a travel advisory based on this system, which has replaced all the previous such advisories.
The United States on Wednesday unveiled a way to warn its citizens about the dangers of foreign travel, with a four-point safety ranking system for countries and an interactive world map.
The arch-nemesis of world's superpower, North Korea is also in Level Four, with the additional restriction that U.S. law prohibits American travellers from using their passports there, effectively banning visits to the Kim led-state.
The Department of State does not recommend travelling to Level 4 category countries.
Ms Michelle Bernier-Toth, acting deputy assistant secretary for overseas citizen services, said the changes were made as there was a need to make the information more accessible to people and more easily understood using plain language.
Bernier-Toth said this was the first major overhaul of its travel advisory system "in a very long time". Canada and Australia are among the countries ranked Level One.

While two army men successfully complete the drill, the third one falls straight to the ground, as the rope slips off the chopper. PTI reported that all exercises requiring security forces to slither down to the drop zone have been suspended by the Army.
"Terrorist groups continue plotting possible attacks in Pakistan". Although the rankings for safety have been announced according to nation, the State Department specified that in some cases the levels of safety may differ in different areas of a nation.
She added that the travel advisory will be reviewed on a regular basis depending on the rating level of the particular country and circumstances. The U.S. Department has placed Pakistan under level 3 category.
Level 4 is for do-not-travel countries, those with a "greater likelihood of life-threatening risks" in which the USA government may be limited in its ability to help. Travelers already in those countries are advised to leave as soon as it is safe.
Eleven countries come with the do-not-travel recommendation, most in Africa and the Middle East: Mali, Central African Republic, Libya, South Sudan, Somalia, Yemen, Syria, Iraq, Iran, Afghanistan and North Korea.
The advisory said that Indian authorities report rape is one of the fastest growing crimes in India whereas violent crime, such as sexual assault, has occurred at tourist sites and in other locations.
Officials insisted the change was to make advice clearer to U.S. citizens that plan to travel. The State Department's website says this designation is earned due to "health attacks directed at U.S. Embassy Havana employees" over the past several months, and Bernier-Toth said this is being taken seriously.
