The government of Israel has six forms of identification, each with different colored covers.
Dark blue IDs are reserved for Jewish Israeli citizens and gives the most freedom. Those who possess this identification can vote and are able to live anywhere in Israel and 80 percent of the West Bank.
Arab Palestinians living in Israel and the West Bank are given one of five ID types. The ID decides where they can and can’t live, and whether or not they can vote in Israeli Parliament.
The most entitled identification is blue and for Palestinian Citizens of Israel. Palestinians with this ID are allowed to vote in Israeli Parliament but forbidden from living in 68 percent of all towns in Israel.
The next type of ID is light blue and has dramatically less privilege than that of Palestinian Citizens of Israel. This ID is for East Jerusalem Palestinians. Palestinians with this ID are able to travel throughout most of Israel, but if they leave Jerusalem to live somewhere else then their ID can be revoked. These Palestinians cannot vote.
West Bank Palestinians have a light green ID. They are not allowed to vote and are restricted from living outside of 40 percent of the West Bank.
Since 2007 there has been the green ID, reserved for Gaza Strip Palestinians. These Palestinians cannot live outside of Gaza and are excluded from voting.
Finally, there are the Palestinian Exiles who have no ID. These Palestinians have no rights in Israel and are thus banned from stepping foot on the soil. There are an estimated 5.7 million of these individuals.
