Passports of the European Union

The European Union itself does not issue ordinary passports, but ordinary passport booklets issued by its 28 member states share a common format. This common format features burgundy-coloured covers (with the exception of Croatia) emblazoned—in the official language(s) of the issuing country (and sometimes its translation into English and French)—with the title "European Union", followed by the name(s) of the member state, its coat of arms, the word "PASSPORT", together with the biometric passport symbol at the bottom centre of the front cover.

Some EU member states also issue non-EU passports to certain people who have a nationality which does not render them citizens of the European Union (e.g., British Overseas Territories Citizens except those with a connection to Gibraltar, British Protected Persons and British Subjects).

In addition, the European Commission issues European Union Laissez-Passers to the members and certain civil servants of its institutions.

European Union

The European Union (EU) is a politico-economic union of 28 member states that are located primarily in Europe. It covers an area of 4,324,782 km², with an estimated population of over 508 million. The EU operates through a system of supranational institutions and intergovernmental-negotiated decisions by the member states. The institutions are: the European Parliament, the European Council, the Council of the European Union, the European Commission, the Court of Justice of the European Union, the European Central Bank, and the Court of Auditors. The European Parliament is elected every five years by EU citizens.

The EU has developed an internal single market through a standardised system of laws that apply in all member states. Within the Schengen Area, passport controls have been abolished. EU policies aim to ensure the free movement of people, goods, services, and capital, enact legislation in justice and home affairs, and maintain common policies on trade,agriculture,fisheries, and regional development. The monetary union was established in 1999 and came into full force in 2002. It is currently composed of 19 member states that use the euro as their legal tender.

Number

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, and so forth. A notational symbol that represents a number is called a numeral. In addition to their use in counting and measuring, numerals are often used for labels (as with telephone numbers), for ordering (as with serial numbers), and for codes (as with ISBNs). In common usage, the term number may refer to a symbol, a word, or a mathematical abstraction.

In mathematics, the notion of number has been extended over the centuries to include 0, negative numbers, rational numbers such as and , real numbers such as and , complex numbers, which extend the real numbers by including , and sometimes additional objects. Calculations with numbers are done with arithmetical operations, the most familiar being addition, subtraction, multiplication, division, and exponentiation. Their study or usage is called arithmetic. The same term may also refer to number theory, the study of the properties of the natural numbers.

Switzerland

Switzerland (/ˈswɪtsərlənd/), officially the Swiss Confederation (Latin: Confoederatio Helvetica, hence its abbreviation CH), is a country in Europe. While still named the "Swiss Confederation" for historical reasons, modern Switzerland is a federal directorial republic consisting of 26 cantons, with Bern as the seat of the federal authorities, called Bundesstadt ("federal city"). The country is situated in Western and Central Europe, and is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of 41,285 km² (15,940 sq mi). While the Alps occupy the greater part of the territory, the Swiss population of approximately 8 million people is concentrated mostly on the Plateau, where the largest cities are to be found: among them are the two global and economic centres, Zürich and Geneva.

The establishment of the Swiss Confederation is traditionally dated to 1 August 1291, which is celebrated annually as the Swiss National Day. The country has a long history of armed neutrality—it has not been in a state of war internationally since 1815—and did not join the United Nations until 2002. Nevertheless, it pursues an active foreign policy and is frequently involved in peace-building processes around the world. In addition to being the birthplace of the Red Cross, Switzerland is home to numerous international organizations, including the second largest UN office. On the European level, it is a founding member of the European Free Trade Association, but notably it is not part of the European Union, nor the European Economic Area. However the country does participate in the Schengen Area and the EU's single market through a number of bilateral treaties.
