Language: The language of Iran is Persian.
Tipping: Tipping is not expected although always welcome.
Electrical Current/ Plugs: The voltage is the same as the USA: 120V, 60 Hz. Almost all electricity connections in Iran are European round two-pin style however some parts of central Tehran still use the British plugs. There will probably be just one power point in your room, so plan ahead to charge all your gadgets. A small power board can also be useful to bring with you.
Religion: It is said that 99% of Iranians are Shi'a Muslims. The government does not recognise non-religious Iranians.
Water: Tap water is safe to drink in Tehran although bottled water is generally recommended.
Politics: Iran is a theocracy. According to its constitution, its laws and regulations must be based on Islamic criteria. There is a supreme leader who has the final policy decisions and a president who is elected for four years.
Culture: WOMEN: must wear a headscarf and loose-fitting clothing that doesn't outline your body shape and covers you to your wrists and ankles at all times, apart from in the privacy of your hotel bedroom. The headscarf can be of any colour and tied under the chin. It is acceptable for some hair to be shown, although in more traditional areas all hair may need to be covered. There is usually no problem with wearing open-toed sandals.
MEN: must wear full-length trousers. Short-sleeved shirts are acceptable but sleeveless 'singlet' tops are not acceptable. Open-toed sandals are now acceptable for men but ankles must still be covered by your trousers.
Alcohol is strictly forbidden in Iran and severe penalties will be incurred by anyone attempting to bring it into the country. Drug laws are also extremely strict and travellers face lengthy jail terms if caught.
