Iran is a destination with a unique travel experience but also many specific rules: limited payment options, clear dress requirements, and a different currency system. Getting these ten things clear before you go will help ensure a smoother trip.

1. Stay Updated on Safety Advisories: Before and during your trip, regularly check the latest travel alerts from your country’s foreign affairs department or consulate service, objectively assess risks, and purchase travel insurance that includes emergency medical and evacuation coverage.
2. Carry Enough Cash: International credit and debit cards (including UnionPay) are almost unusable in Iran. Be sure to bring sufficient U.S. dollars or euros in cash, exchange for Iranian rials upon arrival, and store your money in separate places.
3. Understand Toman vs. Rial: Most local prices are quoted in toman, where 1 toman equals 10 rials. Always confirm the currency unit before making a transaction to avoid accidentally paying ten times more.
4. Follow Dress Codes: Women are required to wear a headscarf and cover their arms and legs in public. This applies to foreign travelers too. It’s advisable to bring loose-fitting long-sleeved tops and long skirts or dresses.
5. Respect the Alcohol Ban: Alcohol is illegal in Iran. Do not bring, consume, or discuss alcoholic beverages in public.
6. Show Respect at Religious Sites: When entering a mosque, remove your shoes, stay quiet, follow gender-segregated areas and photography rules. Some sites have separate entrances for non-Muslims.
7. Ask Before Taking Photos: Always ask for permission before photographing people, religious sites, or government buildings. Photography is strictly prohibited at military facilities and certain sensitive areas.
8. Prepare for Internet Access: Some international social media and messaging apps are restricted. Bring a reliable communication solution and download offline maps in advance.
9. Be Aware of Ramadan Schedules: During Ramadan, business hours and dining availability change significantly during the day. Stay flexible with your plans and respect local customs.
10. Keep Emergency Contacts Handy: Carry copies of your passport and visa, and save the contact information for the embassy or consulate of your country in Iran. In case of emergencies, prioritize your personal safety.

In addition, Iran uses the Solar Hijri calendar (a Persian lunar-based calendar), which differs from the Gregorian calendar. Holidays and Ramadan schedules can affect business hours and travel plans, so check local holiday dates before you go. Internet and communication services are somewhat restricted, so prepare alternative ways to stay connected and save key information and offline maps in advance. Cities are often far apart, so try to schedule long-distance travel during the day. Carry drinking water and any necessary medications, and always put personal safety first in case of unexpected situations.
