Issue a reference number for Iran
Iran Visa with Official Invitation
To enter Iran, you need an official invitation or a valid reference number from the Iranian Ministry, regardless of the purpose of the trip. The only exception is a transit visa, where the consulate accepts the main visa for the final destination as proof of the purpose of the trip.
Invitation to Iran
Tourist invitation with the corresponding number for a tourist visa to Iran is issued by the Ministry of Foreign Affairs of Iran at the request of an accredited local tourist company. Business invitations, which are a mandatory requirement for obtaining a business visa to Iran, are also valid only if certified by the Ministry. An Iranian trading partner acts as a contact person for a foreign business traveler to arrange a valid letter.
In case of other intentions, such as journalistic activities, entry into Iran also requires permission from the competent ministry.
The invitation letter, also known as a visa support letter, usually contains, among other things, information about
- intention to travel, such as the purpose of the trip
- travel period
- number of planned entries
- places of stay
- applicant
- inviting party
Each approved invitation is assigned an individual number, which is required by the traveler when applying for a visa. The responsible consulate in the applicant's country also receives notification from the ministry.
The Iranian Embassy issues visas for a period approved by the relevant authority in Iran, i.e. the maximum length of stay depends on the invitation.
Attention: limited validity of the reference number
The reference number is valid for a limited time (approximately 20 days), during which you need to apply for a visa. After receiving the number, travelers should wait for 3 days before submitting documents to the embassy.
