Iranian license plates have had European standard dimensions since 2005. Each province in Iran has multiple unique, two-digit codes that are included at the right end of the license plates in a distinguished square outline, above which the word ایران or "Iran" has been written. A province's license plates will not be issued with a new code unless all possible combinations with the old code have been issued. In Tehran, the first code to be issued for the province was code 11, and subsequent codes all increased by 11 as well (meaning codes 11, 22, 33, ..., 99 are unique to Tehran.) Ever since code 99 was fully issued, the new codes for Tehran have started from 10 and subsequently increased by 10. Most province codes increased by 10 based on the first code issued for their province. Khuzestan Province, for example, has been allocated codes 24 and 14, and code 24 will not be used before code 14 is fully issued. However, as codes started getting exhausted, numbers and letters have been assigned more liberally and without following this rule of thumb anymore Iran's license plate format is entirely in Persian alphabet. It follows the format ## X ### - NN

Letter series

Iranian license plates are entirely in Persian alphabet. This includes the numbers as well as the letter series. Below is the list of letters and the vehicle type to which they're assigned

Numbers

Iran's license plates use Persian numerals as opposed to Western Arabic numerals. Below is a table for reference:

Private vehicles

The plate is black on white. The code in the square represents the regional codes. The letter ب can be dependent on where the car's owner's principal address is located. For example, while regional code 24 belongs to Khuzestan Province, letter ب (B) is dedicated to residents of Abadan County, while letter ج (J) is dedicated to Khorramshahr County residents. The distribution of the letters has become more complicated with codes and letters being filled up, as some letters have been broken down even more, based on the initial two numbers on the license plates, and as some letters been given to multiple counties, who previously had separate letters from each other. Nevertheless, a new policy has emerged in 2021, which is a policy of recycling previously issued but no longer in circulation numbers. It is estimated that the total capacity of Iran's numbering system is about 62 million. So far, 55 million numbers have been issued, with 60% of them no longer in circulation, and only 23 million numbers on the streets.

Private vehicles of people with disabilities

The plate is black on white. To distinguish the type of the plate, there is a wheelchair symbol. The code in the square represents the regional codes.

Political and services plates

So far, 133 countries have been numbered. For each country's embassy, the first two digits increase (11D, 12D or 11S, 12S). These license plates are issued nationally, starting from regional code 11 regardless of which province the vehicles serves.

Provincial codes and letter series

Provincial codes are generally given to each province. There are some exceptions to this however. As was mentioned in the list of exceptions, within each province, letters are designated to each county. When each letter is exhausted, a new letter from the same provincial codes is granted. When the entire code is exhausted, the province is granted a new code, from which new letters are granted. For example, while provincial code 24 belongs to Khuzestan Province, letter ب (B) is dedicated to residents of Abadan County, while letter ج (J) is dedicated to Khorramshahr County residents. The distribution of the letters has gotten more complicated with codes and letters being filled up, as some letters have been broken down even more, based on the initial two numbers on the license plates, and as some letters been given to multiple counties, who previously had separate letters from each other. Within each province, registration numbers for all types of vehicles with the exception of private vehicles, are given province-wide, regardless of in which county the owner resides. Some types of vehicles such as police cars and diplomatic plates are allocated nationally, starting from code 11, regardless of the province in which they serve.

Provincial codes

License plates follow the format ## X ### / NN. The NN portion is a two-digit code granted to provinces.

Breakdown of codes and letters

The below 13 letters are used in private vehicle license plates. Number 0 (zero) is only used in the provincial code, and only in the newly granted provincial codes, after 99 has been exhausted. Zero has not been used in the five-digit registration number.

Provincial codes 10 to 19

Provincial codes 20 to 29

Provincial codes 30 to 39

Provincial codes 40 to 49

Provincial codes 50 to 59

Provincial codes 60 to 69

Provincial codes 70 to 79

Provincial codes 80 to 89

Provincial codes 90 to 99

Motorcycles

Motorcycle registration plates have a unique and different format. Motorcycle plates come in XXX - #####. XXX is a three-digit provincial code, followed by #####, a five-digit number. These license plates are issued provincially. Below is a list of codes and their corresponding provinces. Note that neither the three-digit provincial code, nor the five-digit registration number can take zero. Thus, for example, after provincial code 499, comes provincial code 511.

Free trade zones

The plate is black on white and consists of a five-digit number written once in Persian digits on the top and in Arabic digits on the bottom. On the left, there is an Iranian flag and the logo of the respective free trade zone with its name written in English below it. The size of the plate is American standard. Below are a few examples of these plates.
