In a statement, it further said about 542,000 trucks had crossed the country's border checkpoints points during the nine month period which is 13 percent more than the figure for the same time-span in 2016, Press TV reported.
The trucks transported goods from over 100 countries, the IRICA added in its statement.
It added that the volume of cargos transited through Iranian territory over the same period had also increased by 13 percent in weight to reach 8.2 million tons.
In September, Iran announced a surprise rise of around 24 percent in transit of goods through its territories over a period of five months starting March 21, 2017.
Figures released by Iran's Road Maintenance and Transportation Organization (IRMTO) showed that over 4.17 million tons of goods had been moved through 32 active land and maritime borders during the period.
The IRMTO statement pointed to domestic media reports that Shahid Rajaee Port in the southern city of Bandar Abbas remained Iran's most important port through which 35 percent of the country's total trade activities were conducted.
The next key transit points were Parviz Khan and Bazargan checkpoints that respectively open to Iraq's Kurdistan region and Turkey's east.
The bulk of goods transported through border points included non-oil products such as fuel oil, textiles, auto parts and food products whose total weight stood at 2.78 million tons.
