Iran route numbering system is a network of highways and roads in Iran that is managed by Iran Road Maintenance & Transportation Organization. The network comprises main highways and several major and minor country roads.
History edit
Probably in the late 1990s, all road numbers were changed. The old system was also a grid, but with only 5 east-west routes (even numbers 2-10) and only 7 north-south routes (odd numbers 1-13). Therefore, the new system is a lot denser, though there are a few sections that used to have a number that is not numbered anymore.
Route signs edit
blue on motorways, green on other roads. 3-digit numbers appear in black on a white rectangle

Odd numbers (11-99) generally denote north-south routes, while even numbers (12-98) denote east-west routes. Numbers increase in eastbound and southbound direction respectively. There are some A roads without a national number. Motorways do not have national numbers. 3-digit numbers are derived from 2-digit numbers by adding a digit at the end.
