Road networks
The int_ref=* tag is not needed on roads where the ref=* tag is the same as the international reference.
E-road network (Europe/Eurasia)
The reference format is E followed by a space followed by up to 3 digits.
Examples:
A list of all the E-routes can be found on 
International E-road network; be aware, that writing in en-WP is not according to the definition of the e-roads which is with a space. Please only use a leading zero if it is used on physical signs in the relevant country, otherwise references on maps and in navigators will be inaccurate.

Relations of the international roads
International roads are mapped with relations 
of type=route.
Add to the relation all the ways that correspond to the international road. Since there are usually many ways, they are divided into sections. E.g. for countries or only sections of them, so that a maximum of 500 members are included.
