"int_ref" stands for "international reference" and is used for international reference numbers or codes.

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.

Trans-African Highway network

The reference format is TAH followed by a space followed by digits. Example: int_ref=TAH 1

A list of all the TAH-routes can be found on  Trans-African Highway network.

Asian Highway Network

The reference format is AH followed by digits. Example: int_ref=AH1

A list of all the AH-routes can be found on  Asian Highway Network.

Waterway networks

E-waterway network (Europe/Eurasia)

Please use relations for international routes.

The format is "E" followed by a space, followed by a 2-digit number, e.g. int_ref=E 10

A list of E-Waterway-Relations can be found at WikiProject Europe/E-waterway network.
