ISAN code

I am looking for information to add ISAN code into my MP4 files.

under what TAG should I add ISAN code?

in Apple files... it looks like the ISAN code is added under Vendor.
but i cannot find any reference in mp3tag for Vendor tag.

Vendor : buenavista:isan:0000-0000-4C2E-0000-N-0000-0001-3

See this help page for field mappings:
http://help.mp3tag.de/main_tags.html

Does the field ISRC help?

my understanding is that they are not the same.

SRC codes are always 12 characters long, in the form "CC-XXX-YY-NNNNN"

ISAN is 26 characters, in the form 0000-0000-03B6-0000-O-0000-0000-2
https://en.wikipedia.org/wiki/International...iovisual_Number

http://id3.org/id3v2.3.0 only mentions ISRC ...

Maybe you can name the tagfield ISAN ...
...search there for ISAN ...
