Format details
There are two major versions. ID3v1 defines a fixed-length data block that is always placed at the end of the file. ID3v2, which has very little in common with ID3v1, defines a block with variable-length frames and allows more flexibility and verbosity.
As of 2017, it seems there are essentially three versions of ID3v2 to be aware of: v2.2.x, v2.3.x, and v2.4.x. These formats have many similarities, but are different in detail, and are not compatible in any way.
Identification
An MP3 file with an ID3v2 tag begins with ASCII "ID3".
For an MP3 file with an ID3v1 tag, ASCII "TAG" appears beginning 128 bytes from the end of the file.
