In 2002 or 2003, BirdCage Software proposed ID3v1.2, which enlarged many of the fields from 30 to 60 bytes and added a subgenre field while retaining backward compatibility with v1.1 by placing its new 'enhanced' tag in front of a standard v1.1 tag. The modified format became known as ID3v1.1. In 1997, a modification to ID3v1 was proposed by Michael Mutschler in which two bytes formerly allocated to the comment field were used instead to store a track number so that albums stored across multiple files could be correctly ordered. The v1 tag allows 30 bytes each for the title, artist, album, and a 'comment', 4 bytes for the year, and 1 byte to identify the genre of the song from a predefined list of values. The method, now known as ID3v1, quickly became the de facto standard for storing metadata in MP3s despite internationalization and localization weaknesses arising from the standard's use of ISO-8859-1 system of encoding rather than the more globally compatible Unicode. Kemp deliberately placed the tag data (which is demarcated with the 3-byte string TAG) at the end of the file as it would cause a short burst of static to be played by older media players that did not support the tag.

In 1996 Eric Kemp proposed adding a 128- byte suffix to MP3 files in which useful information such as an artist's name or a related album title could be stored. When the MP3 standard was published in 1995, it did not include a method for storing file metadata. In ID3v2, an extensible set of 'frames' located at the start of the file are used. In ID3v1, the metadata is stored in a 128- byte segment at the end of the file. There are two unrelated versions of ID3: ID3v1 and ID3v2. It competes with the APE tag in this arena. ID3 is a de facto standard for metadata in MP3 files no standardization body was involved in its creation nor has such an organization given it a formal approval status.

It allows information such as the title, artist, album, track number, and other information about the file to be stored in the file itself. ID3 is a metadata container most often used in conjunction with the MP3 audio file format.
