Pain Points
- 1Need for a standardized metadata container for MP3 tagging across software and hardware ecosystems.
- 2Fragmentation and differing adoption of ID3v2.3 vs ID3v2.4 (2.4 documented but not widely adopted due to disagreements).
- 3Interoperability challenges when ID3 tagging is applied to formats other than MP3 (e.g., Ogg Vorbis, WMA) where ID3 tags may not be compatible.
Key Features
- 1Metadata container providing fields like Title, Artist, Year, Genre for MP3s.
- 2ID3.org hosts format standards information, developer guidance, and pointers to libraries in multiple languages.
- 3Widespread software and hardware support cited (iTunes, Windows Media Player, Winamp, VLC; iPod, Creative Zen, Samsung Galaxy, Sony Walkman).
- 4ID3v2 documentation and related components (CHAP/CTOC, ATXT accessibility addenda, unofficial frames) described in the Developer Information section.
- 5TagLib library reference indicating support for MP3s with ID3v1/ID3v2/APE tags and other formats (Ogg Vorbis, FLAC, MPC).
Target Customer Industries
Competitive Advantages

Key Benefits
Additional Product Information
Product Description
ID3.org provides the format standards information and developer resources for the ID3 tagging data container used in MP3 files, enabling metadata tagging (Title, Artist, Year, Genre) and interoperability across software and hardware.
Target Market
Software developers and hardware/embedded device manufacturers building or maintaining MP3 tagging and metadata capabilities.
Unique Value Proposition
Official ID3 tagging standards plus comprehensive developer resources and interoperability guidance, helping ensure consistent metadata across MP3 ecosystems.
Technical Requirements
ID3v2 tags are designed for MP3 files; ID3v2.3 is the most popular version, with ID3v2.4 documented but less widely adopted. ID3v2 tags may not be compatible with non-MP3 containers (e.g., Ogg Vorbis, WMA). The TagLib library supports MP3s with ID3v1, ID3v2, or APE tags and other formats like Ogg Vorbis, FLAC, and MPC. Ogg Vorbis uses Xiph Comments; WAV has no tags; WMA has its own tagging format. ID3v2 Chapter Addendum (CHAP) and CTOC frames exist; ATXT provides accessibility tagging.
