AI 快速回答
Rights workflows should be documented before release, not reconstructed during a dispute.
- Save license PDFs or screenshots with timestamps.
- Keep split sheets and contributor approvals in the project folder.
- Record territory, term, allowed uses, and payment terms for each asset.
This is operational education for producers, not legal advice. For a signed deal, dispute, takedown, or high-value sync, ask a qualified music lawyer in the relevant territory.
Localization note
Legal, tax, privacy, rights, royalty, and contract guidance changes by jurisdiction. Treat this article as an editorial starting point, not legal or accounting advice.
For Traditional Chinese readers in Taiwan, Hong Kong, and Macau, verify local payment rails, tax paperwork, platform access, rights administration, and consumer rules instead of reusing mainland or US defaults.
快速解答
ISWC 標識詞曲作品，UPC 標識單曲/專輯這個發行產品，ISRC 標識具體錄音。一個正式發行的 track 通常會同時關聯三者，它們幫助平臺、發行商、版權整理和權利人把播放、銷售和版稅匹配到正確物件。
三類核心音樂標識
ISRC identifies a recording, ISWC identifies a composition, and UPC/EAN identifies a release product. They do not grant rights by themselves, but bad identifiers can misroute royalties and claims.
Treat clearance as chain-of-title work: who owns the recording, who owns the composition, what use was approved, what territory and term apply, and who gets paid.
A credit line, DM, beat-store receipt, or friendly verbal yes can be useful evidence, but it is not the same as a license that names the rights and permitted exploitation.
ISRC
Identifies a specific recording or version.
Producer action Assign one per final master, remix, live version, or edit that is distributed.
ISWC
Identifies the underlying composition.
Producer action Register the work and splits with the correct PRO or society.
UPC/EAN
Identifies the release product.
Producer action Use distributor release metadata consistently across stores.
三者如何連線
何時生成各類程式碼
UPC 和 ISRC 通常在你透過發行商上傳發行時生成。ISWC 通常在你向 PRO 或作品登記系統提交詞曲作品後生成。
| Territory | Operational caution |
|---|---|
| US | Separate master, composition, mechanical, performance, sync, and DMCA processes. SoundExchange applies to non-interactive digital performance royalties for recordings. |
| EU/EEA | Moral rights and collective-management rules can be stricter than a US-only workflow. Platform takedowns and neighboring rights can involve local societies. |
| UK | PRS, MCPS, and PPL often sit in different parts of the rights stack. Do not assume a US PRO registration covers UK exploitation cleanly. |
| Brazil | ECAD and local publishing administration can affect public performance and neighboring-right collections. Portuguese contract language may matter. |
| Russia | Local collection and enforcement conditions can change quickly. Keep contracts, source files, and payment evidence in case platforms request proof. |
| China | Platform clearance, lyric use, and local distribution rules may require local partner review before release or sync use. |
| Japan/Korea | JASRAC, NexTone, KOMCA, and local neighboring-right workflows can be precise about splits, covers, and sync. Metadata accuracy matters. |
| Turkey/Indonesia | Local collecting societies and platform policies may diverge from US templates. Confirm language, term, and territory in writing. |
| Spanish multi-region | Spain, Mexico, Colombia, Argentina, Chile, and other Spanish-speaking markets are not one legal region. Use country-specific review for campaigns. |
| Arabic multi-region | MENA markets vary by country, platform, and local partner. Treat Arabic-language exploitation as multi-territory unless a contract says otherwise. |

常見問題
- 每首發行都需要三種程式碼嗎？
- 理想情況下需要。發行商通常處理 UPC 和 ISRC；ISWC 需要你登記詞曲作品。
- 可以查詢已有程式碼嗎？
- ISWC 可透過 PRO 或相關資料音色庫查詢；UPC 和 ISRC 通常可在發行商後臺看到。
- 我的 beat 被取樣怎麼辦？
- 對方會產生新錄音和可能的新作品。你需要處理 sample clearance、署名和分成。
- Spotify 會分配這些程式碼嗎？
- 不會。它接收發行商和版權整理提供的資料。
