ISRC and UPC codes are identifiers used to organize music releases across digital stores, streaming services, reporting systems and other parts of the music supply chain. An ISRC identifies one specific sound recording, while a UPC identifies the release or product that contains recordings, such as a single, EP or album. They help match metadata and usage data, but they do not prove copyright ownership or guarantee royalties.
What is the difference between an ISRC and a UPC code?
An ISRC is for an individual recording; a UPC is for the overall release. If you put out a three-track EP, each track recording needs its own ISRC, while the EP as a product generally uses one UPC. Thinking of a release as a container makes the distinction easier: the UPC labels the container, and ISRCs label the recordings inside it.
Both codes are important because music platforms and industry systems need stable ways to distinguish releases that may have similar artist names or track titles. A song called “Home” by one artist is not the same recording as “Home” by another artist—and a live version is not automatically the same recording as a studio version.
ISRC: the identifier for a sound recording
ISRC stands for International Standard Recording Code. It is attached to a particular audio recording and remains associated with that recording wherever it is delivered, provided the recording itself has not materially changed.
For example, an artist may release:
- “Midnight Drive” (original studio recording)
- “Midnight Drive” (acoustic version)
- “Midnight Drive” (live recording)
- “Midnight Drive” (remix)
These are separate recordings, so they ordinarily need separate ISRCs. The title can be similar or even identical; what matters is whether the underlying recorded audio is the same.
UPC: the identifier for a release product
UPC stands for Universal Product Code. In music distribution, it is commonly used to identify the release as a whole: a single, EP, album, compilation or another release package. You may also hear it called an EAN in some regions and systems. The exact barcode format can vary, but the practical task is the same: identify the product-level release.
If your debut single later appears on an album, the single and the album are different release products. The original recording can often retain its ISRC, while the album as a new product generally has its own UPC. This is one reason artists should keep a clean record of identifiers from every release.
Why do independent artists need ISRC and UPC codes?
You need accurate identifiers to give each recording and release a consistent identity in distribution and reporting workflows. They help distinguish your work from similarly named content and support cleaner metadata when your music is delivered to multiple services.
For an independent artist, the most useful reason to understand these codes is practical: you will make better decisions when you re-release a track, move to a new distributor, issue an expanded edition, or add an existing single to an album.
However, identifiers do not replace rights administration. An ISRC does not register a composition, grant permission to use a sample, clear a cover song, or establish who owns master rights. A UPC does not do those things either. Keep your agreements, splits, permissions and source files in order separately.
When should you keep an existing ISRC?
Keep the existing ISRC when you are distributing the exact same sound recording again. This is often relevant when a track is being moved to a different distribution service or included in a later release such as an album, subject to the receiving services’ and distribution workflow requirements.
Using the existing identifier for the same recording can help maintain continuity between records associated with that recording. Before submitting a release, verify the code directly from your prior release records rather than copying it from an unverified source or relying on memory.
Situations where the recording may need a new ISRC
A new ISRC is commonly appropriate when the audio recording is genuinely different. Examples can include:
- A new studio version or re-recording
- A remix with changed recorded audio
- An acoustic, instrumental or live version
- A remaster that has been materially altered
- A version with a different featured artist performance
- A shortened, extended or otherwise edited recording where the delivered audio differs
There can be edge cases, especially for remasters, edits and archival projects. If you are uncertain, review the instructions in your distribution workflow and preserve documentation showing what version was delivered. Do not assign an old ISRC simply because the song title and composition are the same.
When do you need a new UPC?
A new UPC is generally used for a distinct release product. A deluxe edition, an album, a separate single release and a compilation are different packages, even if some recordings overlap. That means each release product should be treated carefully in your metadata planning.
Consider this common release sequence:
- You release one track as a single.
- Later, you release an EP containing that same track plus additional songs.
- Later still, you publish an expanded version of the EP with bonus recordings.
The original track may retain its ISRC if its audio is unchanged. But the single, original EP and expanded EP are separate products, so each is normally handled as a distinct release with its own product-level identifier.
Who provides ISRC and UPC codes?
Artists commonly receive or enter these identifiers during the distribution process, depending on the service and the release workflow. Some artists also obtain and manage identifiers through their own established systems. Whichever route you use, the key is to avoid creating conflicting records for the same audio.
Before submitting, check whether you already have valid ISRCs and a UPC from an earlier release. If you do, keep a copy of the original metadata and confirm that the audio and release details match your intended submission. If you do not, follow the options and fields provided by your chosen distributor.
AIDistroMusic’s music distribution service is a practical starting point for artists preparing a release for digital platforms. Distribution through AIDistroMusic is free for artists. The important work still begins before submission: naming files clearly, finalizing credits and deciding whether your track is truly a new recording or an existing one.
ISRC and UPC release-preparation checklist
Complete this checklist before you upload a single, EP or album. It reduces avoidable metadata confusion and gives you a useful archive for future releases.
- Confirm the audio version: Label it accurately as original, live, acoustic, remix, instrumental, radio edit or another applicable version.
- Create a release inventory: List every track, its version name, featured artists and whether it is new or previously released.
- Collect existing ISRCs: For unchanged recordings already released, retrieve the codes from reliable prior release records.
- Plan the product: Decide whether you are delivering a single, EP, album, compilation or expanded edition. This determines the product-level release structure.
- Check titles and artist credits: Keep spelling, punctuation and featured-artist formatting consistent across audio files, artwork and metadata.
- Keep a master metadata sheet: Store track titles, versions, writers, performers, release date, ISRCs, UPCs and artwork version in one secure place.
- Review rights before delivery: Confirm that you have the rights and permissions needed for the audio, artwork, samples and any third-party material.
- Archive submitted files: Save the exact audio masters, cover art and final release information used for the submission.
This preparation is valuable long after release day. If you later need to deliver the same recording in another context, correct metadata is easier to preserve when you can locate the original master and identifier immediately.
Common ISRC and UPC mistakes to avoid
The most common mistake is treating a song title as if it identifies a recording. A title identifies a work only informally; it cannot tell a platform whether the audio is a first release, remix, re-recording or live performance.
- Assigning one ISRC to multiple different versions of a song
- Creating a fresh ISRC for the exact same previously released audio without checking first
- Using a single’s UPC for a later album or EP product
- Entering inconsistent artist names, track titles or version labels
- Confusing the composition with the sound recording
- Assuming an identifier clears samples, covers or other rights
- Failing to retain a copy of prior release metadata when changing distribution arrangements
A simple rule helps: first ask, “Is this the identical audio recording?” Then ask, “Is this the same release product?” Your answers point toward the correct ISRC and UPC treatment.
How cover songs affect your release metadata
A cover recording is a new sound recording, even though it uses a composition written by someone else. It needs careful metadata and rights preparation. The recording identifier does not by itself authorize use of the composition.
For artists using AIDistroMusic, cover-song licensing costs USD 10. You do not have to pay that fee upfront: it is deducted later from royalties only if the release has successfully reached music platforms. Learn more about the workflow on the cover song distribution page. Licensing and rights obligations can depend on the territory, the composition and how the recording is used, so this is not a substitute for advice tailored to your situation.
What about ISRCs for AI-generated or AI-assisted music?
AI-generated or AI-assisted music still needs clear, accurate release metadata when submitted for distribution. Treat each distinct delivered recording as its own recording for identification purposes, and ensure your artist name, version information and rights information are truthful.
Music created with AI may be distributed through AIDistroMusic. Individual streaming and download platforms may, however, refuse distribution, availability or later monetization of AI-generated or AI-assisted music under their own policies and discretion. Read the AI music distribution guidance before planning a release, and do not assume a code alone makes any recording eligible at every platform.
A simple workflow for your next release
- Lock the master: Decide which exact audio version you will release and stop making untracked changes.
- Identify the release type: Define the product as a single, EP, album or another package.
- Audit prior releases: Determine whether any track is an unchanged recording that already has an ISRC.
- Prepare metadata: Finalize titles, versions, artist credits, contributor information and artwork details.
- Review rights: Address cover songs, samples, collaborations and artwork permissions before delivery.
- Submit carefully: Use the distributor’s release fields consistently and retain a copy of the final information.
- Maintain your archive: Add the confirmed identifiers and delivered files to your master metadata sheet.

Frequently asked questions
Does every track on an album need an ISRC?
Yes, each distinct sound recording on an album should have its own ISRC. An album-level UPC identifies the release product as a whole.
Can the same ISRC appear on a single and an album?
It can when the audio recording is exactly the same. The single and album are separate release products, so they are generally associated with different UPCs.
Does an ISRC prove that I own a song?
No. An ISRC identifies a recording; it does not prove ownership, register copyright, or resolve disputes over rights.
Do I need a new ISRC for a remix or live version?
Usually, yes. A remix or live version is typically a different sound recording from the original studio recording.
Can I use ISRC and UPC codes to clear a cover song?
No. Codes identify the recording and release. Cover-song permissions and licensing are separate rights matters.
