PINJAR MUSIC • MUSIC DISTRIBUTION GUIDE
Every release needs accurate information. Two small codes help identify your recording and the release it belongs to.
The simplest way to understand ISRC vs UPC is this: an ISRC identifies a specific recording, while a UPC identifies a release product, such as a single or album.
Knowing the difference helps you organise your catalogue, submit accurate metadata and avoid assigning unnecessary new codes to recordings that already have them.
1 What Is an ISRC Code?
ISRC stands for International Standard Recording Code. It identifies a particular sound recording or music video recording.
Think of it as a reference attached to the recording itself. The same song can have several different recordings, such as a studio performance and a separately recorded live performance.
Those recordings are different assets, even when their lyrics and melody are the same.
A song title is not a unique identifier
Different artists can release tracks with the same title. Keep the ISRC alongside the artist name, version and audio file so you can identify the correct recording.
IFPI explains that ISRC identifies recordings rather than the products that contain them. It does not identify the underlying composition.
2 What Is a UPC Code for Music?
UPC stands for Universal Product Code. In music distribution, a UPC is used to identify a release product.
That product might be a one-track single, an EP or an album containing several recordings. The individual recordings have their own ISRCs.
You may see the UPC described as a release barcode in your distributor’s dashboard. Keep it with your release-level information, including the release title and track list.
Check physical and digital requirements
If you also plan to sell CDs or other physical editions, confirm the identifier and barcode requirements with your distributor or manufacturer. Do not assume one setup covers every edition.
ISRC vs UPC: Key Differences
| Question | ISRC | UPC |
|---|---|---|
| What does it identify? | A specific recording. | A release product. |
| Where is it used? | Track-level recording information. | Release-level product information. |
| What about an album? | Each distinct recording has its own ISRC. | The album product has a UPC. |
| What if a single appears on an album? | The unchanged recording retains its ISRC. | The album is a separate product from the single. |
When reviewing a submission, check both levels. Correct track codes do not replace an accurate release title, artist credit or track order.
A Practical Example: From Single to Album
Imagine you release a song called “Evening Rain” as a single. The recording receives an ISRC, and the single release receives a UPC.
Later, you include the exact same recording on an album called “Letters Home.”
- The unchanged “Evening Rain” recording keeps its existing ISRC.
- New recordings on the album receive their own ISRCs.
- The album uses a different UPC from the previously released single.
The titles above are fictional examples. The important distinction is between reusing a recording and creating a new release product.

3 When Should You Reuse an ISRC?
An existing ISRC should stay with the same unchanged recording. IFPI advises against assigning another ISRC when that recording already has one.
Before submitting previously released audio, find the original identifier in your distributor account or catalogue records.
Changing Distributors
Tell your new distributor that the recording has already been released. Provide its existing ISRC and follow the distributor’s transfer instructions.
Ask separately whether the existing release UPC can be retained and what metadata must match.
Matching codes do not guarantee platform continuity
Do not assume an ISRC alone guarantees that stream counts, playlists or links will remain connected. Coordinate the transfer and verify the result on each platform.
4 When Might You Need a New ISRC?
A newly recorded performance or a different remix is a distinct recording. A separate music video recording also needs its own identifier, even when it contains the same audio recording.
Be Careful With Remasters
Not every technical change creates a new recording for ISRC purposes. IFPI’s guidance distinguishes routine processing from remastering that involves significant new creative input.
If your release involves an edit or remaster, describe the actual changes to your distributor and consult the official ISRC guidance before requesting a new code.
How Do You Get ISRC and UPC Codes?
Start by checking your distribution service. Providers may offer code assignment during submission and may allow you to enter identifiers you already have.
For ISRC assignment outside a distributor, consult IFPI’s official information about registration and authorised assignment routes.
Ask These Questions Before Uploading
- Are code assignments included in my plan?
- Can I enter existing ISRCs?
- How are existing release UPCs handled?
- When will the assigned codes be available?
- Can I export the identifiers for my records?
Identification is different from ownership
An ISRC does not establish rights ownership. Keep your recording agreements, permissions and contributor records alongside your catalogue information.
Keep a Simple Catalogue Record
A spreadsheet can help you find the right identifier when submitting an album, checking a statement or contacting support.
| Track-Level Records | Release-Level Records |
|---|---|
| Track title and version | Release title and format |
| Primary and featured artists | Release date and label name |
| ISRC | UPC |
| Final audio filename and duration | Track list and artwork filename |
| Contributor and ownership records | Distributor and platform links |
Format identifier columns as text in your spreadsheet so leading zeros are preserved. Copy codes carefully rather than retyping them from memory.
Keep the catalogue file with your final audio, artwork and release documents. Update it whenever a new release is approved.
Your Before-Upload Checklist
Confirm These Details
- I know whether each recording was previously released.
- I have checked for existing ISRCs.
- I have matched each code to the correct audio version.
- I have confirmed how the release UPC will be assigned.
- Artist names, titles and credits are accurate.
- I have saved the final audio and artwork.
- I have kept relevant agreements and permissions.
- I can access or export my catalogue identifiers.
Understanding ISRC vs UPC makes release administration easier. Keep recording identifiers and product identifiers organised, and resolve uncertain cases before submission.

Frequently Asked Questions
What is the main difference between ISRC and UPC?
ISRC identifies a particular recording. UPC identifies a release product that contains one or more recordings.
Does a one-song single need both codes?
In a typical digital distribution submission, the recording has an ISRC and the single release has a UPC. Your distributor can explain its assignment process.
Can I use one ISRC for every song on an album?
No. Each distinct recording needs its own identifier. Do not apply one track’s ISRC to other recordings.
Should I get a new ISRC when changing distributors?
The same unchanged recording should retain its existing ISRC. Give the code to your new distributor and follow its transfer process.
Does an ISRC prove I own a recording?
No. An ISRC identifies a recording and does not itself establish ownership. Keep the documents that support your rights.
Does every remaster need a new ISRC?
No. The nature of the changes matters. Consult IFPI’s guidance and your distributor when deciding whether a remaster requires a new identifier.
