An International Standard Recording Code (ISRC) is the global identifier for one specific sound recording. If you record the same song twice, each version needs a different ISRC. If you re-release the exact same audio, the original ISRC stays the same.

It works as the recording’s permanent ID across digital service providers (DSPs), distributors, rights organizations, and royalty systems. That is how platforms track the correct recording, match metadata, and route usage and payment data more accurately. The ISRC Database contains over 150 million unique ISRCs.

What is an ISRC in music?

An ISRC is a 12-character global code used to identify a specific sound recording or music video. It helps distinguish one recording from another, even if the underlying song is the same.

Each version of a track, such as a live recording, remix, or remaster, receives its own unique ISRC. Once assigned, the code stays with that recording across platforms, distributors, and ownership changes, as long as the audio remains unchanged. This allows systems to consistently match the recording across:

• Distribution systems
• Metadata databases
• Usage and streaming reports
• Royalty tracking systems

That is how platforms connect streams, usage data, and payments to the correct recording. A standard ISRC follows a structured format. For example: ISRC AA-6QZ-20-00047

Each part defines how the recording is identified:

• Prefix code (AA-6QZ)
• Two letters followed by three alphanumeric characters
• Identifies the registrant (artist, label, or distributor), assigning the ISRC
• Assigned by a national ISRC agency and cannot be changed once issued
• In the United States, prefixes may begin with US, QM, QZ, or QT
• Year of reference (20)
• The last two digits of the year the ISRC is assigned
• May differ from the actual recording year
• Resets the available code range each year to prevent duplication
• Designation code (00047)
• A five-digit numeric code unique to the recording within that prefix and year
• Must not be repeated within the same assignment cycle
• Ensures each recording has a distinct identity

This structure combines registrant identity, assignment timing, and recording-level numbering to create a globally unique identifier for every recording.

The key distinction is:

• ISRC identifies the recording
• UPC or EAN identifies the release
• ISWC identifies the composition

How ISRCs Work?

ISRC works by giving each recording one fixed identity that stays with it across the music ecosystem. Once assigned, the same ISRC remains attached to that recording across distributors, platforms, and reporting systems.

Here is the workflow:

• ISRC is assigned during distribution: When a track is prepared for release, the ISRC is included in the metadata sent to digital service providers and partners.
• ISRC is tied to the recording, not the release: The same recording can appear across singles, albums, or compilations while keeping the same ISRC, as long as the audio does not change.
• Platforms use ISRC to identify the track
  Once live, the ISRC appears in platform metadata, reporting files, and licensing systems. It helps services recognize the correct recording across catalogs.
• Usage tracking is done through reports
  ISRC does not collect royalties directly. Instead, it helps systems match streams, downloads, and other usage data to the correct recording.
• Royalty systems rely on ISRC for accuracy
  When the ISRC is linked to ownership and rights data, it improves how royalties are calculated and routed across different stakeholders.
• Consistency ensures reliable reporting
  Using the same ISRC for the same recording avoids duplication, while assigning a new ISRC for changed audio ensures each version is tracked separately.

What happens if you don’t have an ISRC?

If you do not have an ISRC, your track may not move correctly through distribution and monetization systems. Most commercial workflows require an ISRC before a recording can be delivered to platforms and tracked for royalties. This impacts both release execution and earnings accuracy.

Without an ISRC, 

• Your track may not be accepted or processed correctly by stores and streaming platforms
• Royalty tracking becomes less reliable across systems
• Switching distributors later becomes more complex
• Streams and usage data can be split across duplicate or mismatched versions

The fix is simple. You can assign an ISRC even after your track has already been released without one. That means, you can add an ISRC before re-releasing the track so it can be tracked and distributed properly going forward.

How to get an ISRC?

You can get an ISRC in two ways: through a distributor or by assigning your own using an official agency. Most first-time distributors choose the distributor route because it is faster and requires no setup.

Option 1: Get an ISRC through your distributor

This is the simplest method if your goal is to release music instead of managing code yourself. Many distributors, including SoundCloud, assign an ISRC during upload if you do not already have one.

Steps:

1. Upload your track
2. Enter track metadata (title, artist name, contributors)
3. Add your existing ISRC or let the distributor assign one
4. Submit for distribution or monetization

This route works for artists releasing music regularly without needing to manage their own catalog system.

Option 2: Get your own ISRC prefix

This approach is used by labels or artists managing a large catalog over time. You apply through an official national ISRC agency to get a prefix, which allows you to assign ISRCs yourself.

You can apply through agencies such as:

• U.S. ISRC Agency
• PPL (United Kingdom)
• GEMA (Germany)
• SACEM (France)
• ARIA (Australia)

Each country has its own designated ISRC manager under the International Federation of the Phonographic Industry (IFPI) system.

Here are the steps to apply:

1. Apply for an ISRC prefix through your national agency
2. Receive your assigned prefix
3. Create unique ISRCs for each recording
4. Use those ISRCs when distributing your music

Use this option if you want:

• full control over ISRC assignment
• a consistent internal catalog system
• the ability to manage many releases independently

Do you need a new ISRC for every release?

No. You need a new ISRC only when the recording changes, not when the release format changes. The rule is simple: one ISRC = one recording.

Use the same ISRC when:

• The same recording appears on a single, EP, album, or compilation with no audio changes
• You move the same recording to a new distributor
• You re-release the same audio in another territory or store setup

Use a new ISRC when:

• You release a remix or a live version
• You edit or change the audio
• You release a new remastered version, treated as a different recording

Thus, reusing an ISRC for a different recording creates metadata confusion. Likewise, assigning a new ISRC to unchanged audio can split streams and reporting.

How ISRCs track your royalties across platforms

ISRC does not collect royalties, but it is the core identifier that helps systems recognize the correct recording. It connects your track to streaming data, usage reports, and payment systems across platforms.

This is how ISRC is used operationally:

• Distributors include ISRCs in delivery feeds to platforms
• Digital service providers use ISRCs in usage and stream reporting
• SoundExchange uses ISRCs to track digital performance royalties 
• Royalty systems match ISRCs with ownership metadata to route payments accurately

ISRC is only one part of the royalty system. Different organizations handle different income streams:

• American Society of Composers, Authors and Publishers (ASCAP) collects performance royalties for songwriters. It represents more than 1.1 million songwriters, composers, lyricists, and music publishers.
• Broadcast Music, Inc. (BMI) also collects performance royalties for songwriters. It supports more than 1.4 million songwriters, composers, and publishers, and over 25 million musical works.
• Mechanical Licensing Collective collects mechanical royalties from eligible U.S. streams and downloads. It added 11+ million songs to its database in 2024.
• SoundExchange distributes digital performance royalties. It has paid out over $13 billion in digital performance royalties to date on behalf of more than 800,000 music creators.

Thus, the takeaway is simple. ISRC gives your recording a clear identity. Without it, platforms and royalty systems have a harder time matching your track correctly, which weakens tracking and payment accuracy.

How ISRCs power music metadata & discovery

ISRC does not directly improve rankings or push a track into more recommendations. What it does is help platforms identify the correct recording within the metadata system. That leads to cleaner catalog management, fewer mismatches, and more reliable track matching across services.

This matters for discovery in practical ways:

• The correct recording is linked to the right artist profile
• Catalog moves are easier to match across platforms
• Duplicate versions are less likely to appear
• Platform systems can process metadata more accurately when all details match

Having an ISRC assigned to each recording helps when you switch distributors. It gives platforms a consistent way to identify the same track and reduces the risk of broken metadata, duplicate versions, or lost stream history.

How does SoundCloud help you distribute music with ISRCs?

SoundCloud simplifies ISRC handling by combining upload, metadata, and distribution in one workflow. Each track requires standard metadata, including title, main artist, contributors, and ISRC, and SoundCloud can assign an ISRC if you do not already have one.

For first-time distributors, the challenge is not understanding ISRC in theory. It is managing metadata correctly while releasing on time. SoundCloud reduces that friction by handling ISRC assignment and distribution together.

SoundCloud’s Artist Pro includes distribution to Spotify, Apple Music, TikTok, and 50+ platforms, with artists keeping 100% of royalties. It is priced at $99 per year.

What this enables:

• Upload and manage release metadata in one place
• Get ISRC assigned during the same workflow
• Distribute to major streaming platforms
• Track audience and earnings in a single dashboard
• Move from upload to monetization without separate tools

Common ISRC mistakes artists make

Most ISRC issues come from mixing up recording changes, release changes, and metadata. The rule is simple: one ISRC belongs to one recording, and it should stay consistent across platforms.

Common mistakes to avoid:

• Assigning a new ISRC to the same audio, which can split streams, and reporting
• Reusing an ISRC for a different version, such as a remix or live recording
• Confusing ISRC with UPC or EAN, where ISRC is for the track and UPC identifies the release
• Using inconsistent metadata (titles, artist names, contributors), which breaks matching
• Not saving your ISRCs makes distributor switches harder
• Assuming ISRC alone handles royalties without proper registrations

Final thoughts

ISRC may seem technical at first, but it becomes straightforward once you understand how it connects your recording to distribution, metadata, and royalties. By using the same ISRC for the same recording, assigning a new one only when the audio changes, and keeping your metadata consistent, you can avoid common release and tracking issues.

SoundCloud makes this process easier by handling ISRC, metadata, and distribution in one workflow. Instead of managing multiple tools, you can release music correctly and track your earnings without added complexity.

If you are ready to simplify your release process and stay in control of your catalog, SoundCloud Artist Pro gives you the tools to do it in one place.
