ISRC and UPC Codes Explained for Independent Artists
- 31 Oct 2026

Every song on a streaming platform carries two identifiers behind the scenes: an ISRC for the recording and a UPC for the release it belongs to. They decide how stores match your music, track your streams and pay your royalties. Here is what each code does and how to handle them.
What is an ISRC?
The International Standard Recording Code (ISRC) is a 12-character code that identifies one specific recording. A typical ISRC looks like GB-XXX-26-00001, usually written without the dashes. Each recording gets its own ISRC, and that code stays with the recording wherever it is released.
Platforms use the ISRC to count streams, connect the recording to royalty reports and recognise the same track across different releases. If your single later appears on an EP or album, using the same ISRC keeps its play count and history together.
When you need a new ISRC
- A new song.
- A different version of a song, such as a remix, acoustic version, radio edit, instrumental or sped-up version.
- A remaster that changes the audio.
If the audio is exactly the same, keep the same ISRC, even when the song appears on a new release.
What is a UPC?
The Universal Product Code (UPC) is a 12- or 13-digit barcode number that identifies a whole release: a single, an EP or an album. Stores use it to group the tracks, artwork and release details into one product. Every new release needs its own UPC.
How to get ISRC and UPC codes with SpaceMedia
You do not need to buy codes before you start. When you create a release in SpaceMedia you can leave the ISRC field empty and choose automatic assignment, and you can enable automatic UPC generation for the release. If you already own codes, for example from a previous distributor, enter them instead.
Why reusing codes matters when you switch distributors
If you move a release from another distributor, submit it with the same UPC and ISRCs, plus the same artist name, titles, audio and artwork. This helps stores match the new delivery to the existing release and keep its stream history. Our guide on switching distributors walks through the full process.
Quick checklist
- One ISRC per unique recording, kept for life.
- One UPC per release.
- Never reuse an ISRC for a different version of a song.
- Keep a spreadsheet of your codes, titles and release dates.

SpaceMedia delivers music to a broad and changing network of streaming, download, social, and music-identification platforms. This can include major services such as Spotify, Apple Music, iTunes, YouTube Music, Amazon Music, Deezer, TikTok, Facebook and Instagram, SoundCloud, Tidal, Pandora, Boomplay, Anghami, iHeart, JioSaavn, KKBOX, NetEase Cloud Music, Tencent, Qobuz, and other supported partners.
The exact network can change as platforms update territories, rules, and delivery requirements. SpaceMedia gives you access to supported distribution channels, but no distributor can guarantee that every platform will accept every release in every country.
Most major streaming services do not let every artist upload music directly. A distributor like SpaceMedia delivers your audio, artwork, metadata, and rights information to supported platforms so your release can appear on services such as Spotify, Apple Music, YouTube Music, Amazon Music, Deezer, TikTok, and others.
Create an account, choose the plan that fits your needs, upload the final release files, review the details, and submit. SpaceMedia reviews Free submissions within 5 business days, Premium submissions within 2 business days, and Label submissions within 1 to 2 business days. Store publishing happens afterwards.
You can monetize eligible music on supported video platforms through Content ID when your plan includes it. Content ID is currently included with Premium and Label, and it is not included with the Free plan.
Only submit music you fully control for Content ID. Tracks with uncleared samples, non-exclusive beats, royalty-free loops used by many creators, public-domain recordings, or disputed rights may be rejected or may cause claims that need to be resolved.
Submit your release through SpaceMedia and choose distribution to social music platforms where available. Eligible releases can be delivered to platforms such as TikTok, Facebook, Instagram, and other supported social or short-form music services.
Once delivered, each platform decides how the music appears, how long processing takes, and which features are available in each territory. Use accurate metadata and clean audio to reduce avoidable delivery issues.
Independent music distribution lets artists release music to streaming, download, and social platforms without signing to a traditional record label. You stay in control of your music while using a distributor to deliver it to supported services.
With SpaceMedia, you can manage releases, artist details, earnings, and payout information from your account. All standard plans let users keep 100% of standard DSP royalties.
The Free plan lets artists release music without an upfront distribution fee and keep 100% of standard DSP royalties.
This gives new artists a way to start releasing music before paying for a yearly plan. Premium and Label add more primary-artist capacity and tools. All standard plans include 100% of standard DSP royalties.
Yes. In many cases you can transfer existing releases to SpaceMedia while keeping them live, as long as you submit the same metadata, audio, artwork, UPC, and ISRCs where available.
Keep the old release live until the SpaceMedia delivery is live and matched correctly. Removing the old version too early can interrupt availability or make stores treat the transfer as a new release instead of matching it to the existing one.
