What is a P line and a C line?

The (P) line names who owns the sound recording and the year it was first released; the (C) line names who owns the copyright in other works on the release, usually the artwork. What each one means, how to write them, and the mistakes we see most. Sources checked on 27 Oct 2026.

Key facts

  • DDEX says the ℗ notice signifies that rights exist in a sound recording (a phonogram) and names the current owner of the masters.
  • The ℗ year is the year the recording was first released anywhere in the world, not a re-release year, per DDEX guidance.
  • The © notice covers other works such as cover artwork and printed material, and sometimes the composition and lyrics.
  • In the US, copyright notice has been optional for works published on or after 1 March 1989, per the US Copyright Office.

A P line (℗, for "phonogram") is the line in a release's metadata that names who owns the sound recording and the year it was first released; a C line (©) names who owns the copyright in the other creative works on the release, most often the cover artwork. Most distributor upload forms ask for both, and in our experience many independent artists fill them in with a guess.

They sit in the same place as your ISRC and the rest of your release metadata, and they only make sense once you know that every song carries two copyrights: one in the composition, one in the recording.

The P line: the recording

DDEX, the body that sets the standard formats labels and distributors use to send releases to stores, says the purpose of a ℗ notice is "to signify that rights exist in a sound recording" and to identify the owner of those rights, according to its PLine and CLine guidance.

Two parts matter:

  • Year: the year the recording was first released anywhere in the world, not the year of a re-release or a new pressing (DDEX).
  • Owner: the current owner of the original recording, the master. DDEX recommends the full corporate name rather than an imprint or division name, and lets a licensee appear only after the owner, as in "℗ 2007 XYZ Record Company Limited, under exclusive licence to…".

If you recorded and paid for the track yourself and signed nothing away, that owner is you, or your company if you release through one.

The C line: everything else

The © notice covers copyright in other works: cover artwork, inlays and other printed material, artwork on websites, and sometimes the composition and lyrics, says the same DDEX page. Its year is the year that work was first published.

DDEX advises separate notices even when one company owns both, because the two refer to different rights. Where the symbols can't be typed, it says to write "(P)" and "(C)".

Do you legally need them?

In the US, no. The US Copyright Office says notice was mandatory on published phonorecords before 1 March 1989 and has been optional for works published on or after that date; sound recordings are protected automatically once fixed. DDEX likewise treats both notices as optional in its release messages. Stores and distributors may still require the fields on their forms.

What we think

Treat the P line as a public ownership claim, not a box to clear the upload. It is the one line on a streaming page that says who owns the master, and it travels with the release to every store. Three habits save trouble later:

  1. Put the original year, always. A remaster or a re-upload through a new distributor keeps the first-release year. Changing it muddies the record of when your recording entered the world.
  2. Don't put your distributor in it. A distributor that only delivers your files does not own your recording; naming it in the P line hints otherwise. If a label really does own or license the master, the contract decides the wording, not the upload form.
  3. Clear the art before you claim it. The C line asserts ownership of the cover. If a designer or photographer made it, get the rights in writing first; a C line can't create rights you don't hold.

Our reading: the P line is the cheapest piece of rights hygiene a self-releasing artist has. It costs nothing, it is copied to every store, and when a dispute or a buyout offer comes, it is the first place anyone looks.

For the identifier that pairs with it, see what an ISRC is.
