You registered your songs. You're signed up with ASCAP, BMI, or SESAC. You did the thing — so the royalties should be flowing, right?
Not necessarily.
PRO registration is one of those tasks that looks simple on the surface but has a dozen small details that, if you get any of them wrong, result in your money sitting in a holding account rather than landing in your bank. Some of these mistakes are obvious once you know they exist. Others are buried in the fine print of how collection societies actually process claims. All of them are fixable — but only if you know to look.
Here are the five most common PRO registration mistakes independent artists make, and what you can do about each one.
Mistake #1: Registering With the Wrong IPI Number (or No IPI at All)
Your IPI (Interested Party Information) number is how PROs and publishers identify you as a specific person across databases worldwide. It's a nine-digit number assigned when you join a PRO, and it travels with you everywhere — your song registrations, your publisher affiliations, your international sub-publishing agreements.
The mistake: A lot of artists don't know their IPI number when they register songs, so they leave that field blank or copy a number from a co-writer's profile by accident. Others register with a slightly different version of their legal name from what's on their PRO account, creating a mismatch that prevents the registration from connecting to their profile.
The fix: Log into your PRO's member portal and find your IPI number before registering anything. In ASCAP, it's on your member dashboard. In BMI, it's in your account settings under "profile." Once you have it, verify every song registration you've already made includes it accurately. If you find blanks or errors, you can usually update them directly in your PRO's portal — or contact member services to correct them.

Mistake #2: Missing Co-Writers From Your Registration
When you register a song, you're supposed to include every person who contributed to the songwriting — not just yourself. Every co-writer needs to be listed with their name, PRO affiliation, and their share of the composition.
This one happens in two ways. The first is that you forget someone entirely — maybe a hook writer, a topliner who contributed one verse, or a producer who co-wrote part of the melody. The second is more subtle: you list the co-writer, but they've also gone ahead and registered the same song independently — with different splits. Now the PRO has two registrations for the same song that disagree, and instead of paying anyone, they hold the money until it's resolved.
The fix: Before you register anything, get a signed split sheet that everyone agrees to. Registration conflicts between co-writers are one of the most common reasons royalties get held — and they're almost always preventable if you nail down the splits before anyone touches their PRO portal.
If you've already got conflicting registrations, you'll need to contact your PRO's member services and work through their dispute resolution process. It's slow, but it's solvable.
Mistake #3: Inconsistent Song Titles Across Platforms
Your PRO registration, your distributor metadata, your MLC registration, and your SoundExchange registration all need to reference the same song. The only way the matching systems know they're looking at the same work is the title, ISRC, and ISWC. If any of those don't line up, royalties get tagged as "unmatched" and sit in a holding account instead of flowing to you.
The mistake: You register "No Sleep (feat. Lena)" with ASCAP but distribute it to streaming platforms as "No Sleep." Or your registration has a comma where your metadata doesn't. Or the version you register is the radio edit and the one that's streaming is the original. Even tiny differences can break the matching process.
The fix: Standardize your song titles before you register anything, and use that exact title everywhere. Make sure the ISRC on your distributor's end matches what's in your PRO registration if applicable. And when in doubt, use ISWC codes to link your composition across databases — they're designed specifically to solve the cross-database matching problem.
The Mechanical Licensing Collective (MLC) is particularly dependent on accurate matching because they're responsible for paying out digital mechanical royalties from streaming. If your title or writer information doesn't match what the distributor submitted, your money goes into the unmatched pool. Here's how to claim it if it already has.
Mistake #4: Duplicate Registrations — When "Covering Your Bases" Backfires
This one catches a lot of artists who are trying to be thorough. You register your song with ASCAP. Then you find out there's also a publisher registration option, so you create a publishing entity and register it again — as both writer and publisher. Then your co-writer registers their share. Then a sync placement comes through and someone else registers a cue sheet for the same song. Now there are four or five records in the database that all reference the same work, and the PRO's processing systems are trying to reconcile them.
Duplicate registrations don't automatically cancel each other out. They create processing delays, potential splits disputes, and sometimes result in royalties being held indefinitely while the PRO sorts out which registration is authoritative.
The fix: Check your PRO's portal before you register anything to see if a record already exists for that song. Many PROs allow you to search your own catalog in the member portal. If you find duplicates, contact member services to merge or deactivate the extras — you don't want to just leave them there.
If you have a large catalog, this is one of the things a proper audit will catch systematically. It's hard to spot manually when you're looking at fifty or a hundred songs.
Mistake #5: Registering in the U.S. and Nowhere Else
Your PRO handles your domestic performance royalties — what gets collected when your song plays on radio, streaming, TV, or live venues inside the United States. But if your music is playing anywhere else in the world, those royalties are handled by international collection societies, and your U.S. PRO doesn't automatically collect all of it for you.
The major U.S. PROs have reciprocal agreements with most international societies, which means they theoretically forward international royalties back to you. In practice, those agreements have gaps, the processing can take two to three years to complete, and certain territories — especially emerging markets in Africa, Southeast Asia, and Latin America — have limited reciprocal coverage.
The mistake: Assuming your U.S. PRO registration covers everything. If your catalog is getting significant plays internationally — especially on playlist-driven platforms that reach global audiences — there may be territories where royalties are generated but never collected on your behalf.
The fix: For most independent artists with modest international streaming numbers, your PRO's reciprocal arrangements will cover the bulk of what you're owed. But if international markets are a meaningful part of your audience, it's worth understanding which territories your PRO has agreements with and which it doesn't. Collecting international royalties properly sometimes requires working with a publishing administrator who has direct affiliations in specific territories.
What to Do If You've Made Any of These Mistakes
The good news: all of these mistakes are retroactive problems, not permanent ones. Royalties don't disappear when your registration is wrong — they accumulate in holding accounts, sometimes for years, waiting for you to claim them. The money is often still there; you just need to fix the registration to get it flowing.
Start with a registration audit. Pull every song in your catalog and cross-reference it against your PRO portal, the MLC's database, and SoundExchange (if you're a recording artist or featured performer). Use the PRO, MLC & SoundExchange registration checklist to work through it systematically.
For artists with larger catalogs — say, twenty or more songs, or a few years' worth of releases — doing this manually can take days, and it's easy to miss things when you're the one who made the mistakes in the first place. This is exactly what a professional catalogue audit is built for. An auditor looks at your entire catalog across every database, flags every error, conflicting registration, or unmatched royalty, and tells you exactly what to fix and what to claim.
If you're curious whether your catalog has issues worth looking at, our catalogue audit service starts at $497 and includes a full cross-database review. For artists who discover meaningful uncollected royalties, it typically pays for itself many times over.
