IPI and IPN Numbers: Names, Performers and Royalty Matching
By Qlero Team

Distinguish IPI Base and Name Numbers from performer IPNs. Check writer names, co-writer records and correction routes without assuming an identifier proves payment.
IPI numbers help distinguish the people and companies involved in a work. But an identifier is not a payment instruction, and two numbers beside two names do not automatically mean royalties are going to the wrong person.
There is also an important terminology trap: an IPI Name Number and an International Performer Number (IPN) belong to different systems. This guide explains the distinction, preserves the difference between a person and their registered names, and gives writers and publishing teams a practical checking routine.
What IPI and IPN actually identify
IPI Base Number versus IPI Name Number
Interested Party Information (IPI) identifies people and legal entities with an interest in artistic works. Its scope is not limited to music. CISAC describes a unique Base Number allocated to each interested party, with names associated with that party. SUISA administers the system under CISAC and BIEM guidelines. CISAC's IPI overview explains this structure.
The Base Number identifies the party; an IPI Name Number identifies a registered name. SUISA describes the latter as an 11-digit number. Legal names, pseudonyms and name changes can produce multiple Name Numbers linked to one Base Number. That can be correct, not a duplicate-person error. SUISA also distinguishes the internally used Base Number from the Name Number used in public communication. See SUISA's explanation.
IPN means something different for performers
In SCAPR's International Performers Database, IPN means International Performer Number. It identifies a performer represented in that system; it is not another name for an IPI Name Number. SCAPR's authorised collective management organisations can create these performer records and numbers. A songwriter who also performs should not assume that one identifier substitutes for the other. SCAPR describes the IPD and IPN.
When exchanging data, write the identifier type out in full. A spreadsheet column labelled only “IPN” invites an avoidable misunderstanding.
Who assigns an IPI number, and where can you find it?
SUISA explains that an IPI number is allocated when a creator joins a collective management organisation. Its members can find their number in membership documentation, their portal, royalty statements or the works database. This is not a promise that every society completes an application within a particular number of days.
For BMI writers, Online Services and Songview provide ways to look up IPI/CAE numbers. BMI explicitly distinguishes an IPI/CAE number from its private account number: the account number is not the number to use for work registration. Check the instructions of the organisation receiving your data, rather than copying whichever number appears most prominently on an old statement. See BMI's account and IPI FAQs.
Why identifier problems deserve investigation—not a payment assumption
A useful diagnostic question is: “Does this registration identify the intended writer?” It is not: “Does this number prove the writer has been paid?” Treat identity, work registration and the resulting statement or payment as separate checks.
Registration routes also differ. The MLC's individual work-registration guide allows a writer search by name or IPI. Its bulk guide says a self-administered writer without a publisher IPI must use individual registration instead of the bulk route. A missing identifier therefore needs a route-specific response, not a blanket claim that no registration is possible. See individual registration and bulk registration requirements.
Do not infer the destination of money from a typo alone. The MLC gives too many IPI digits as an example of a visible bulk-validation error. A successful upload is a submission, not proof that the work has been accepted or royalties paid.
For an actual missing payment, gather the relevant work, registration reference, period and statement before asking the responsible organisation to investigate. This is a suggested investigation routine, not a finding about any particular royalty balance.
A worked example: Jennifer Marie Adams and “Jen Marie”
Consider a fictional songwriter, Jennifer Marie Adams, who later writes under the name “Jen Marie”. She finds a different IPI Name Number beside each name.
That observation alone does not establish a split identity. BMI, for example, explains that different registered names can have different IPI numbers while royalties still go to the same BMI account.
Jennifer's next step should be to ask her society to confirm which names and numbers belong to her, and whether the underlying party record is correct. She should also identify which name was used on the affected work registration. If a record is genuinely incorrect, she can request the appropriate correction and retain the case reference.
The example contains one fictional person and two names—not two proven payees, a verified loss or a promised recovery. Do not merge records or replace every identifier merely because the names differ. Check the evidence first, then follow the receiving organisation's correction process.
IPI numbers and co-writer credits
Suppose a work has three co-writers. A practical review is to check each writer's registered name, identifier and society against information they or their representative have confirmed. Keep agreement and share questions separate; counting three writers does not establish equal shares.
SUISA's instructions for a co-author who belongs to another society ask for that person's first name, surname, IPI number and society. They do not tell that co-author to join SUISA just to appear on the registration. The same guide says a pseudonym should already be registered with SUISA before it is used on a work registration. See SUISA's work-registration guidance.
For other destinations, check their current requirements. Avoid turning one society's form into a universal specification.
Four common problems to check
- A missing number. Confirm which identifier the receiving form requires and whether another documented registration route applies. Never invent a number to get past validation.
- Name variants whose relationship is unclear. Ask the relevant society to confirm the records. Multiple IPI Name Numbers are not, by themselves, evidence of an error.
- A mistyped or wrong-party number. Compare the number with its associated name, not just its length. Review validation messages and the resulting registration before concluding what happened.
- Outdated affiliation information. When representation changes, ask the relevant organisations what information and effective dates they need. Do not assume that changing a local contact record updates every society.
These are recommended checks, not statistics about how often writer payments fail.
Four practical controls before submission
- Confirm the identifier type and source. Record where the number was obtained, when it was checked and the name it belongs to. Keep a society's internal account number separate.
- Confirm name relationships. Resolve uncertainty with the society before requesting a merge or registering a supposedly new party.
- Review every co-writer entry. Check names and numbers together, then verify the submitted record and its status. Keep a submission receipt without treating it as payment evidence.
- Track corrections and affiliation changes. Keep the responsible organisation, case reference and confirmation together. Recheck the affected registration rather than assuming a correction propagated everywhere.
Some changes need direct assistance. The MLC's edit guide says changes to an existing writer's details or IPI number require contacting The MLC. A correction in your own database is not evidence that its work record has changed. See The MLC's editing instructions.
Where Qlero fits—and what to verify separately
Qlero documents payees as people or companies associated with accounts and contracts; statements and invoices are addressed to the payee. Accounts group balances and contracts hold deal terms. Those are accounting relationships, not proof that a society has validated a writer's IPI. See the payee glossary and payees versus accounts guide.
The glossary includes an optional payee external code. Qlero's artist documentation separately describes ledger reference codes as record-company-assigned references, often retained from older systems. Do not assume that either kind of local reference is an IPI, or that storing one checks it against an international registry. See ledger reference numbers.
These pages do not establish automatic IPI validation or synchronisation with society registrations. That documentation limit is not proof that a feature is absent. Ask Qlero to demonstrate the specific workflow you need; do not treat a local record update as confirmation of an external correction or money movement.
Frequently asked questions
Do I need a separate IPI for every performing rights organisation?
CISAC defines the Base Number around the interested party, not a new identity for each society. Name Numbers may differ. Ask the relevant societies to confirm your existing records when changing or adding representation rather than assuming you need a new identity.
What if I have two IPI numbers under different names?
First establish what the numbers represent. Different IPI Name Numbers can be legitimate. Ask your society to investigate if the names, party relationships or work registrations are wrong; do not request a merge solely because two numbers exist.
Does an incorrect IPI always cause rejection?
No single outcome should be assumed across systems. The MLC documents visible bulk-validation errors for some IPI problems. Check the receiving system's messages and the actual record; an upload receipt does not establish acceptance or payment.
Is IPI the same as ISNI?
No. IPI identifies interested parties within its rights-information system. ISNI identifies public identities of parties involved in creating, producing, managing or distributing creative content across fields. Neither description makes the identifiers interchangeable. See ISO 27729:2024's ISNI scope.
How can I check that my name variants belong to the same party?
Use your society's available records to identify the names and numbers, then ask it to confirm the underlying relationship if that is unclear. Retain its confirmation and review the affected work records. Public name lookups alone should not be treated as proof that every registration is correct.
Conclusion
Keep three questions separate: which person or company does this record identify, which registered name does the work use, and what does the responsible organisation actually confirm about the registration and payment? Clear identifiers help answer the first questions; they do not answer all three on their own.
