How do you get an ISIN code?
To get an ISIN code, you must apply to the National Numbering Agency responsible for the jurisdiction where your financial instrument is issued.
The process usually involves preparing issuer documents, describing the financial instrument, submitting the application, and waiting for validation and assignment of the ISIN code.

Step 1: identify the correct National Numbering Agency
The first step is to determine which National Numbering Agency should handle your application.
This depends on:
- The issuer’s country of incorporation
- The type of financial instrument
- The primary trading market
- The jurisdiction of issuance
Each country has its own competent agency. For example, Euroclear France handles French securities, while other jurisdictions have their own assigning organizations.
Step 2: prepare the required documents
Application quality is one of the main factors affecting processing time.
You typically need:
Entity documents
- Certificate of incorporation
- Articles of association
- Proof of registered address
- Authorized representative details
- LEI if available or required
Instrument documents
- Prospectus or term sheet
- Instrument type
- Currency
- Nominal value
- Issue date
- Maturity date if applicable
- Coupon or interest rate if applicable

Step 3: submit the ISIN application
Once the documents are ready, the application is submitted to the relevant agency.
Submission may be done through:
- Online portal
- Professional intermediary
- Agency-specific process
The information must be complete, consistent and accurate. Errors can lead to delays, additional questions or rejection.
Step 4: review and processing
The agency reviews the application to confirm:
- The instrument is eligible
- The documentation is complete
- No ISIN already exists for the same instrument
- The instrument details are correctly described
This stage can take from a few days to several weeks depending on the country, agency and complexity of the application.

Step 5: ISIN assignment
Once the application is approved, the agency assigns the ISIN code.
The code is then communicated to the applicant and can be used to:
- Identify the instrument
- Support settlement and clearing
- Meet regulatory reporting requirements
- Enable trading or reporting
Common mistakes to avoid
The most frequent mistakes are:
- Incomplete documentation
- Wrong agency selection
- Inconsistent information
- Insufficient instrument description
- Missing LEI when required
- Applying too late
