ISO 20022 Data Source Schemes
1- DESCRIPTION
The ISO 20022 Data Source Scheme (DSS) is a mechanism that allows an institution or market
organization to specify and use a proprietary code set that is not owned nor managed by ISO 20022,
and that replaces a standard code set (either a specific ISO 20022 managed code set or another ISO
standard code set, e.g. BICs or ISINs) in specific Message Components where the use of DSSs has
been approved.
This document describes the DSS concept and registration process and list the DSSs already defined
for use in ISO 20022 messages.
The DSS mechanism was first introduced in ISO 15022 – Securities – Scheme for messages.
The ISO 20022 DSS consists of the following parts:
 a mandatory 'data source issuer' that identifies the institution or organization issuing the proprietary
code set (known as the ‘data source issuer code’ in the ISO 15022 DSS).
 an optional 'data source scheme name' that identifies the code set in case a single data source
issuer issues more than one code set for the same business purpose, e.g., two code schemes for
identification of parties (known as the ‘data source issuer sub-code’ in the ISO 15022 DSS).
 the actual code value.
The below table compares the DSS concepts in ISO 15022 and ISO 20022:
ISO 15022 concepts
ISO 20022 concepts
Context is specified by the
generic field
Example: Field 95R - Party
Context is specified by the
lowest MessageComponent
Example:
GenericIdentification20 used
for Proprietary Reason codes
Data source issuer
Data source scheme name
Data source issuer code
Data source issuer subcode
Data Field that contains
the code value
A separate MessageElement
that contains the code value

2- Registration Process
The approval of an ISO 20022 DSS requires agreement at two levels:
The Message Definition must include the possibility to use a DSS by including the appropriate structure
in the required place. This is agreed by the SEG at the time the Message Definition is approved (initial
submission or maintenance).
Specific code sets must be registered for use in the specific places where it has been agreed that a DSS
can be used. This registration may be obtained at the time the Message Definition is approved or later sometimes much later - namely any moment after the Message Definition has been approved.
Approval of the possibility to use DSSs in a new Message Definition
When a submitting organization is convinced of the need for a Data Source Scheme (existing or new
DSS) in a specific context, it will include the appropriate structure in the candidate ISO 20022 messages.
During the message evaluation, the assigned SEG will verify the business case to accept use of nonstandard code sets. Similarly, if the need arises later to introduce the possibility to use a DSS in an
existing message, a change request to update the structure of the Message Definition will be submitted
to the relevant SEG for approval.
Registration of (additional) DSSs for use in existing Message
Definitions
The RA maintains the list of all ISO 20022 Data Source Schemes as well as the specific Message
Components in which they can be used.
If an institution or market organization requires the use of a new proprietary code set, it will send a
request for registration of a new DSS to the RA, using the specific DSS template. The RA will validate
the request, assign a new DSS (issuer and scheme name(s)), inform the requestor and publish the new
DSS information in an updated version of this document.
In case of conflict, the final decision will be taken by the RMG.

The list of current ISO 20022 DSSs is published below and gives the following information:
which ISO 20022 Message Components support which DSSs
the data source issuer information: description, country of issuer
the data source scheme name(s), if any.

3- LIST OF DATA SOURCE SCHEMES
Requests for additional Data Source Schemes or use of existing Data Source Schemes in new Message
Components must be submitted to the ISO 20022 Registration Authority using the official template for
'Request for ISO 20022 Data Source Scheme Registration' (www.iso20022.org).
In case of questions, please contact the ISO 20022 Registration Authority at iso20022ra@iso20022.org
