I am a SEC Party; how do I check my ID Allocation, Signifier and MPID details?

SEC Parties can log in and visit the ID Allocation webpage to download the latest version of the ID Allocation Spreadsheet:

• ID Allocation Spreadsheet – Latest Version
• ID Allocation Spreadsheet – Latest Version Alternative Format

This spreadsheet contains the SEC Party name, Signifier, Organisation Number and ID Allocation range for all current and former Parties. It also contains the Market Participant Identifier (MPID) information associated with each Party. If your Party name or MPID information needs to be updated, please use the online Change in Party Details form.

For more information, please find the ID Allocation Procedure Guidance Notes.
