Saxo uses many different “numbers” to identify and classify client account data. Below is an explanation of the different numbers used, how they are used and the associated terminology.
Client ID, also called counterpart ID: These names are used interchangeably. The closest equivalent of this number at Binck is the BinckAccountNumber. The client ID (counterpart ID) is the unique identifier for a specific client account. You should always mention the client ID when raising a case with Saxo or when speaking with our support teams and referring to a client.
Please note: An individual person can have multiple client IDs (counterpart IDs) for multiple accounts. Saxo only allows one self-directed trading account (i.e. the client actively trading the account him/herself) but multiple accounts if the additional accounts are not managed by the client him/herself (and instead are managed by different IAMs).
The client ID (counterpart ID) is visible in SaxoPartnerConnect in the client tree, as well as on the top right and within the client details:
Account ID for sub-account (also called “AttainKey”): Each client ID/counterpart ID must have at least 1—but could have multiple—sub-accounts (each in a different currency). For example, if a client is set up by default with a client ID (counterpart ID) and one EUR sub-account, all trading will happen on that EUR sub-account (including foreign shares, which will be converted to EUR). To avoid conversion costs, IAMs can open additional currency sub-accounts on behalf of their end clients via SaxoPartnerConnect. Trades will automatically be booked into a sub-account with a currency matching the instrument currency if it exists. You can see the sub-accounts of a specific client ID (counterpart ID) under the Account overview in SaxoPartnerConnect:
Please note: Each currency sub-account will have its own IBAN and can be funded directly with the relevant currency. It is also possible to convert funds between currency sub-accounts. Sub-account IDs can also be called an “AttainKey”: you may come across this name in EOD files, for example.
User ID (also called login ID, user login): This the specific ID an individual user enters to access the platform (SaxoPartnerConnect for IAMs and SaxoPortfolio for end clients). Each client ID (counterpart ID) can have several user IDs, depending on the account and client type:
- For a private end client, the counterpart ID is the same as the user ID.
- For a joint account, the main account holder uses the counterpart ID as the user ID, but the second account holder will have a separate user ID, which will differ from the counterpart ID.
- For a corporate account, the counterpart ID will never match the user ID, because each authorised dealer on a corporate account will have his/her own specific user ID. Even if there is only one user for a corporate account, the user will get a separate user ID.
Please note: this is the same concept as for your IAM top structure, where each of your users has his/her own user ID, but no user ID will match your IAM structure counterpart ID.
When resetting a password, the specific user ID is the ID that must be used. You can see the different user ID for a specific counterpart ID under the Users overview in SaxoPartnerConnect:
And you can also see the details/contact information for each user under Related contacts:
OwnerID: This is the client ID (counterpart ID) of the house or sub-house of your structure. The client is allocated underneath this ID. You can find more details about the logic and setup of house/owner structures here.
