1. Contact us, register on PRISMA and/or with IAM partners

a) Contact us
Phone: +44 (0)20 3621 7800

    3. Accept contract terms

    Have signed up to the IUK Access Agreement and IUK Access Code.


    4. Meet credit requirements

    If your company holds a long term debt rating which is at least BBB+ (S&P), Baa1 (Moody's) or BBB+ (Fitch) then you will not be required to provide credit support. For more info, please see Clause 2.9 of the IUK Access Agreement (IAA).

    Credit can be provided as cash cover, a Guarantee (IUK template here) or a Letter of Credit (IUK template here).


    5. Approved as a shipper

    • You will be approved as a Shipper when you receive a fully signed contract back from us. We will then issue you a unique IUK Shipper code.
    • If you have registered with PRISMA, IUK will now accept this and an email is automatically generated - the account will be effective from 06:00 hours CET the following day.
    • You will be issued a SPOC user form (single point of contact) and the user will be set up on EDP (Electronic Data Platform). An email informing the user of their username followed by a SMS with password will be issued.
    • You can then advise us if you will use Edig@s (AS2/AS4)- if so a connection point will be configured, finalising the setup.

    The IUK sign up process is expected to take approximately 5 business days following the receipt of a satisfactory KYC.
    For any questions please email or call +44 203 621 7800 and Sarah or Charlotte will be happy to help.
