    How to verify an e-mail address for users with several Supplier Accounts

    For Users with several Supplier Accounts linked to the same E-Mail Address

    If you have more than one supplier account that all refer to the same e-mail address, you can link your accounts: you will have one main account and several subordinate accounts.

    Please note:

    The first supplier account for which you verify your e-mail address will automatically become the main account. 

    Once set, you cannot change the main account by yourself as of now. The only way to change your main account is to open a ticket at the Supplier Helpdesk and ask them to reset your main account. After the reset, you then verify the e-mail address of the account that should become your main account. Afterwards, you verify the e-mail addresses of all your other accounts.

    Step-by-Step Instructions:

    To verify the e-mail address of your main account, please follow the instruction mentioned above (for users with exactly one supplier account)

    For all of your other (subordinate) accounts please follow these steps:

    • Log on to the Supplier Portal with one of your subordinate accounts (not the main account). After logon, you will be redirected to the linking page where the data of your main account will be displayed (supplier ID and e-mail address).
      You cannot change the e-mail address in this step.
    • By clicking on “Link your account” you confirm that you want to link both accounts.
    • You will be redirected to the Mercedes-Benz logon page where you have to log on with the credentials of your main account (user id and password).
    • After the logon, you will be redirected to the linking page again. A confirmation page informs you that the two accounts have been successfully linked with each other. Both accounts are now verified.

    You need to repeat these steps for all of your subordinate accounts until every account is linked and verified.

    How to verify an e-mail address for users with several Supplier Accounts linked to a Shared Mailbox

    For Users with several Supplier Accounts linked to the same Shared Mailbox

    In general, you should always link your supplier account to a personal e-mail address and not to a shared mailbox address used by more than one person (

    If you want to continue using a shared mailbox, the steps remain the same as mentioned above: 

    The supplier account who verifies his/her e-mail address first, will become the main account. All other supplier accounts that start the e-mail verification process later will need to contact the person using the main account during the verification process. Since you need the user id and password of the main account during the linking process, you need to carry out the linking of the accounts together.

    Why can‘t I log into an application?

    Your user status is “inactive“, mostly caused by the e-mail status attribute: as long as you have not verified your e-mail address, your status will be “not verified“ – which leads to an overall “inactive“ status. Other reasons for inactivity: your user may have been blocked by an admin, the validity of your user is invalid, your home-organisation is invalid, …

    User can`t login because the Login Mask will lead him to the verification process.

    User has to verify his e-mail address first then he can login to the system.

    How do I know wich User ID is the Main ID?

    Within the account linking process, the main ID is shown in the linking page.

    After account linking, a portal manager can view the main ID in the “LDAP-View“ in GEMS (see picture) with a later release, This will also be visible in the user overview page.

    I have multiple accounts with the same e-mail address. Which account will become Main account? Which account should I choose?

    • The first account for which you make the verification will become the main account.
    • You can choose the account that fits you best, there is no rule.

    I have accidentially verified the „wrong user“ as first user/Main account.

    Please send an email to our support ( and ask them to reset the verification for this user. Then you can do the verification with another user, which then becomes the Main ID.

    Can I change my Main ID?

    Currently there is no function available, but this is planned for a future release. As a temporary workaround, you can request this at support.supplier-Portal@mercedes-benz.comThen our support will reset the verification for the user.

    Where can I see which accounts are linked to my Main account ID?

    Currently there is no function available, but this is planned for a future release. We will make this visible for portal managers in the users overview page in GEMS.

    Where can I see the e-mail status of a user?

    The e-mail status of a user can be seen in GEMS in the users overview page:

    The e-mail status will also be integrated in the GEMS user reports in the next weeks.

    Why can I as a portal manager do not make a password reset for users anymore?

    After the user has verified his e-mail address, a portal manager cannot reset user passwords anymore. A password reset can only be done by the user in self-service in the Credential Management Tool via his e-mail address.

    User did not receive an email with the confirmation link.

    • User should first check his/her SPAM folder.
    • User should login again into the Supplier Portal and request a new confirmation link by starting the verification process again. Maybe the entered e-mail address was wrong.

    I have my supplier account for years and never had to do this.

    Due to new regulations it is necessary that every user has a unique and personalized e-mail address which will be verified. The benefit is that users can easily reset their password via email in the future.
