Questions of a general nature

  • What is METAPOSTA?

    The METAPOSTA digital mailbox is a secure, private and free channel made up of different solutions that facilitate the reception, signing, filing and legal custody of electronic documents.
    Access to the mailbox is very easy via a browser or the free METAPOSTA App. 
    METAPOSTA is designed for both individuals and organisations, complying with all of Spain's data protection laws.
    With METAPOSTA you can also receive electronic documents from certain issuers such as financial institutions (Laboral Kutxa, Kutxabank) and suppliers of utilities (Amvisa, Consorcio de Aguas de Bilbao…). METAPOSTA also allows you to upload documents of personal interest and sign them electronically, making them valid legally for public authorities. You have up to 1 GB of free space for the documents you upload to your mailbox.
    All the documents stored on METAPOSTA can be accessed from anywhere and at any time.

  • Will I be able to have several accounts with METAPOSTA?

  • METAPOSTA mailbox vs METABOX mailbox

    1- METAPOSTA mailbox

    1.a- Generated directly with METAPOSTA, via our website or the KZgunea centres.

    1.b- You can associate any Issuers that are active and with which you have a relationship (financial institutions, utilities...).

    1.c- You can store your own documentation up to 1 GB.

    2- METABOX mailbox

    2.a- Generated by the company/organisation with which you have a contractual relationship (employee, associate...)

    2.b- That company/organisation can send digital documents to your new mailbox or access your electronic signature, from a mobile device, on any of those documents.

    2.c- You can only receive documents: initially from the Issuer that set up your Metabox and then from other Issuers with which you have a contractual relationship and who have linked to you.

    2.d- You can't upload your own documentation.

    2.e-  You can convert your METABOX mailbox into a METAPOSTA mailbox via the mailbox itself.

  • Can minors sign up for METAPOSTA?

    Yes, as long as they have some form of valid ID (e.g. a Spanish ID card or DNI).

  • Can foreigners sign up for METAPOSTA?

    Yes, as long as they have some form of valid ID to prove their identity (e.g. Spanish foreign resident card or NIE).

     

  • NIE-DNI: changing my NIE mailbox to a DNI mailbox

    If you already have a METAPOSTA mailbox associated with a foreign resident number (NIE) and you've obtained a Spanish ID number (DNI), and you want to associate your mailbox with your new DNI, please take into account the following steps:

    1- This procedure can only be carried out via the Customer Service Centre (CSC) and you must therefore contact them: 

    https://www.metaposta.com/en/Contact

    2- The aim is for each user to have a single METAPOSTA mailbox where they can store all their important documentation.

    3- First download all the documentation you have in your mailbox associated with your NIE so you can upload it to the mailbox associated with your DNI.

    4- Senders: You'll have to re-assign all the Issuers who were associated with your NIE mailbox to your DNI mailbox.

    5- METAPOSTA mailbox vs METABOX mailbox: the procedure is different for each case (see: FAQ METAPOSTA Mailbox vs METABOX Mailbox).

  • Can I change the initial configuration of my virtual mailbox?

    Yes. Via "Set up my account" you can add, delete and modify your personal data and even change your password.

  • App: When you access a document via the App, what does the "Validate" button do?

    The "Validate" button verifies the validity of the signatures used on the document, via Izenpe.

     It's similar to when you access the "Signature List" tab on the web-based mailbox.

  • How much will this Service cost me should I sign up for it?

    It's free to sign up and use a virtual mailbox. Users can also store documents uploaded to the mailbox free of charge up to a limit of 1 GB.

  • I have forgotten-lost my passwords to access METAPOSTA. What must I do?

    To change your password, click on this link:

    https://www.metaposta.com/mp10mWar/mp10mRegeneracionClave.jsp?lang=es&appO=M

    It will take you to a screen where you'll be asked for your ID number (DNI or NIE). After clicking on the "I AM NOT A ROBOT" box, you'll be sent a password recovery email via which you can enter the password of your choice.

    There is an intermediate step, in which you'll be asked to confirm that the email address to which the email will be sent is correct and that you have access to it.

    This procedure can also be carried out via the METAPOSTA App.

    Remember that your new password must be at least 8 digits long and contain both letters and numbers.

    Check that it hasn't gone into your Spam or junk mail folder.

  • What would happen to my documents should I cease to be a client of the participating entity that sent them?
