Mobile-ID PIN codes

Mobile-ID PIN codes are issued with your mobile-ID SIM card. You will find the codes under the disposable surface of the SIM card cover. You will receive three codes with the mobile-ID supported SIM card.

  • PIN1 code – for identification of a person or logging in
  • PIN2 code – for giving a digital signature or confirming transactions/activities
  • PUK code – for reopening locked mobile-ID PIN codes

We definitely recommend changing the automatically issued PIN and PUK codes as soon as possible. Choose PINs that are easy for you to remember, but difficult for others to guess. Always keep the PUK code in a secure place: this enables you to set new PIN codes if you accidentally forget or lock them.

Different PIN-codes have different length requirements:

  • PIN1 code must consist of 4-8 numbers;
  • PIN2 code must consist of 5–8 numbers;
  • PUK code must consist of 8 numbers.

Upon installing a mobile-ID supported SIM card, a mobile-ID menu will be added to your phone. This enables you to do all activities related to mobile-ID, such as change your PIN and PUK codes.

    If you have forgotten your PIN1 and/or PIN2 code and you don’t know your PUK code, the only way to continue using mobile-ID is by ordering a new SIM card. With mobile-ID, it is not possible to issue new PIN codes without replacing the SIM card.

    You can read more about changing Mobile ID and PIN codes on the operator's website:

    If you have your PUK code, you can recover and change your PIN codes via the mobile-ID menu on your phone. NB! The PUK code will lock upon entry of the wrong code three times in a row. In the event of a locked or lost PUK code, you must also replace your SIM card to continue using mobile-ID. You can get a new SIM card by contacting your carrier.

Open a selection of apps (applications, apps) on your phone and choose either Telia (Telia), Tele2 Menu (Tele2) or Elisa (Elisa) according to your mobile operator. Some models may also feature a Mobile ID, SIM toolkit, or a SIM toolkit-named application.

    For you to remember PIN codes, but your electronic identity to remain secure, you should change the automatically issued PIN and PUK codes.

    Recommendations for selecting secure PIN codes:

    • Choose such PIN and PUK codes that are easy for you to remember, but difficult for others to guess.
    • Don’t make your PIN1, PIN2 and PUK codes the same! Create a system known only to you which helps you remind yourself of the right code, if necessary.
    • Using dates meaningful to you in PIN codes is a good idea only if these dates are not obvious to anyone else. Avoid using the birthdays of you and your family members, your wedding date, etc.
    • Do not use too simple number combinations (0000, 1111, 1234, etc.), your address or personal identification code as your PIN codes.

    How to keep PIN codes safe?

    • Learn your PIN codes by heart! If you are afraid that you might forget them, write the codes down in a cipher: for example, mask them into telephone numbers and keep them in a safe place away from your computer and phone.
    • Never keep your mobile phone and PIN and PUK codes in the same place. If you seldom need your PIN codes, there is a risk that you may forget them and so it is convenient to keep the codes to hand. However, don’t do this because if a malicious person happens to be in your home, office or near your purse, you may lose your phone as well as fall victim to identity theft.
    • If you give your phone to another person, don’t share your mobile-ID PIN and PUK codes with them. If you suspect that your PIN codes are known to someone else who might have access to your smart device, you should change your PIN and PUK codes.

    What to do if your mobile phone is stolen or lost?

    If you have lost your mobile-ID SIM card (it mostly happens with the loss or theft of your smart phone), immediately inform your mobile operator thereof.

    The mobile operator can then suspend your mobile-ID certificates – this keeps you safe from identity theft.

    If you find your phone again, you can continue using the old SIM card for making calls, sending messages, etc., but for restoring mobile-ID functionality, you need to order a new mobile-ID SIM card from your mobile operator. Contact your operator to order a new mobile-ID SIM card.
