Finnish Trust Network (FTN): how to accept Finnish bank IDs

How a business accepts the Finnish Trust Network: choosing a tunnistuspalvelu, what a sign-in returns, the 3-cent legal cap, AML and AMLR standing, limits for foreigners and minors, and the document fallback.

In short

The Finnish Trust Network (FTN, luottamusverkosto) is the legally regulated network that lets a business accept Finnish bank IDs and mobile certificates through one identification broker, a tunnistuspalvelu.[1] Every registered means provider must offer its means to every registered broker, and the law caps the provider's fee at 3 cents per identification.[1][2]

  • A sign-in returns the name, the date of birth and the personal identifier. No portrait.[15]
  • Bank IDs and mobile certificates are rated Substantial in Finland[3] and are not EU-notified.[4]

Last reviewed: 5 October 2026 · Not legal advice

In Finland, strong electronic identification (vahva tunnistautuminen) means a bank ID, a mobile certificate or the ID card chip. A business signs one contract with a tunnistuspalvelu, a registered broker, and reaches every provider in the network.[1][3]

The Finnish Trust Network at a glance

The network was formed on 1 May 2017 by all notified providers, meaning the providers notified to Traficom's national register, not the EU eIDAS list.[1] The National Cyber Security Centre Finland (NCSC-FI) at Traficom keeps the register and supervises it.[1]

How many Finns use strong identification

We found no official 2025 total of users or identifications from Traficom or the Digital and Population Data Services Agency (DVV), as of 5 October 2026.

2.8 millionPeople whose strong identification to public e-services triggered the Suomi.fi Messages prompt from 12 May 2025, according to Suomi.fi

Sources: Suomi.fi news, the Traficom register and Finlex.[3][2]

The register of 16 June 2026 lists the banks, the three mobile operators' certificates, one wallet app and DVV's citizen certificate as means.[3] The mobile certificate needs a subscription with one of those three operators.[14]

What the user sees

The user chooses a bank or a mobile certificate and signs in on that service's own screens: a username and password plus an app approval, a key-code list or a separate code device, depending on the bank.[3][15]

Verify your identity

Use the eID you already have.

The mobile certificate (Mobiilivarmenne) sits on the SIM, so it has its own path after step 2.[3]

  1. The user picks the mobile certificate at the chooser.
  2. The user types their own phone number.[14]
  3. The user approves on the phone with a self-chosen PIN.[14]
  4. Consent and return, as in step 5.

The operators claim that 99% of services accept the mobile certificate (mobiilivarmenne.fi, a site run by the operators).[14]

What the Finnish Trust Network returns to a business

The broker passes back a signed identity: the name, the date of birth and the personal identifier when the selected method returns them.[15]

AttributeWhenNotes
Full nameReturnedFrom the bank or operator record[15]
Date of birthWhen returnedProves age[15]
Personal identity code (henkilötunnus)When returnedFinland's national identifier[15]
Electronic ID number (SATU)Citizen certificate8 digits plus a check character; reveals no date of birth[12]
AddressNever by defaultPlan another source
PortraitNeverNot part of the result[15]

What a completed FTN sign-in carries.[15][12]

The ID card stores no personal identity code, date of birth or address, only the SATU, so a broker resolves the identifier to a henkilötunnus via the population register.[12]

Watch out

No address and no portrait. If your due diligence needs either, add a second source and a liveness and face step from day one.[15]

Vahva tunnistautuminen and the law: level of assurance and legal standing

The governing law is Act 617/2009, titled since amendment 811/2026 of 4 September 2026 "Laki vahvasta sähköisestä tunnistamisesta" (previously "...ja sähköisistä luottamuspalveluista"), the Act on Strong Electronic Identification.[2]

InstrumentWhat it means for FTN
Act 617/2009, § 12 cCaps the means provider's fee, paid by the broker, at 3 cents per forwarded identification, all identity data included[2]
Act 617/2009, § 17For a means provider's initial identification, permits reliance only on a valid EEA, Swiss or San Marino passport or ID card, or a DVV digital identity certificate, and requires means providers to accept other providers' strong means at the same or a lower level[2]
EU notified-schemes listOnly the citizen certificate on the ID card, High, 25 April 2025, C/2025/2448[4]
Act 444/2017, chapter 3, § 11Remote identification: one option is a strong identification means under 617/2009[5]
Act 444/2017, chapter 3, § 1(12)Data obtained through eIDAS identification means may be stored as customer due diligence data[5]
Regulation (EU) 2024/1624, Art. 22(6)(b)eID means at Substantial or High, from 10 July 2027[6]

The anti-money laundering act names FTN means directly.

Chapter 3, § 11Rahanpesulaki 444/2017, as amended by 818/2026

"todentaa asiakkaan henkilöllisyys vahvasta sähköisestä tunnistamisesta annetussa laissa (617/2009) tarkoitetulla tunnistusvälineellä"

Source: Finlex, 444/2017[5]

In English, one option for remote identification: "verify the customer's identity with an identification means referred to in the Act on strong electronic identification (617/2009)".[5]

From 10 July 2027 the EU Anti-Money Laundering Regulation (AMLR) applies. Its Article 22(6)(b) accepts "electronic identification means which meet the requirements of Regulation (EU) No 910/2014 with regard to the assurance levels 'substantial' or 'high'".[6] The final draft due diligence standards of the Anti-Money Laundering Authority (AMLA), sent to the Commission on 30 September 2026 and not yet law, say eID means qualify "regardless of whether they are notified" if they meet Substantial or High, and note that "this includes European Digital Identity Wallets" (EUDI Wallet).[7] Our reading: a Substantial FTN sign-in fits, notified or not.

Note

DVV's own Suomi.fi Wallet app is now planned for 2027, after EU certification delays. An October 2025 government plan had said the end of 2026.[13]

How to connect: choosing a tunnistuspalvelu

The register of 16 June 2026 lists four pure brokers and seven providers that both issue means and broker: banks, the three mobile operators and a wallet app provider.[3]

Gambling is the big change. Licence applications opened on 1 March 2026, and from 1 July 2027 "All gambling will require identification to verify age", with an age limit of 18.[8]

Limits and fallbacks

A Finnish bank ID needs an account at a Finnish bank, and usually a Finnish personal identity code.

  • Foreigners: the Finnish Authenticator app serves only selected public services.[11] Residents with a residence permit can get the citizen certificate.[12]
  • Minors: banks set their own age rules (see the FAQ).

Outages happen. On 17 September 2025, from 04:00 to 08:23, bank IDs and the mobile certificate failed in Suomi.fi identification.[10] Fraud is the other limit. According to Finance Finland (Finanssiala), criminals tried to take EUR 148 million from Finns in 2025. Banks blocked or recovered EUR 75.5 million and EUR 72.5 million was lost. Safe-account scams (turvatilihuijaus), where callers pose as the bank, cost EUR 38.4 million.[9]

For everyone else, the fallback is a document check: read the passport or ID card chip over NFC (near-field communication), check liveness and match the face (see NFC eID verification and chip security).

Finnish Trust Network integration checklist: tunnistuspalvelu, data and fallback

  • Choose a broker from the current Traficom register.[3]
  • List the attributes you need and an address source.
  • Offer both bank IDs and the mobile certificate.
  • Store the result as due diligence evidence (Act 444/2017, chapter 3, § 1(12)).[5]
  • Build the document fallback for users without FTN.
  • Test success, cancellation, expiry and fallback.
  • Plan age checks for gambling before 1 July 2027.[8]
  • Recheck your policy against AMLR before 10 July 2027.[6]

How Didit helps with Finnish Trust Network verification

The Finnish Trust Network is live on Didit, so you need no broker contract of your own. The user picks it in the hosted flow or the SDK, on the same phone or by QR code from a computer. Didit never asks for the PIN or the bank password.

Turn it on in the console under Workflows, ID Verification, Countries, Finland, Wallets accepted, or with the workflows API (methods.FIN.wallet).

Users without FTN fall back to document checks with NFC chip reading ($0.15), liveness and face match in the same workflow. A full KYC check costs $0.33; AML screening $0.20. Only completed FTN sign-ins are billed, at $0.25 (pricing). Every eID Didit runs is listed on the digital ID wallets page.

A completed FTN sign-in is one identification step inside your workflow, not a full onboarding. It gives you the full name, the date of birth, the Finnish personal identity code, the level of assurance (labelled Substantial) and a signature check. It does not give you an address, a portrait or a risk decision.

Didit provides

  • Finnish Trust Network sign-in in the hosted flow or the SDK
  • The document route for users without FTN
  • The signed attributes and the evidence of every check

Stays with you

  • The risk assessment and the policies
  • The onboarding decision
  • The source for the customer's address

Frequently asked questions

What is the Finnish Trust Network?

A legally regulated network, formed on 1 May 2017, in which every registered means provider must offer its means to every registered broker. A business signs with one broker and reaches them all.[1]

How much does an FTN identification cost?

The law caps the means provider's fee at 3 cents per forwarded identification, all identity data included. Separately, broker charges vary by provider and contract; check current pricing.[2] Didit charges $0.25.

What data does a business receive?

The name, the date of birth and the personal identity code (henkilötunnus) when the chosen method returns them. There is no address by default and no portrait.[15]

Is FTN eIDAS-notified?

No. Finland's only EU-notified scheme is the ID card's citizen certificate, at High since 25 April 2025.[4] Bank IDs and mobile certificates are Substantial under Finnish law.[3]

Can FTN be used for AML customer due diligence in Finland?

Yes. The anti-money laundering act, chapter 3, section 11, on remote identification, lists verifying the customer's identity with a strong identification means under Act 617/2009 as one option.[5]

Will FTN still work for KYC under the AMLR?

Article 22(6)(b) accepts eID means meeting the eIDAS Substantial or High requirements from 10 July 2027. FTN means are not EU-notified, so the article alone does not settle it; AMLA's final draft standards, not yet law, accept non-notified means, so in our reading FTN fits.[6][7]

Can foreigners use the Finnish Trust Network?

Only with Finnish bank credentials or a Finnish mobile certificate. The Finnish Authenticator app covers selected public services only, so private services need another route, such as a document check.[11]

Can minors sign in with FTN?

Some can. Banks set their own age rules; according to S-Pankki, it issues bank IDs from age 12. The citizen certificate on the ID card needs every guardian's consent.[12]

How long does an FTN integration take?

Lead times are not published, as of 5 October 2026. With a broker, its own onboarding schedule sets the lead time. Becoming a broker yourself means notifying NCSC-FI and submitting audit reports, valid for up to two years, so plan for re-audits.[1]

How do I test an FTN integration?

Test access comes through the broker you contract with. The broker register is public, but we found no published shared test environment, as of 5 October 2026.[1][3] Run real sign-ins covering success, cancellation, expiry and the document fallback, because a sandbox result does not prove a real bank sign-in.[15]
