New BankID (NO) Signing Service

Stø is introducing a new BankID signing service, phasing out the current signing service based on the old ‘BankID Server’ technology. The solution supports signing multiple documents simultaneously and meets the strictest EU requirements for digital signing, qualified signatures. Please note that Stø has extended the deadline from December 31, 2025 to April 1, 2026. For more details refer here Important Notice: Action Required for Upcoming Changes to BankID Norway by April 1, 2026

We would like to inform you of the following key changes that will take effect as part of our service updates:

1. iframe Support Discontinued – From this date, iframe-based integrations will no longer be supported. Customers currently using iframe must update their integrations.

2. SSN Handling via Certificate – Going forward, the Social Security Number (SSN) must be retrieved directly from the Certificate-SSN. The Norwegian National Identity Number (NNIN) will be included in the public certificate as a custom extension, using the following Object Identifier (OID): 2.16.578.1.61.2.4

3. Change in Revocation Data Format – The current use of UserCertificateAndRevocationData/RevocationValues/XAdES:OCSPValues will be replaced by: UserCertificateAndRevocationData/RevocationValues/XAdES:CRLValues. This change affects how certificate revocation information is processed and validated.

4. Introduction of Qualified Electronic Signatures (QES) - Signing will be upgraded to QES, offering enhanced legal validity and security in compliance with EU eIDAS regulations
