Technical interfaces

Registrars may use either a browser-based user interface or an EPP interface defined by FICORA as the technical interface to the fi-domain name register.

Browser-based user interface

Registrars may log in to FICORA’s fi-domain name register via the browser-based user interface. Registrars log in using two-factor authentication via the link below.

Two-factor authentication means that the login requires a one-time password in addition to a user ID and password. The one-time password is an eight-digit password that is valid for only one login session. It is sent to registrars by text message.

In order to be able to log in, registrars must have already registered with FICORA.

EPP interface

EPP (Extensible Provisioning Protocol) is an XML-based technical interface. Domain name registrars can connect to the interface by using their own client software. FICORA does not provide ready-made client software and it is the registrar's responsibility to programme or acquire the client software. Registrars do not have to start using the EPP interface. Using both interfaces is also possible.

Registrars’ client software must be compatible with FICORA's EPP interface description which specifies the restrictions and extensions of interfaces based on the RFC documents.

Before a registrar can start using FICORA's EPP interface, the registrar's own client software must be tested in FICORA’s EPP sandbox environment.

The address for EPP interface is (port 700).

RFC standards

FICORA's EPP interface is mainly based on the following RFC standards:

KATAKRI requirements in the use of EPP interface

If a domain name registrar uses FICORA's EPP interface as the technical interface, it must meet the criteria derived from the requirements of the protection level (IV) of subdivision I, information assurance, of the currently valid version of Katakri (information security audit tool) with respect to the following:

  1. communications security
  2. system security.

In principle, the registrar is responsible for meeting the above-mentioned requirements. If necessary, FICORA may audit the registrar's operations.

Whois service of fi-domain names

Registrars may use FICORA’s whois service so that their customers are able to check whether a certain fi-domain name is available.

The whois service for fi-domain names is at To use the service, registrars need the whois client program that is included in most Unix and Linux operating systems.
