ECI values

An Electronic Commerce Indicator (ECI) value is the response to an authentication attempt with 3D Secure (3DS). It indicates the level of authentication and the liable party in the event of a transaction dispute.

Mastercard-specific ECI values

Note that Mastercard uses a different set of ECI values than other schemes. The following values apply strictly to Mastercard.

ECI value	3DS authentication result	3DS version	Liability shift
00	Authentication attempt failed or could not be attempted.	3DS 2.2.0 and 2.3.1	No.
01	3DS authentication was successfully processed by a stand-in service.	3DS 2.2.0 and 2.3.1	Yes.
02	3DS authentication was successful. The transaction is secured by 3DS.	3DS 2.2.0 and 2.3.1	Yes.
04	Frictionless authentication via the Mastercard Identity Check Data Only service.	3DS 2.2.0 and 2.3.1	No.
06	The transaction is out of scope or exempt from Strong Customer Authentication (SCA).	3DS 2.2.0 and 2.3.1	No.
07	3DS authentication was successful. The recurring transaction is secured by 3DS.	3DS 2.2.0 and 2.3.1	Yes, but not for transactions processed through Apple Pay without a cryptogram.
N0/N2	A non-payment authentication was processed. This type of transaction does not go to authorization, so the liability shift does not apply.	3DS 2.2.0 and 2.3.1	No.
