Issuing
6.2 Card Standards and Specifications
If the Corporation notifies a Principal that a prefix number it sponsors is invalid,
the Issuer must replace all its Cards that use such prefix number within three
(3) months from date of notice. A prefix number is considered invalid when the
Issuer cannot produce written authorization of prefix assignment from ISO or
its designated representative(s). On the first Interchange System Business Day
following the three (3) months date of notice, the prefix number sponsored
by such Principal will be reassigned appropriately in the Interchange System
routing tables.
If it is discovered that more than one (1) entity validly owns a prefix number, as
evidenced by written authorization from ISO or its designated representative(s),
the entity that receives final assignment from ISO is determined to be the
rightful owner of such prefix number insofar as participation in Transaction
interchange in the Corporation is concerned.
If the Corporation notifies any Principal that a prefix number it sponsors is
in conflict with a prefix number of an entity that wishes to participate in
Transaction interchange in the Corporation, and such entity has established
prior rightful ownership of such prefix number, the Issuer currently using such
prefix number must replace all Cards that use such prefix number within three
(3) months from date of final assignment by ISO and certify compliance to the
Corporation. On the first Interchange System Business Day three (3) months
after ISO makes its final assignment, the prefix number sponsored by such
Principal will be reassigned appropriately in the Interchange System routing
tables.
6.2.1.4 Expiration Date
The expiration date must be a valid future date, four (4) digits in length, and
structured in a year-month format (YYMM).
Cards must not use a maximum validity period of more than twenty (20) years
from the date of issuance or, for non-expiring Cards, the designated default
value of 4912 (December 2049) must be used.
The expiration date of a hybrid Card must not exceed the expiration date of
any of the certificates contained within the chip on the hybrid Card. In the case
of a non-expiring hybrid Card, the following conditions must be met:
1. The settings within the chip contained on the hybrid Card must force every
Transaction online for authorization or decline the Transaction if online
authorization is not possible;
2. The hybrid Card must not contain an offline CAM certificate; and
3. The Issuer must utilize full EMV processing.
For additional information, refer to the chip technical specifications.
6.2.1.5 Service Code
