N.D. Cent. Code § 51-29-02
A person may not charge additional monthly or annual service or maintenance fees on a gift certificate. A person may not limit the time for redemption of a gift certificate to a date before six years after the date of purchase of the gift certificate, place an expiration date on a gift certificate before six years after the date of purchase of the gift certificate, or include on a gift certificate any statement suggesting that an expiration or redemption date, except as permitted in this section, may apply to a gift certificate.
This section does not apply to a gift certificate distributed to a consumer pursuant to an awards, loyalty, or promotional program without any money or other thing of value being given in exchange for the gift certificate by the consumer. Any restriction or limitation on such gift certificate must be disclosed to the consumer, in writing, at the time the gift certificate is distributed to the consumer.
