The notification shall be made either by first-class mail with a certificate of mailing or by inclusion in any monthly or more frequent regular written communication. The MMO shall retain the certification of mailing pursuant to subparagraph 4803(a)(V). The MMO shall also notify former customers who were end-users during the period for which the refund is made that refunds are available, to the extent such former customers can be located.#

If the aggregate amount which remains unclaimed after 90 days does not exceed $100, the MMO may retain the aggregate amount.#
