National Emerald Club: Free Membership with Rental Credits and Aisle Benefits

National Emerald Club is free to join and focuses on faster car-rental pickup plus rewards on qualifying National rentals. National’s current program pages say the entry Emerald Club tier earns one rental credit for each qualified rental, with seven credits redeemable for a free rental day up to a Midsize vehicle under the program rules. At participating Emerald Aisle locations in the United States and Canada, members can choose an eligible Midsize-or-higher car from the aisle and pay the Midsize rate. National also documents global regions where free rental days can be redeemed. Reward days cover the base rate rather than every charge, and benefits differ by country, location and vehicle availability. The membership is free; the rentals, taxes, fees and optional extras are not.
