Yes, Hertz consistently verifies eligibility for Counter Discount Program (CDP) codes, especially those associated with corporate contracts or exclusive organizations. While the discount is often applied automatically at the time of booking, Hertz's official policy for 2026 states that renters must present valid identification or proof of affiliation at the rental counter. If you are a member of the Gold Plus Rewards program, your credentials may be verified the first time you use a specific code. For all other renters, verification may occur at every rental. Using a corporate code for which you are not eligible can result in the discount being removed at the counter, being charged the full retail rate, or even being barred from future rentals. It is always best to ensure you have a digital or physical membership card, a business card, or a corporate ID that matches the CDP code used to avoid any complications during the pick-up process.
