"US Government (GOV) Marriott code is the government rate requiring official federal employee credentials. Per GSA policy: "Government rates are available to federal employees who must show valid government-issued ID at check-in." This is not a negotiated corporate rate — it is a federally-contracted rate with mandatory verification requirements. Marriott properties are contractually obligated to enforce government rate eligibility. Multiple FlyerTalk users confirm: "Government rates at Marriott always require showing your government badge — no exceptions at any property type.""

"The hotels probably won't ask if you are a bonvoy member and have your company email on your account. If your reservation was booked thru a travel site with GDS link (like concur). Or if the rate is within 15% of the sell rate it's not worth the agro since aaa and qualified discounts are probably about the same discount rate as the corporate rate. However if you book High season/relatively low corporate rate, are staying over weekends don't have a history of stays on that corporate rate or are booking an event date like Superbowl you should plan on producing ID or proof of employment and be prepared to pay the retail rate for the room."

"I have been asked by the front desk on a few occasions but more often than not they don’t ask. I luckily used my corporate rate in the instances they asked: however, they can charge the rack rate which can be much higher than what you are prepared to pay so I would just go in with open eyes."
