"hotelcorporatecodes.com lists Target N4083735 in the "Sometimes" verification tier. Target is one of the most-searched Hilton corporate codes online (high sharing volume), which correlates with higher hotel-side suspicion.

"- Marriott (CORP): Please be prepared to show proof of eligibility for your rate (such as a membership card, corporate or government identification card, or proof of your age). - Marriott (GOV): Federal Govt issued Visa, MasterCard, American Express, or Federal Govt picture ID (CAC or Common Access Card) - Hilton (CORP): No ID requirements listed - Hilton (GOV): Id-travel orders required at checkin"

"I know that previously the Hertz IBM rate was always fixed in the mid $30s for a full size vehicle with last car availability. A minivan was $175/week in Orlando even during President's week when the going rate was about $1,200. This is probably why Hertz and at least Avis has been more strict. I have found Marriott to be very strict, especially at key locations, when it comes to the government rate. Marriott wants travel orders, a government ID, and/or a government credit card. I found Hilton to be less strict for those government rates."
