I am trying to understand how this works.
If I use the code when renting a car for Chabad below (found from the Master Thread) and get a discount.
Do I need to show proof that I am Chabad?
How does it work?
"You may want to check out the master threads for each company to see if you are getting the best rate you can find yourself. The standards are;
Hertz: CDP 77694-USAA, AA, Chabad 1908469, BMG, AAA or 1906870;
Avis: AWD A177232-USAA, Costco (check thread) Chabad- X192286, BMG, or A144210
National: Great for one-way rentals try CID 5760333 or Nevada;
Enterprise: Chabad, BMG or USAA
Dollar: Chabad CL1111
Budget: Chabad U277223
but again depending on location of rental others might be better refer to master thread:
