Golden codes are the single digit codes from 1 to 9.
Each accommodation in the world has one World Hotel Code which has been created for them free of charge.
Free codes are those above the number 1000, which will be joined with WCC to create a WHC, which is exclusively and permanently registered for each hotel.
Any super level hotel can purchase an available golden code, which will replace the previous free code after payment. The accommodation will then become a member of Golden Code group, and will be able to introduce themselves to the world, using their golden code.
