Complications in preparing and preserving quantum correlations stimulaterecycling of a single quantum resource in information processing andcommunication tasks multiple times. Here, we consider a scenario involvingmultiple independent pairs of observers acting with unbiased inputs on a singlepair of spatially separated qubits sequentially. In this scenario, we addresswhether more than one pair of observers can demonstrate quantum advantage insome specific $2 \rightarrow 1$ and $3 \rightarrow 1$ random access codes.Interestingly, we not only address these in the affirmative, but alsoillustrate that unbounded pairs can exhibit quantum advantage. Furthermore,these results remain valid even when all observers perform suitable projectivemeasurements and an appropriate separable state is initially shared.
