Yes, provided it is properly stored and the package is undamaged - commercially packaged whole wheat flour will typically carry a " Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the whole wheat flour will remain at peak quality.
• Storage time shown is for best quality only - after that, the whole wheat flour's texture, color or flavor may change, but in most cases, it will still be safe to consume if it has been stored properly, the package is undamaged, and there are no signs of spoilage (see below).
