REN batch code and freshness guide
This page is tuned for REN batch-code lookups, giving you a practical first-pass date reference in seconds.

These notes are organized around common REN coding behavior so you can avoid avoidable input errors.
- Enter one complete code string from a single package location instead of combining fragments.
- Short REN codes are easy to mistype, so compare the box print and bottle print before submitting.
- Decoding is an estimate; combine it with PAO symbols and open-date tracking for safer decisions.
- If possible, decode a sample lot before bulk buying to compare freshness across sellers.
