How to Sort and Stamp Packages

Sorting packages in Cat Mail Co follows a consistent pipeline: pick up parcel, weigh on scale, enter stamp mode, apply all required labels and stickers, place in correct storage zone, repeat. Customer parcels additionally require scanner checks for fragile and heavy constraints after the scanner unlocks.

Efficiency comes from tight workspace layout, not speed. Keep the scale beside your processing desk and storage shelves within arm's reach. Our Package Handling guide documents every labeling requirement in text form.

Press F with a parcel in hand to open stamp mode. Navigate categories for destination labels, weight tiers, fragile stickers, heavy markers, and decorative stamps. Apply functional stamps first, then add decorative touches for bonus earnings. Exit stamp mode to return the parcel to the physical world.

Common mistakes include applying wrong weight tiers and forgetting constraint stickers after scanner detection. Use our Postage Reference Tool as a checklist until the process becomes automatic.

The video below demonstrates the complete sorting and stamping workflow during a demo session. Watch how the player handles customer parcels, uses the scale, enters stamp mode, processes the scanner introduction, and manages fragile and heavy constraints.

Batch parcels by destination before evening boat loading. Process all Port Windy mail together, then Sunny Shores batches separately. In co-op, the Postal Clerk handles stamp mode while the Organizer routes finished parcels to destination-specific shelves.

The Bulk Weighing upgrade from our Progression guide dramatically accelerates high-volume sorting sessions. Invest early if you process more than twenty parcels per shift.
