Kingdom Hearts Final Mix Postcards Overview
Traverse Town contains 10 Postcards that can be mailed through the mailbox in the First District. Each postcard produces a separate item, and you can mail them individually instead of waiting until the full set is collected.
Several locations are immediately accessible, while others require story progress, access to specific shops, or a short environmental puzzle. The most efficient approach is to sweep the First District first, then move through the Second and Third Districts once the required paths are open.
Video Highlights:
- All 10 postcard locations are shown across Traverse Town.
- Early pickups include the blue safe, shop rooftops, the item shop fan, and a Blue Trinity chest.
- The Gizmo Shop clock requires Thunder before its two postcards become available.
- The final rewards include AP Up and Defense Up.

First District Postcard Locations
The First District contains most of the straightforward pickups. Check the blue safe, shop rooftops, item shop, Synthesis Shop, and Geppetto’s House. Some positions are hidden above normal eye level, so use the camera to inspect roofs, balconies, ceiling fixtures, and corners.
| Postcard | Location | How to Reach It | Reward |
|---|---|---|---|
| #1 | Blue safe | Check the blue safe in a First District corner | Cottage |
| #2 | Accessory and synthesis shop roof | Jump onto the roof above the connected shops | Mythril Shard |
| #3 | Blue Trinity balcony chest | Perform the Blue Trinity near the cafe, then open the chest | Mega-Potion |
| #4 | Item Shop ceiling fan | Strike the ceiling fan inside the Item Shop | Mega-Ether |
| #9 | Synthesis Shop | Search behind the paper near the back of the shop | Orichalcum |
| #10 | Geppetto’s House | Inspect the corner beneath the small jar or pot | Defense Up |
Blue Safe and Shop Roof
The blue safe is one of the simplest pickups in the entire set. Search the corner of the First District rather than looking for a chest prompt. The second postcard rests on the roof above the Accessory Shop and Synthesis Shop. You can reach this roof without Glide by extending your jump with a Keyblade strike, although the jump is easier after gaining additional movement abilities.
Blue Trinity Balcony Chest
The Blue Trinity near the cafe reveals access to a balcony chest. Activate the Trinity, climb to the newly accessible area, and open the chest to receive another postcard. This location is worth checking early if Sora already has the required Trinity ability.
Item Shop Ceiling Fan
Inside the Item Shop, look upward toward the ceiling fan. Strike the fan until the hidden item drops. The angle can be awkward, and repeated attempts may be necessary. Reposition Sora beneath the fan rather than repeatedly attacking from the same spot.
Synthesis Shop and Geppetto’s House
The Synthesis Shop postcard is hidden behind a piece of paper near the interior wall. It becomes available once the shop can be entered. Geppetto’s House also contains a hidden postcard, but it is not in the obvious chest. Search the corner beneath the small container to collect it.
The Geppetto’s House postcard is easy to miss because the nearby chest draws attention away from the actual item location. Check the floor-level corner beneath the jar or pot.
Second and Third District Locations
The remaining postcards use rooftops, balconies, and the Gizmo Shop clock. These pickups are more sensitive to positioning than the First District items. Clear nearby enemies before making difficult jumps, and avoid rushing across narrow walkways.
| Postcard | District | Location | Main Requirement |
|---|---|---|---|
| #5 | Second District | Chest above the boots and shoes shop | Rooftop access or a careful jump |
| #6 | Second District | Gizmo Shop clock | Activate the clock mechanism |
| #7 | Second District | Gizmo Shop clock | Activate the clock mechanism |
| #8 | Third District | Rooftop balcony corner | Reach the upper balcony through the roof route |
Boots and Shoes Shop Chest
In the Second District, look above the boots and shoes shop for a chest positioned on an elevated ledge. A nearby light or pedestal can provide the height needed for the jump. High Jump is not required for this pickup, but the approach is more forgiving if you use the local platform carefully.
Third District Blue Trinity Chest
The Blue Trinity route near the First District cafe leads to a chest on a balcony. This is distinct from the later Third District rooftop balcony postcard. Track both locations separately so you do not mistake one balcony pickup for the other.
Rooftop Route to the Balcony
To reach the upper balcony, enter the Gizmo Shop area and climb the ladder when the route becomes available. Cross the rooftop walkway and pass through the opening leading toward the Third District. The postcard is placed in an otherwise unremarkable corner of the balcony.
| Route Stage | Area | Action | Result |
|---|---|---|---|
| 1 | Gizmo Shop exterior | Climb the ladder when available | Reach the upper rooftops |
| 2 | Rooftop walkway | Cross the roof and enter the opening | Access the Third District balcony route |
| 3 | Balcony | Defeat enemies if needed and inspect the corner | Collect Postcard #8 |
| 4 | First District | Return to the mailbox | Mail the postcard for its reward |
Narrow walkways make accidental falls common. Remove nearby enemies before crossing, and use short controlled jumps instead of holding forward through the entire route.
Gizmo Shop Clock Puzzle
Two postcards are hidden in the Gizmo Shop clock. They do not appear until you activate the mechanism in the Third District with Thunder. After the spell is used, return to the Gizmo Shop and use the raised platforms to reach the large buttons.
The room provides limited jumping space, so platform positioning matters. Strike all three buttons, then wait for the clock to finish spinning. When the clock settles at 6:54, the two postcard pickups become available.
Reach the Third District
Enter the Third District through the available Traverse Town route. Clear enemies around the mechanism if they interfere with spellcasting or movement.
Cast Thunder
Use Thunder on the electrical mechanism in the Third District. This activates the Gizmo Shop platform sequence.
Return to the Gizmo Shop
Re-enter the shop and climb the raised platforms. Use the platforms to move between the three large buttons.
Strike Every Button
Hit all three buttons. The final button is around the corner and may require a wider platforming approach.
Wait for 6:54
Let the clock spin until it stops at 6:54. Collect both postcards from the clock face.
| Clock Pickup | Activation | Collection Method | Reward |
|---|---|---|---|
| #6 | Thunder mechanism activated | Hit the first three Gizmo Shop buttons, then wait for 6:54 | Elixir |
| #7 | Same clock sequence | Collect the second item when the clock locks at 6:54 | Mega-Elixir |
Platforming Advice
Do not jump directly toward every button from the floor. Use the raised platforms to create shorter, safer hops. The ceiling limits vertical movement, so a jump that looks open may still collide with the room’s upper structure.
If Sora misses a button, reset his position on a nearby platform before trying again. The puzzle is easier when approached methodically rather than through repeated long jumps.
The two clock postcards are unavailable until the Third District mechanism has been activated with Thunder. If the platforms are still lowered, progress the puzzle instead of searching the clock face.
Mailbox Rewards and Collection Checklist
The mailbox is located in the First District. Mailing a postcard immediately grants its associated item, and the rewards do not require all 10 postcards to be collected first.
| Mailing Order | Reward | Item Type | Collection Note |
|---|---|---|---|
| 1st | Cottage | Recovery item | Mail any first postcard |
| 2nd | Mythril Shard | Synthesis material | Mail any second postcard |
| 3rd | Mega-Potion | Recovery item | Mail any third postcard |
| 4th | Mega-Ether | MP recovery item | Mail any fourth postcard |
| 5th | Mythril | Synthesis material | Mail any fifth postcard |
| 6th | Elixir | High-grade recovery item | Mail any sixth postcard |
| 7th | Mega-Elixir | High-grade recovery item | Mail any seventh postcard |
| 8th | Orichalcum | Synthesis material | Mail any eighth postcard |
| 9th | AP Up | Stat item | Mail any ninth postcard |
| 10th | Defense Up | Stat item | Mail the final postcard |
The reward is tied to the number of postcards mailed, not the physical location from which each postcard was collected. This means you can collect #10 before #1 and still receive the first reward if it is the first postcard placed in the mailbox.

Common Questions
The postcard side quest is short but contains several easy-to-miss interactions. Use the answers below to resolve the most common collection problems before retracing every district.
Q: Where do I mail the Kingdom Hearts Final Mix postcards?
Take every postcard to the mailbox in the First District of Traverse Town. Mailing them one at a time is allowed, so you do not need to hold the entire set.
Q: Do I need to collect the postcards in numerical order?
No. The postcards can be collected in any available order. The reward sequence depends on how many have been mailed, not which numbered postcard you submit.
Q: Why are the Gizmo Shop clock postcards unavailable?
Use Thunder on the electrical mechanism in the Third District first. Then return to the Gizmo Shop, activate all three buttons, and wait for the clock to stop at 6:54.
Q: Is High Jump required for every rooftop postcard?
No. The elevated Second District chest and the Accessory and Synthesis Shop roof can be reached with careful positioning and jump extensions, although movement abilities can make the route easier.
For a broader reference on the Kingdom Hearts series, consult the official Kingdom Hearts website. For this specific side quest, prioritize the location order, the Thunder-triggered clock sequence, and the final mailbox rewards listed above.
Once the mailbox has produced Defense Up, all 10 postcards have been mailed and the Traverse Town postcard quest is finished.
