Post Office Tidy Up Achievement List: What They Ask

Post Office: Tidy Up has an achievement list, but the exact size depends on who you ask. Steam's appdetails API reports 26 achievements; Exophase tracks 19; TrueSteamAchievements says the base game contains 0 and puts 26 in a DLC pack. A first-look walkthrough from launch week says it is "going through all 19 achievements", which matches the Exophase figure.

The safest reading is that 19 are base-game milestones and the rest arrive with add-on content, but that is an inference rather than a developer statement. Treat any list of exactly 26 as unverified until Steam's own achievement page agrees.

The early milestones

The first few are exactly what you would expect from a sorting game, and they double as a tutorial checklist:

Achievement	Requirement
First Stocked	Place your first package on the correct shelf
100 Stocked	Correctly place 100 packages on shelves
1,000 Stocked	Correctly place 1,000 packages on shelves
2,000 Stocked	Correctly place 2,000 packages on shelves
25 Racks	Fill 25 racks
Fully Certified	Take every line of the skill tablet to its last step

The 1,000 and 2,000 tiers are the ones that set the pace: with 3,268 parcels in the office, reaching 2,000 stocked means most of the campaign, not a side task.

The odd ones

Two achievements break the pattern. One asks you to throw 100 packages — its description reads "Delivery time improved, but the packaging did not." The other is Employee of the Month, which the walkthrough unlocks by picking up the bin near the computer; its description is "Meet the only member of staff who sorts nothing."

That second one is worth flagging because it is easy to miss: it is not tied to sorting progress but to interacting with a specific object in the office. If you are cleaning up the list after finishing the shelves, the bin by the computer is the first place to look.

Why the counts differ

Steam's API counts every achievement attached to the app, including content that may be gated behind add-ons; Exophase and TrueSteamAchievements split base game and DLC differently. The walkthrough's "19" is a player-facing count from the build that shipped at launch.

Until the developer publishes an official list, use the in-game achievement page as the source of truth. For the Employee of the Month step itself, see employee of the month.
