How long do Potatoes last in the pantry?
Turning the range into a date
Potatoes keep 1–2 months in the pantry from purchase. Each kind gets its own dated rows here, 5 rows across the 2 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

The USDA rates 2 kinds of this separately
The USDA files 2 separate entries under this name — USDA record 297 and instant — and they do not keep for the same time: Potatoes holds 1 month to 2 months outside the freezer, Potatoes, instant holds 10 months to 15 months.
The freezer helps less here than you would expect
The freezer buys less here than its reputation suggests: 6 times what the pantry gives, 2 months against 12 months, both still measured in months. For this item freezing is an extension rather than a different way of keeping it. On the same shelf it sits 8 of 89, between Onions at 2 months and Spaghetti squash at 2 months. Potato and instant are the same food in the source list.
Every storage figure the USDA publishes for this item
All three places the USDA recognizes are rated here — pantry, refrigerator and freezer — which only 65 of the 466 foods in the data manage. The source also indexes it as instant.

What the USDA adds in words
The USDA attaches 3 handling notes to this item, reproduced below word for word. None of them is a storage time: they qualify the figures above rather than replacing them. These are the source's own sentences, not ours, and they are the part of the FoodKeeper record that a table of durations cannot carry.
Potatoes, in the freezer. Freezer timeline applies to cooked and mashed potatoes.
Potatoes, in the refrigerator. The United States Potato Board notes refrigeration can cause potatoes to darken during cooking and to develop an unpleasantly sweet taste.
Potatoes, in the pantry. This is the recommended storage method for whole potatoes.
Can you freeze potatoes?
Yes. The USDA gives potatoes 10–12 months in the freezer, and held at 0 °F food stays safe beyond that: the figure is about quality. Most produce goes soft when thawed, so frozen it suits cooking, smoothies and sauces rather than eating raw.
How to tell if potatoes have gone bad
Go by the date first: potatoes keep 1–2 months in the pantry. Mold, slime, a sour smell or soft dark spots mean it goes out; firm produce can be saved by cutting 1 inch around a small moldy spot, soft produce cannot. Refrigerate cut or peeled produce within 2 hours.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 1 month to 2 months in the pantry. The USDA rating this place at all is the USDA saying Potatoes keeps there, so the figure rates how good it will be. Past it, whether it has gone bad is yours to judge by look and smell: this window rates quality, not the day it turns hazardous.
It is past the date. Now what?
Say the calculator above puts Potatoes past its 1 month to 2 months in the pantry window. Past that the calendar stops deciding and the food itself does. Mold, a slimy or sticky surface, soft or darkened spots, or a sour smell mean it goes out whatever the date says.
The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.
Two places, and one of them is the wrong one
The USDA rates two places for Potatoes in one state and they disagree: 1 month to 2 months in the pantry against 1 week to 2 weeks in the fridge. This page answers with the pantry, the longer of the two. Both figures are the USDA's own, so this is a choice of where to put the food rather than a disagreement about how long it keeps.
The two sides of that multiplier are not the same dish
The 6× multiplier on this page is drawn across a change of preparation: the source's note on the freezer figure reads "Freezer timeline applies to cooked and mashed potatoes". It divides 12 months frozen by 2 months in the pantry from purchase, and those two are not the same dish. A multiplier whose sides are different preparations is worth printing only with the source's own scope note beside it.
Items that behave the same way
All 3 of the 6 items nearest Potatoes keep exactly as long as it does, 2 months, so the ranking around it is a tie rather than an order.
Where these numbers come from
Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.
