The freezer is the shorter option here
Here the freezer is the shorter option, not the longer one: 8 months in the sealed pantry against 4 months frozen, 2 times less. That is the reverse of what the freezer usually does, and it is the one thing about this item worth remembering. On the same shelf it sits 54 of 70, between Granola at 9 months and Almonds at 8 months. Cracker in the source list is this same food.

Can you freeze crackers?
Yes. The USDA gives crackers 3–4 months in the freezer, and held at 0 °F food stays safe beyond that: the figure is about quality. Freeze it well wrapped while it is still well inside its fridge window: the freezer keeps quality, it does not restore it.
How to tell if crackers have gone bad
Go by the date first: crackers keep 3–4 months in the fridge once opened. A sour or off smell, mold, slime or an odd color mean it goes out. The bacteria that make people sick change none of these, so past its window it goes out even if it seems fine. Never taste to test.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 3 months to 4 months in the fridge once opened. What decides that is the food and not the shelf the source files it on: Crackers is acid, dry, sweet, alcoholic or pure fat. 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 Crackers past its 3 months to 4 months in the fridge once opened window. Past that the calendar stops deciding and the food itself does. A rancid, paint-like smell in a nut, an oil or a seed, mold around the neck of a bottle, or a swollen can 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 Crackers in one state and they disagree: 3 months to 4 months in the fridge once opened against 1 month in the pantry once opened. This page answers with the refrigerator, 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.

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.
