Default how long does dry yeast last?

So I got a Midwest recipe kit in the mail. I took the yeast out and stuck it in the refrigerator. Then, a week later, I found that they had put another yeast packet in the kit (apparently by mistake)...it was a Safale US-04 packet. I quickly put the yeast in the fridge, but can yeast survive that long?

I store my dry yeast in the fridge, but it doesn't need to be stored in the fridge. My LHBS sells it off the shelf. I've used two year old yeast that sat at room temp and it worked just fine.

Should have an expiration date stamped on it too.

My LHBS sells it off the shelf too. So I keep my Notty on my shelf as well. Works just fine.

Unless, of course, you're going to keep it for a year or so like that. Then you'll just have to use it for yeast nutrients in the boil.

Most better stores store all their yeast, wet or dry in the fridge. I keep mine in the fridge and have used yeast over 2 years old and it has been viable.
