If you have never had a paid developer account your provisioning profile is only good for a week. This period used to be 30 days but was downgraded to a week sometime in mid-2016, if my recollection is correct.

Apparently if you have had (or currently have) such an account, the period is longer.

You also can't use all the features of the platform, see the "Apple Developer" vs. ADP columns on https://help.apple.com/developer-account/#/dev21218dfd6.
