Global Entry is a program which allows participants a “fast track” through Immigration and Customs when returning to the US from a foreign country. Global Entry also gives participants access to TSA Pre-check(see below).

TSA Pre-check is a program that allows participants flying on participating airlines to use a special line that expedites clearing the TSA “security” checkpoints at most, but not all, US airports.

To clarify, if you enroll in Global Entry you’ll automatically get TSA Pre-check. If you enroll only in TSA Pre-check you DO NOT automatically get Global Entry.
