As there are more than 150,000 names just in the United States, your middle name helps us verify it's really you!
For example, let's say your name is Jennifer Elektra Smith. That helps us differentiate you from Jennifer Gamora Smith and Jennifer Mystique Smith.
Similarly, if your name is Usain Thunder Bolt, we'll know you're not the Usain Bolt
Don't have a middle name? Don't worry! Just leave it blank.
