Letting everyone know who you are certainly matters to some people, else they wouldn't throw the label in front of the word 'charity'. It's often used as a form of advertising, sadly.
I knew a friend named Charity. She helped youth with drug addictions and homeless youth. She gave scholarships and wanted to give one to me but I turned it down. She has AIDS and this was how she gave back to the community of African Americans who need help from their peers. Her name was an idol for many and they put her story in local newspapers. I remember her story and she rented an old office to set up everything she needed. I don't know where she is now but she is traveling. She texted me couple of years ago but didn't keep in touch.
My Buddhist initiation name, for lack of better words,
Phò thiện hạnh (Kind Virtue), is important even though it's common. We say our given names rather than our birth name everytime we go to the temple. I wouldn't doubt it's extremely important for those who receive their initiation name when they have better relations with the head master.
In Deaf culture, instead of finger-spelling their names, they have name signs that relate to their character within the community. In Christianity, Judaism, and Islam, names are extremely important.
Even gender. I asked one time what if Christ was female, and they almost had a hissy fit.
To each his own, I guess.
