Praise be to Allaah.
If you take of it yourself and give it directly to one who is entitled to it according to your understanding, then you will be sure that it has gone to the right place. If you agree to give it to someone whom you trust to dispose of it in the manner prescribed in Islam, this is also permissible.
Fataawa al-Lajnah al-Daa’imah, 9/457
Shaykh Ibn Baaz said: If the people who are doing that are trustworthy and honest, and will dispose of the zakaah in the ways prescribed in sharee’ah, then it is OK to give one’s zakaah to them, because this is a way of co-operating in righteousness and piety.
