Is it permissible to give Zakat to charitable organizations or individuals who collect donations online without verifying their credibility?

One must be careful when paying Zakat, and it should only be paid to those known or strongly presumed to be among its rightful recipients. If you know or strongly presume that they are among those entitled to Zakat, there is no harm in paying it to them. It is not obligatory to pay it to the Zakat fund designated by the state. The ruling on paying Zakat to a beggar whose situation is unknown and the categories of Zakat recipients have been previously discussed.
