The organization headquarters was located in Warsaw at 24 . Żegota was active chiefly in Warsaw, but it also provided money, food, and medicines for prisoners in several forced-labor camps, as well as to refugees in Kraków, Wilno (Vilnius), and Lwów (L'viv). Żegota's activities overlapped to a considerable extent with those of the other major organizations dedicated to helping Jews in Poland – namely the Jewish National Committee, which cared for some 5,600 Jews; and the "Bund", which cared for an additional 1,500. Together, the three organizations were able to reach some 8,500 of the 28,000 Jews hiding in Warsaw, and perhaps another 1,000 hiding elsewhere in Poland.
