Wondering what happens to all those letters that kids send to Santa every year? In San Francisco, they all end up in one mailbox—and those from children in need get special attention.

The ‘Letters to Santa‘ program connects volunteers with children who need basic necessities, such as clothing, shelter, or food. These letters from children are available for volunteers to review in the customer lobby at the San Francisco Processing & Distribution Center, at 1300 Evans Ave. in San Francisco on the following days:

Thursday Dec 1, 11 a.m. to 1 p.m.
Tuesday Dec 6, 11 a.m. to 1 p.m.
Thursday Dec 8, 11 a.m. to 1 p.m.
Tuesday Dec 13, 11 a.m. to 3 p.m.
Thursday Dec 15, 11 a.m. to 1 p.m.
Tuesday Dec 20, 11 a.m. to 3 p.m.

To protect the children’s identities their addresses will not be listed. Instead, volunteers who have selected wish lists to fulfill will pass off their packed gift to the Postal Service, who will make sure it gets where it’s going.
