Where to find us

GSTC is a “virtual” organization, and truly global. We do NOT have a main office. Our staff, Country Representatives, Board members, Working Group and Committee members, and volunteers work from various locations around the world.

Therefore we prefer information sent to us digitally.

If you must post/mail printed material to us, PLEASE NOTE: we use a digital service to scan materials which cannot accept magazines or other bound material; and you must provide the address precisely as indicated below:

P.O. Box 96503 #51887
Washington, DC 20090-6503 USA

To repeat, please email us if possible, and only send printed material if necessary.
