I currently live in an area which does not have a Jewish community, let alone a lab for checking shatnez. Is there a reliable place in which I could send my clothing to check for shatnez?
The Flatbush Shatnez Center can be contacted at 718-382-5689. You can ship your garments to them and they will ship it back to you.
You should call them first as they will guide you as to which articles of clothing need to be sent. Certain clothing may not need to be inspected and certain brands they can tell you from experience that it does not require inspection.
