Our PCB fabrication service does not provide tracking information once a package has been shipped, we only know the date it was shipped.
PCB fabrication typically takes two weeks. Shipping takes anywhere from a few days in the US to a few weeks outside the US. Often there is a delay at the customs agency of countries outside the US.
If you have waited more than 3 weeks please contact support via the 123D Circuits help page. Please be specific about your order.
