Important: You must provide your sample in and return your collection kit from the same country listed on your order.
Each collection kit comes with a prepaid shipping label affixed on the bottom of the box. Before preparing your sample for shipment, make sure to register your kit and replace the funnel lid with the screw-on cap. Your saliva sample is stable at a wide range of temperatures once it is mixed with the DNA stabilization buffer liquid, but we recommend that you ship your collected sample to the laboratory at your earliest convenience.
The transportation supplies for your saliva sample are included in your kit. Simply place the collection tube containing your sample in the plastic specimen bag, and then place the bag directly into the box. The plastic clamshell should be discarded. Remove the adhesive strip on the kit flap and seal the kit.
Drop the package off at any US Postal Service mailbox. The box is already pre-addressed and prepaid. We do not recommend taking your sample to a mail center as the representatives may not be familiar with our shipping materials and may erroneously charge extra fees.
If you have misplaced or discarded the return shipping supplies, please let us know by contacting Customer Care; we will provide you with free replacement shipping materials. Only samples returned with the prepaid shipping materials provided by 23andMe will be processed.
Note: To protect the privacy of all customers, the lab will only accept samples delivered via postal service or carrier. Do not attempt to drop off your sample directly at the lab.
A return tracking link will be available from the sample status progress bar on your profile homepage.
