Download your raw data
Sign in to 23andMe
In the top right corner, click on the down arrow ("V") next to your profile photo and name. In that drop down menu, click on "Browse Raw Data".
On the next page, you'll see two tabs "Browse" (current tab) and "Download". Click on the "Download" tab. Scroll down the page until you reach the "Request your raw data download" section. Read the statement and click the box next to "I understand the limitations and risks associated with uploading my information to third party sites." Click "Submit request".
The next screen will say: "Your download request is in progress". Check the email associated with your 23andMe account for the next step.
The email should arrive within a few minutes. Open the email and click "Download Raw Data". This will redirect you back to 23andMe where you can download the file. On that page, click on the blue "Download raw data" button on the page and you'll get a pop up asking where to save the .zip file. Save the file to your computer where you can easily locate it again but don’t open it or unzip it. You’ll need it as-is to upload to GEDmatch.
How to upload to GEDmatch
Go to GEDmatch and make an account. Check the email address that you just used to register, and click the link in your email to confirm your registration.
Now return to GEDmatch, and log in with your email address and password.
On the main page of GEDmatch, there will be some announcements at the top and two columns of links below those. In the gray box in the right column, you will find a section that is entitled "Upload your DNA Files." Below this title, click on "Generic Uploads (23andme, FTDNA, AncestryDNA, most others)."
Fill in your information "Name of Donor" is the name of whomever the DNA data comes from originally. This is to be that person's legal name. If you leave the "Alias" field blank, this will appear to other DNA matches on the site. If you enter an alias, this will be shown instead of your legal name.
"Sex of donor" is a field that is visible to other testers in the one-to-many results. If you are transgender, intersex, nonbinary or any other expression, you can select whatever best represents you and it will not impact the way your DNA is handled by the database.
In the "Company or source" dropdown, select "23andMe."
In the section of the form that begins "When you upload Raw Data to GEDmatch, you agree that the Raw Data is one of the following (select one):" you will most likely be selecting one of the first four options:
DNA of a person for whom you are a legal guardian
DNA of a person who has granted you specific authorization to upload their DNA to GEDmatch
DNA of a person known by you to be deceased
Select the correct response and continue to the next section, which is the most important part if you want to help forensic genealogists! Choose Opt-in to be visible in the public database to all other testers and for comparison with kits used for law enforcement investigations.
At the bottom of the page, there are two buttons. the left one says "choose file." click this button and select the file you downloaded from Ancestry. Then click the button on the right marked "upload". Wait a few minutes. When the file is done uploading and processing, you'll see a big red number. This is your kit number on GEDmatch. the instructions say to "Write this number down," but don't worry - this number will be visible on the main page whenever you log in to GEDmatch so you won't lose it.
Your kit won't be available for everyone to see in their one-to-many lists for a day or two, but if you already know the kit number of someone else you want to compare yourself to, you can use the one-to-one features right away.
If you uploaded your kit because you were asked to by a forensic genealogist, please send a message to the genealogist who asked you and give them your kit number. They won't be able to give you the kit numbers of any active forensic cases, but they will be able to compare your kit to theirs to see if you're a match!
