What is GEDmatch?

Upload your DNA file To GEDmatch
To begin, you must register on GEDmatch.com
First, upload your DNA data file from DNA testing companies like AncestryDNA. After receiving the test results, these companies allow you to download your own raw DNA data file (usually a zip file) and upload that elsewhere to access different information, like GEDmatch.
List of companies whose raw data are compatible with GEDmatch (links to respective pages explaining how to download raw DNA data):
AncestryDNA (Ancestry.com)
23andMe
MyHeritage
Family Tree DNA (FTDNA)
LivingDNA
GEDmatch now claims that “most other” online DNA testing service's, files are also compatible with their system!
Once you’ve downloaded your raw data file, create a GEDmatch account and upload your raw DNA data. (We’re writing a step-by-step guide on how to do this in another blog post). Note that it will take a few hours after uploading to see your results. They don’t notify you when it’s ready — but you can check the “Kit ID”, and if it says no kit number registered yet, you need to wait a little longer.
What Is a Kit Number
On GEDmatch? After you upload your raw DNA data file for DNA analysis, the company will assign you a kit number. Your kit number is a unique identifier tied directly to your DNA profile on GEDmatch. Your kit number will allow you to share your profile with friends and other members on GEDmatch and in our private FB Groups. Comparing your GEDmatch DNA kit number to others in our FB groups allows you to connect to your DNA matches in a group that loves to share and help solve walls using DNA!
Kit numbers have a standardized format, which also allows you to see where certain sources of data come from. This is useful if you are trying to track down relatives, as you will get the best results if you submit a DNA data from the same source because the exact same sites will be tested. This will give you the most accurate results.
