    Question How to find which 23andMe chip version used?

    Other than examining headers in downloaded raw data, etc, is there a straightforward/easy way for a 23andMe customer to determine if they were tested with the V2 or the V3 chip?

    I'm trying to help a non-technical person with this question via email.

    Once signed in, be on the Home page.
    At the bottom of the Home page, find About"and then click on "Site map".
    Then, find "Where to buy"and then click on "Existing customer platform updates".
    The answer should be there, if you get a message that says "updating to the current platform currently unavailable"you have the most recent one before the one that started scrubbing the health data from.

    I'm not sure that method is 100% reliable. I just tried it and I got the message "Updating to the current platform is presently unavailable" but I was tested with the V2 chip.

    Distinguishing of V3 vs V2/V4 is easy, you can use genome comparison tool since it shows total SNPs i.e. V3 900K SNPs and V2/V4 around 500K..
    V4 vs V2 is tricky, I can't say anything for sure but I see V4 is 570K ballmark and V2 550K, though I don't have enough samples to observe the respective ranges..

    Thanks, but I'm trying to avoid having to deal with the raw data.

    I'm getting the impression there isn't a straightforward way to determine this matter. I'd ask 23andMe except that they make it difficult to contact them.

    I may be able to use testing date as a guide. Does anybody recall when the V3 chip was introduced.

    Okay, I asked on 23andMe Community and received this very useful tip for the record:

    Go to Gene Comparison, and compare yourself to yourself in "one to one". See how many SNPs are given as the total. If it is around 900 thousand then its the V3 chip.

    I did this with my V2 data and got 555,564 SNPs, so that's a quick and easy technique for determining V2 vs V3, which was my aim.

    And I'm advised that the date of introduction of the V3 chip was around November 2010.

    Great, thanks! Mine says 956112 SNPs, but I knew I had V3 but it's nice to know how to find it for someone.

    OK, I'm having a problem navigating the page.

    Where do I find "Gene Comparison" again? I need to see if I can transfer my cousin's data for FTDNA's free upload.
