How accurate is 23andMe at getting your haplogroup right? Is there a chance my FTDNA YDNA test will be different?

The basic clade will be accurate ,If it gives deeper subclade it'll probably be wrong...

It was very accurate for me, I got the same result for my Y-DNA on both 23andme and FTDNA (also on Wegene + Morley's Y-DNA predictor). However, FTDNA narrowed my mtDNA down to a more specific subclade, so in individual cases I suspect FTDNA might be more accurate for some people.

23andme is accurate and can often give you a deeper subclade than basic str testing at FTDNA; depending on which test you buy. Whats your Y dna and ethnic background?

From what I now know my birth father's family is from northern Germany (schleswig-holstein area) originally. The subclade is R-M167 which the internet tells me is actually Spanish. This seems improbable to me

You mean like "R1b" is right but the more exact subclade R-M167 could be wrong?

Probably something more than R1b I'm not sure ,I base this on the fact that I got G-F82 and I recently found a match with common patrilineal ancestor who got a different one.

VERY ACCURATE. But not that precise

What do you mean by accurate but not precise?

It will not go very deep. Will tell you e.g. R1b DF13 but not any deeper

well it said i was I-L38 and that's from central Germany where my direct paternal ancestors come from

im wondering why my haplogroup from northern Germany is a Spanish one then. I wonder how that happened

23andme does not test for as many SNPs on the y-chromosome as you would get from a full y-dna test. What they do test for is accurate.

For example, 23andme says that I am I-Z58. However, I got my full genome sequenced by Dante Labs and sent the files to yfull, who determined that I am a subclade of I-Z2040 (which I will not specify because there is only one other person in their database who matches right now).

Since I-Z2040 is in fact a subclade of I-Z58, 23andme is accurate. But it is not detailed.
