Hi @Jougito, this limitation is deliberate. Certificate authorities are only permitted in include subject information whose correctness they can verify. Let’s Encrypt has no way to verify these other facts about a certificate applicant and so is not allowed to include them in the certificate.
Although it might be possible to set up a system that would allow verifying people’s country or organizational identity, it’s not clear that it could be done in a fully automated way. Being 100% automated is important for Let’s Encrypt because that’s how we’re able to issue certificates at no charge.
If you need a certificate that includes these fields, you might want to look at other certificate authorities that issue Organization Verification (OV) certificates – something that Let’s Encrypt doesn’t do.
