Questions people ask before buying .si
Can anyone register a .si domain?
Yes. ARNES (the Slovenian registry) does not require residency or a local contact. Your contact details must match your ID documents, an EU security rule (NIS2) — and privacy protection is not offered, which is normal for .si.
Is .si really the “new .ai”?
It is the pragmatic alternative, not a clone. The same short name often costs a fraction on .si, renewals are cheap, and “si” reads as superintelligence to a technical audience. It is a ccTLD, so it signals Slovenia first and AI second.
How accurate is the appraisal?
It is a range with a confidence level, anchored to real .si sales. With two or more comparables it is directionally useful; with none it is a rough placeholder and we say so.
How do I sell a .si name here?
