Can I Register a .CO Domain With Special Characters?
Yes. You can register .CO domains using Internationalized Domain Names (IDNs). This allows you to include special characters and letters from different alphabets, making your domain better match your language and brand.
Supported Languages
At this time, .CO domains support IDNs in the following languages:
- Chinese
- Danish
- Finnish
- French
- German
- Hungarian
- Icelandic
- Japanese
- Korean
- Latvian
- Lithuanian
- Norwegian
- Portuguese
- Russian
- Spanish
- Swedish
Future Language Support
Additional languages are being reviewed and may be added later.
Official language policies are available in the .CO IDN policy guide.
More details can also be found through IANA’s IDN Repository.
Key Takeaway
If your preferred domain includes special letters (like accents, umlauts, or non-Latin scripts), you can register a .CO IDN in many European, Scandinavian, and Asian languages, with more to come in the future.
