Support for IDN TLDs

WHMCS John shared this idea 4 years ago

At present WHMCS can check availability for IDNs on standard TLDs such as ,com, .net and .org.

Please add the ability to also check the availability of Internationalized country code top-level domains, such as:

.中国 (encoded as ".xn--fiqs8s") and .中國 (encoded as ".xn--fiqz9s"; ".zhongguo")

.香港 (encoded as ".xn--j6w193g"; ".hongkong")

.台灣 (encoded as ".xn--kpry57d") and .台湾 (encoded as ".xn--kprw13d"; ".taiwan")

We have some domains under .no with Norwegian letters like ø, æ and å. NORID who is responsible for the registry use the ACE format for their domains (https://teknisk.norid.no/en/registrar/soknad/verktoy/ace/ace_technical/).

We are using DirectAdmin, and since WHMCS do not support IDN/ACE, we have to change the domain names manually to the ACE format before activating new hosting accounts. We like to see this support in WHMCS, so the domain can be stored in original format in WHMCS, and all request sent to DirectAdmin and the domain name registrars is done in the correct ACE format.


There are special TLD cases that require IDN translation to follow IDNA2008 and others to follow IDNA2003.

That would be an important point to consider when implementing it.


Hi all,

I'm pleased to announce that in v8.0 we have improved International Domain Name support. Enom and ResellerClub support automatic IDN registration, and you'll benefit from robust IDN validation and usability improvements.

Please test it out, and let us know your feedback during the pre-release period.
