IDN World Report 2022

Statistics, trends and analysis on the global IDN market with a focus on ccTLDs. The objective of this report is to provide a consistent public resource for anyone interested in understanding current trends in IDNs registrations, adoption and technical implementation characteristics.


  • 79% ccTLDs support IDN registration with a further 4 registries in preparation to launch. 

  • There are an estimated 2.2 million IDN registrations and 1.4 million under ccTLDs and gTLDs respectively

  • Over the 12 months to January 2022, median growth of IDN registrations under national ccTLDs was recorded at 2.5% (sample: 39 ccTLDs).  This rate is slightly less than the previous year (2.8%).  

  • Latin is the most common script offered by ccTLDs in the the sample set. 

  • 18 registries offer both IDN and xn-- form in Port 43 WHOIS and 8 registries offer both the forms in RDAP. 

  • ccTLD registries rate registrar support 3.1 out of 5.  This is a decrease from previous years' score of 3.5

  • Registries rate end user awareness of IDNs at 2.3 (out of 5) -  a decrease from the previous years score of 2.6

Figure 1. IDNs statistics among ccTLDs


While a significant number of ccTLD registries offer IDNs (around 79%), the number of actual registrations is often a tiny fraction of their overall domain holdings. When compared to the combined domain name market, estimated at 363 million domains, IDN domains represent less than 1%.  This may not necessarily represent a failing of IDN registrations but rather reflect how the internet has developed from a Western origins predominantly in Latin script.  None the less, awareness of internationalized domain names need improvement if they are to continue to be a viable option particularly for new and emerging economies. IDN registrations grew at a median rate of 2.5% over 2021 which contrasts to 5.6% among the the top 300 TLDs globally. 


The awareness issue around IDNs is evidenced also by how surveyed Registries in the study score user awareness and registrar support to IDNs.  In 2022, surveyed registries gave an average score of 2.2 out of 5 to how they perceive end-user awareness of IDNs.  Further to this, they rate the support provided by Registrars to IDNs an average of 3.1 out of 5.  These figures need improvement if IDNs are to improve their standing and accessibility for internet users as well as their changes for improved adoption in software applications (the concept known as universal acceptance). 


The research team relies on a variety of sources of data for IDNs: ccTLD data is collected directly from the ccTLD registries, both through the regional ccTLD organisations and via direct contact with the individual registries; gTLD data is collected via an external source ZookNIC. 

Working in close partnership with the regional IDN organisations – CENTR and APTLD – the research team circulates two forms -- IDN Implementation and IDN awareness every year in January to the ccTLD registries who are members of these regional organisations. The data collection period generally runs from January to March and allows ccTLD registries to add or update their data on the IDNs implementation characteristics, registration statistics (eg. total IDN domains) and a sentiment survey asking question on their views on IDN adoption and support in their communities. The research team follows up with individual registries on any queries or to fill gaps in the data.

While we aim to reach as many ccTLDs as possible, we cannot reach everyone.  For this reason, the statistics in the report should be interpretated as estimates only.  Given the limitation of input data, we also take care to present data fairly.  For example, statistics on growth in registrations use medians rather than combined absolute growth in order to give a better representation of an average ccTLD.  If you have any questions or suggestions about this report please contact
