Hi @lidatrade. Thanks for being part of GoDaddy Community! It's no small task to start your own domain registration service. Most often, if someone wants to do this, they partner with an existing registrar and become a reseller of their products. GoDaddy does have a reseller program, but our platform does not currently support the languages spoken in Iran. There are other reseller providers that you might be able to work with, but I wouldn't be able to provide you with any suggestions on who to use.
The alternative is to become a registrar yourself, which may be even more difficult. For more information, you can review this ICANN page.
