Do I need to register my domain name under gTLDs (e.g., .com, .net, .شبكة، .موقع) after I registered it under Saudi TLDs (.sa, com.sa, net.sa, .السعودية, …etc)?

The ccTLD sub-domains (.sa, .com.sa, .net.sa,.السعودية .. etc.) are for entities in Saudi Arabia while gTLDs (e.g., .com, .net, .شبكة، .موقع) are open for entities world-wide. We recommend for Saudi entities to register their domain names under Saudi TLDs (.sa, com.sa, net.sa, .السعودية, …etc) and as under some gTLDs if needed.
