It is located in northern and central Asia, from north western China, Mongolia, Russia, Kazakhstan, Azerbaijan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Afghanistan, Iran, and Pakistan. This snake has not been evaluated for conservation globally, but in Mongolia, it is categorized as Least Concern due to its large range and the fact that no decline in population has been detected.
