Which city code is 496?

Did someone call you from a completely unknown number? What kind of code is 496? What city phone numbers start with it?

These figures belong to the cities of the Moscow region. However, there is one nuance, from September 2012, the transition to 10-digit phone numbers was completed. In this connection, a part of the regional city numbers changed the code. So, for example, the cities of the Leninsky and Krasnogorsk districts of the Moscow region now have the code 495, as the above-mentioned territories became part of the "big Moscow".
