The release of the Xiaomi 12 series nears, with Xiaomi expected to unveil at least the Xiaomi 12 this month. Typically, the company launches new flagship smartphones in China, as it did last year with the Mi 11. Not all devices make it out of Xiaomi's home market though, such as the MIX 4.
In that vein, Xiaomi has certified two Xiaomi 12 series devices with the TENAA in China, one of the regulatory bodies that Xiaomi must submit its devices to before it can sell them in the country. As the screenshots below show, the TENAA has certified 2201123C and 2202211C, both China-exclusive smartphones. The 2202211C has passed through the 3C in China as well, supposedly with 120 W charging.
However, Xiaomi has also certified the 2201123G with the Eurasian Economic Commission (EEC) in Russia. Based on recent rumours, it would seem that '2201123' is the Xiaomi 12, which will utilise Qualcomm's Snapdragon 8 Gen 1 SoC. @yabhishekhd asserts that '2201123' will launch with Android 12 as well, although it would be more unusual if Xiaomi unveiled a new flagship with Android 11.
@yabhishekhd adds that 2202211C is the Xiaomi 12 Pro, albeit without evidence that supports this. Previously, the Xiaomi 12 Pro was thought to be the 2201122C and 2201122G, rather than the 2202211C. Either way, the 2202211C should be another member of the Xiaomi 12 series and it could be one that the company announces this month.
