Before you get too excited from the title — no, this does not mean the iPhone 13 is coming early.
Apple is typically required to file their devices in regulatory databases way ahead of launches, and Consomac was able to spot new model identifiers added to the Eurasian Economic Commission.
The devices are listed as A2628, A2630, A2634, A2635, A2640, A2643, and A2645

All iPhone 13 models are expected to launch this fall, as normal, with no delays like the previous year.
