Additionally, Apple recently submitted a Russian-language filing with the Eurasian Economic Commission (EEC) that seeks to register 11 separate iPhone models.
It's common for several model numbers to correspond with one iPhone, so it's likely that Apple isn't actually planning to release nearly a dozen new devices.
But many believe that the filing, which was first spotted by French site Consomac, gives credence to recent rumors that Apple is looking to release an iPhone SE2.
The SE hasn't been refreshed since it was first released in March 2016.
Since then, it has risen in popularity, at one time topping the charts in the UK as the best-selling smartphone in the nation.
Unlike Apple's other iPhones, which continue to be upgraded in price and design, the SE has a 4-inch screen and starts at US$349.
According to the filing, the model numbers are A1920, A1921, A1984, A2097, A2098, A2099, A2101, A2103, A2104, A2105 and A2106.
They're all Apple-branded and run iOS11, the filing noted.
The A19, A20 and A21 models could also suggest that Apple will release a few different SE models with variations in screen size, camera or other features.
Filings serve as a pretty good predictor for Apple's product pipeline.
Previous EEC filings showed Apple had registered two new iPad model numbers and, low and behold, the firm released two new cheap 9.7-inch iPads.
Rumors suggest that Apple will release the iPhone SE2 at its Worldwide Developers Conference in June.
At the same time, Apple could be planning to launch a follow-up to the iPhone X that features a massive screen.
Kuo believes Apple will release an iPhone with a 6.1-inch edge-to-edge screen that can support two SIM cards and could be priced as low as US$650.
Another 6.1-inch model would only support one SIM card and would be even cheaper with a price tag of US$550.
By comparison, the iPhone X has a 5.8-inch screen and costs US$999.
The 6.1-inch version would also feature an LCD screen, instead of the iPhone X's pricier OLED display.
