The custom name you gave an Apple device won't identify its hardware. For support or accessories, MacMost recommends finding the official model name and its exact number.
On a Mac, Apple menu > About This Mac gives the type, model, and year. The chip and memory can matter for specific hardware or app requirements, but MacMost says the macOS version is often the first compatibility check. For more detail, the tutorial points toward System Settings; Apple's System Information also lists a model identifier and part number when the displayed name isn't specific enough.
On iPhone and iPad, open Settings, then General, then About. That screen shows the Model Name and a Model Number field; Apple's guide says tapping the part number reveals the device's A-number. That small step helps iPhoners ordering a case for an older iPad check an accessory's compatibility against the exact hardware, while an app's requirements may call for the OS version instead. For a case, compare that A-number with the seller's compatibility list before ordering.
