How to tell if it is C or S on your iPhone 5?

Someone asked me how can you find it, I told him, I have no idea.
So, can you tell me how to how to find it in my iPhone 5?

The iphone 5s is not plastic. The iphone 5c is plactic. Hope this helps.

5S is aluminum and has fingerprint scanner… Pretty easy to tell a difference.

The 5, 5c & 5s are 3 distinct iPhone models. Not something found on an iPhone 5.

The 5c looks like

The 5s looks like

The 5, 5c and 5s are all quite similar (shape, screen size, etc.). I think they say the model on the back of the phone (at least I think my iPhone 5 does, but I'm not going to take it out of its case to verify). The 5c does not (my teens just got these phones).

if your phone has a fingerprint scanner, it is the 5s. The 5 and 5c do not have that feature.

If the phone is colorful (blue, green, yellow, pink) It is a 5c. However, the 5c also comes in white and so does the 5 and 5s so if it is white you can't tell by color.

If the phone has a plastic casing, it is a 5c.

Read the model number from the back, Genius.
