People orbiting the tech industry—and especially folks employed within it—tend to mischaracterize the average person's relationship with their smartphones, laptops, gizmos, and gadgets. No one is more guilty of this than me: after all, it's my job to examine these products under a magnifying glass, sometimes literally.

So when a blockbuster item like a new iPhone hits the shelves, my industry friends and I tend to assume most shoppers are as well versed in iPhone history as we are. This is—as I'm sure you know, since you found your way here—not the case. The truth is, most people have no idea which iPhone they use every single day, let alone the differences from generation to generation.

Here's the good news: Finding out which version of the iPhone you own is a relatively easy, two-step process.

Step 1: Find your iPhone's model number

On the iPhone 7 or earlier, you'll find the 5-digit, alphanumeric model number in fine print on the back case of the iPhone. The model number will begin with the letter "A."

The easiest way to determine which iPhone you're holding is by locating its model number.

For most iPhones, this is as simple as turning it over and looking at the back case of the phone—the model number will be printed towards the bottom along with a bunch of other information. You should be looking for a 5-digit alphanumeric code beginning with the letter "A."

For anyone with an iPhone 8, an iPhone 8 Plus, or an iPhone X, the process is a little more complicated. Turn over any of these newer iPhones—and, in all likelihood, future iPhones that postdate this article being published—and you won't find any of the phone's hardware information.

On newer iPhones, you won't find the model number on the back of the phone. Instead, you'll have to find it via the iOS settings menu.

Instead, you'll need to take a quick dip into your iPhone's settings menu in order to ID your model.

Open your phone's settings, scroll down to "General," then open the "About" section. From here, locate the field that says "Model." As a default, the 5-digit alphanumeric code isn't displayed, and instead, the phone's SKU—which also identifies the storage capacity and color—is listed.

From here, you can do one of two things: You can either Google your iPhone's SKU and see which model shows up in the search results, or you can tap the SKU to reveal the iPhone's 5-digit model number.

Step 2: Use the 5-digit model number to ID your iPhone

Once you've determined your iPhone's model number, you're ready to figure out which version of the phone you're using.

Apple lists all of the iPhone model numbers on its website, but I went ahead and sorted them in an easy-to-read chart so you don't have to scroll through their page.

Simply note your iPhone's model number and cross-reference it with the corresponding model on this list.

iPhone X: A1865, A1901, A1902 iPhone 8: A1863, A1905, A1906 iPhone 8 Plus: A1864, A1897, A1898 iPhone 7: A1660, A1778, A1779 iPhone 7 Plus: A1661, A1784, A1785 iPhone 6s: A1633, A1688, A1700 iPhone 6s Plus: A1634, A1687, A1699 iPhone 6: A1549, A1586, A1589 iPhone 6 Plus: A1522, A1524, A1593 iPhone SE: A1723, A1662, A1724 iPhone 5s: A1453, A1457, A1518, A1528, A1530, A1533 iPhone 5c: A1456, A1507, A1516, A1529, A1532 iPhone 5: A1428, A1429, A1442 iPhone 4s: A1431, A1387 iPhone 4: A1349, A1332 iPhone 3GS: A1325, A1303 iPhone 3G: A1324, A1241 iPhone: A1203

The older the iPhone, the less likely you are to be using it—unless, of course, you're trying to identify the old-looking iPhone you just dug out of a box in your attic.
