There have been about 51 different iPhone models released so far, from the original 2007 iPhone up through the iPhone 17 lineup and related variants like SE and Air models.

What “how many iPhones are there” can mean

People usually mean one of three things when they ask this:

  1. How many different iPhone models exist?
    • Apple has released around 51 distinct models (counting minis, Plus, Pro, Pro Max, SE, Air, etc.).
 * These span roughly 24 “generations” of iPhone (iPhone, 3G, 4, 5, … up to 17).
  1. How many iPhones have ever been sold?
    • By mid‑2025, more than 3 billion iPhones had been sold in total.
  1. How many are actively in use today?
    • Estimates in 2025 put active iPhones at over 1 billion devices worldwide.

Here’s a quick view in HTML table form, as you requested:

If you tell me whether you meant “models,” “sold ever,” or “in use right now,” I can narrow it down even more.
