The Apple iPhone 17 Pro launched in 2025 as Apple's high-end camera-and-performance flagship, built for people who shoot photo and video seriously, edit on the go, and want a phone that stays fast for years. It carries model number A3256 in the US, alongside regional variants like A3523. Because it sits at the top of the lineup with a Pro-grade chip and camera system, it tends to hold resale value longer than standard iPhone models, especially in higher storage tiers. Pick your carrier, storage size, and condition in the picker above and you will see a live cash offer instantly. If you want to see what happens after that, see how the process works, or head straight to the sell your iPhone page to compare it against other models before you commit.

Confirm you have the iPhone 17 Pro

Go to Settings → General → About and check the "Model Name" field first. Tap "Model Number" once and it toggles from the order number (starting with M) to the regulatory model number (starting with A). Both are useful: the order number tells you the exact storage and carrier configuration, and the regulatory number confirms the hardware generation.

Software

Ships with iOS 26 and receives ongoing iOS updates for several years, which is part of why Pro models age well as resale candidates.

Accessories

Market positioning

Premium tier within the current iPhone lineup. Higher storage configurations and carrier-unlocked units tend to command stronger resale interest than carrier-locked, lower-storage units.

Frequently asked questions

01 How do I find the model number or exact configuration?
Go to Settings → General → About and look at "Model Name." Tap "Model Number" once to switch between the order number, which starts with M and identifies your exact storage and carrier combination, and the regulatory model number, which starts with A. If the phone will not power on, the same A-number is stamped on the SIM tray. Either number is enough to confirm you have an iPhone 17 Pro and not a different generation.
02 How do I tell it apart from the standard iPhone 17?
Look at the rear camera housing first. The iPhone 17 Pro has a wide plateau spanning the full width of the back with three visible lenses, while the standard iPhone 17 has a smaller two-lens module. The Pro also has a Camera Control button and Action button on the side, a textured matte back finish, and a slightly larger, brighter ProMotion display. If the case obscures the back, Settings → General → About will settle it immediately.
03 Can I sell it with damage, a locked account, or a weak battery?
Yes, in most cases. Cracked screens, degraded battery health, and phones that won't power on can still be sold, and the condition picker above accounts for this. What cannot ship is a phone still signed into iCloud with Find My enabled and Activation Lock active, since that makes the device unusable to anyone else. Sign out of iCloud (Settings → General → Transfer or Reset → Erase All Content and Settings will prompt this) before you send it in. If the phone is under contract or tied to a corporate account, check with your carrier or IT department first.
04 What raises the trade-in value the most?
Storage tier and condition move the offer the most. A 1TB unit in excellent condition will always quote higher than a 256GB unit in the same shape. An unlocked phone typically draws more interest than one locked to a single carrier, since it can go to more buyers. Beyond that, an intact screen, healthy battery, original box, and removal of all account locks before you submit the order all keep the quote closer to the top of its range.
05 How do I erase it and get paid?
Back up anything you want to keep, then go to Settings → General → Transfer or Reset → Erase All Content and Settings. This signs you out of iCloud and Find My and wipes the device to factory settings. Confirm the SIM is removed if you are keeping your number, and unpair any linked Apple Watch beforehand. Once your order is submitted, ship the phone in free with the prepaid, insured label we provide. After it arrives and passes testing against the condition you selected, payment goes out by PayPal, Venmo, Zelle, CashApp, or check. Full details are on the data erasure protocols page.
