The Apple iPhone 12 launched in 2020 as the first mainstream iPhone built for 5G, and it introduced the flat-edge design language Apple still uses today. It shipped as A2172 across AT&T, T-Mobile, Verizon, and fully unlocked units in the US, with an A14 Bionic chip, dual-camera system, and Ceramic Shield front glass. It was aimed at anyone wanting a compact, capable everyday phone without paying for the Pro camera system, and it still holds real resale value because the design, chip, and OLED display have aged well. Pick your storage and carrier in the configuration picker above, choose the condition that matches your phone, and you'll see a live cash offer instantly. If you want the mechanics first, you can see how the process works, or head straight to the page to sell your iPhone.

Confirm you have the iPhone 12

Open Settings → General → About and check the Model Name field, which should read "iPhone 12." Tap the Model Number field to toggle from the regulatory code (starting with M) to the internal model number, which should show A2172 for a US unit. The regulatory code narrows down carrier and region, so if you're not sure which one you have, either number confirms this is the right phone.

A2172 (US, all carriers)

  • Used for AT&T, T-Mobile, Verizon, and unlocked units sold in the US
  • Regulatory codes vary by carrier and storage: MGEK3LL/A, MGEV3LL/A, MGF23LL/A, MGEF3LL/A, and others in this family
  • All A2172 units support the same carriers once unlocked

Prefer a visual check? The iPhone 12 has flat aluminum sides, a single-lens camera bump housing two lenses stacked vertically, and no third camera or lidar sensor on the back. The back glass is a single flat pane, not the frosted matte finish used on the Pro models.

Battery, build & more

Battery. Non-removable and not user-replaceable. Battery health degrades with age and charge cycles, so a phone with strong reported health typically brings a higher offer.

Finishes. Aluminum frame with glass back, offered in black, white, red, green, and blue.

Software. Originally shipped with iOS 14 and has continued receiving iOS updates for several years, which keeps it usable for everyday tasks.

Market positioning. Sits below the iPhone 12 Pro in Apple's original lineup, with a matching design but a simpler camera system, which puts it in the mid-tier resale bracket for this generation.

Frequently asked questions

01 How do I find the model number or exact configuration?
Go to Settings → General → About. The Model Name field reads "iPhone 12," and the Model Number field shows a regulatory code starting with M; tap it to reveal the internal number, A2172 for US units. The same screen lists storage capacity under the Capacity field, so you can match it to the picker above. If your phone won't turn on, the model number is also printed in small text on the SIM tray or original packaging.
02 How do I tell it apart from the iPhone 12 Pro?
Check the back camera and the frame material. The iPhone 12 has two rear lenses and a matte aluminum frame, while the iPhone 12 Pro has three rear lenses plus a small lidar dot, and a shiny stainless steel frame. The 12 Pro's back glass also has a matte, frosted texture, while the iPhone 12's is glossy and smooth. If the camera bump shows only two lenses, you have the standard iPhone 12.
03 Can I sell it with damage, a weak battery, or a locked account?
Yes, in most cases. Cracked screens, weak battery health, and phones that won't power on can still qualify for an offer, adjusted for condition once the device is inspected. What can't ship is a phone still tied to an Apple ID: Find My iPhone and Activation Lock must be removed before you send it in, since a locked phone can't be tested or resold. Sign out of iCloud from Settings before shipping to avoid delays.
04 What raises the trade-in value the most?
Being unlocked and carrier-free helps first, since it widens who can use the phone next. Beyond that, a screen and back glass free of cracks, strong reported battery health, all original functions working (Face ID, cameras, speakers), and the original box or charging cable all move the offer upward. Higher storage tiers, like 256GB, also carry more value than 64GB units of the same condition.
05 How do I erase it and get paid?
Back up anything you want to keep, then go to Settings → General → Transfer or Reset iPhone → Erase All Content and Settings. Confirm you're signed out of iCloud and that Find My iPhone is off, since a locked device can't be processed. Once your quote is confirmed, shipping is free and insured, and payment goes out after testing by PayPal, Venmo, Zelle, CashApp, or check.
