A quote on your old iPhone is only as accurate as the details you give. Say “iPhone 15 Pro, 256GB” when the handset is actually a 128GB model, and the buyer’s inspection will catch it, forcing a revised offer after you’ve already mentally spent the money.
The fix takes about two minutes. Settings > General > About shows your exact model name, storage capacity, and serial number in one screen, and that single check prevents most of the pricing surprises that happen during resale.
This matters more than it used to. With iPhone generations stacking up year after year (Pro, Pro Max, Plus, e-series, and now Air), model names alone no longer tell you much. Two phones that look identical from across a room can carry completely different chips, storage ceilings, and resale values. Confirming the specifics before you request a quote keeps the number you’re quoted and the number you’re paid in line with each other.
How Do You Confirm Your Exact iPhone Model?
The fastest and most reliable way to answer “what iPhone do I have” is through the Settings app, which displays the model name, storage, and serial number without needing any tools. If the phone won’t boot, the model number stamped on the SIM tray or the back of the device becomes your fallback. Design clues like Camera Control, the Action button, or Dynamic Island can narrow things down but shouldn’t be treated as confirmation on their own.
Where Are the Model Name and Storage Capacity in Settings?
Open Settings, tap General, then tap About. This screen lists the Name, iOS software version, Model Name, Model Number, serial number, and Capacity, according to Apple’s own support documentation.
Capacity refers to total storage (64GB, 128GB, 256GB, and so on), while Available shows what’s left unused right now. Sellers sometimes confuse the two, reporting the GB of free space instead of the actual storage tier. Always use Capacity, not Available, when filling out a quote request.
What Does the Apple Model Number Tell You?
The model number (an alphanumeric code starting with “A”) identifies the specific regional and hardware variant of your iPhone, which the model name alone doesn’t capture. From the About screen, tapping the part number next to Model Number reveals this A-number, and you can hold it down to copy it.
This distinction matters for trade-in accuracy. Apple’s identification page lists, for example, that the iPhone 17 Pro carries model number A3256 in the United States and Puerto Rico, while other regions use A3522, A3524, or A3523 depending on where the unit was sold. The iPhone 17 Pro Max uses A3257 domestically, with separate numbers for other markets. Even within the same model year, Pro and Pro Max variants, and sometimes the same model sold in different countries, carry different A-numbers tied to radio bands and certifications.
The serial number is a separate identifier unique to your individual unit, distinct from the model number that’s shared across every unit of that same variant. Keep both handy when requesting a quote: the model number confirms what you have, and the serial number (along with the IMEI) confirms it’s your specific device during verification.
How Can You Identify an iPhone That Won’t Turn On?
A dead or disabled iPhone can still be identified through its physical model number. On most recent iPhones, that number is etched on the back of the housing or printed on the SIM tray, and in markets where a physical nano-SIM card tray still exists, the model number often appears right on the tray itself, as noted in Apple’s iPhone identification guide.
If the housing markings are too worn to read, check original packaging. The box label typically lists the model name, storage capacity, and serial number exactly as they appeared when the phone was new. An account record from your carrier or Apple ID purchase history can also confirm the configuration if the box is long gone.
Which Design and Hardware Clues Help Narrow Down the Model?
Physical features can narrow your search but rarely confirm an exact model by themselves. The presence of Camera Control, a Dynamic Island, a LiDAR Scanner, an Action button, or a USB-C connector tells you roughly which generation range you’re in, since these features were introduced and carried forward across specific years.
For instance, Apple’s documentation describes the iPhone 18 Pro Max as having a 6.9-inch display with a smaller Dynamic Island, an aluminum unibody with Ceramic Shield, Camera Control on the lower right side, a LiDAR Scanner, and a USB-C connector, with no SIM tray in the United States. The iPhone 17 and iPhone 17 Pro share many of these same elements but differ in camera count and back material. Design alone won’t tell you whether you’re holding a 256GB or 1TB unit, or a Pro versus a Pro Max in a market that uses the same body style. Treat hardware clues as a cross-check against the Settings reading, not a replacement for it.
What Specs Should You Check Before Requesting a Quote?
Beyond the model name, a buyback quote depends on your exact storage tier, IMEI status, and carrier lock state, each of which can shift the offer independently of the others. Confirming these details before submitting a quote request avoids the single most common cause of post-inspection repricing.
Why Does the Exact Storage Tier Affect Your Offer?
Storage capacity is one of the biggest single factors in resale value, and guessing wrong is a frequent, avoidable mistake. A phone with 20GB of free space is not automatically a 64GB model, and having a lot of saved photos doesn’t make it a 256GB unit either, as one guide on checking iPhone model and storage before selling points out. The only reliable figure is the Capacity line in Settings > General > About, not an estimate based on how the phone feels in daily use.
The gap between tiers can be substantial. Recent iPhone lineups span from 256GB up to 2TB on Pro Max models, according to Apple’s model identification page, and quoting the wrong tier means the number you see online won’t match what inspection confirms.
How Do You Check IMEI and Carrier Lock Status?
The IMEI and Carrier Lock status both appear on the same About screen, just below the serial number. Apple’s support documentation confirms that this screen displays the IMEI, EID, and other cellular identifiers, along with Carrier Lock status and network information, and that on supported models the IMEI is also printed on the physical SIM card tray.
A carrier-locked phone, or one with an unclear lock status, typically commands a lower offer than a fully unlocked device, since buyers need to confirm it’ll work across networks. If you’re unsure how to locate yours specifically, a walkthrough on how to find the IMEI number on your iPhone can help you pull that number without digging through menus blind. Confirming carrier status upfront, rather than leaving it for the buyer to discover, keeps your quote closer to the final payout.
Where Do You Find Specs on Android Phones, MacBooks, iPads, and Consoles?
Other devices follow similar but distinct paths. On Android phones, the equivalent screen is Settings > About Phone, which shows model name, Android version, and storage. On a MacBook, click the Apple menu and choose About This Mac for chip, memory, and storage details. iPads use the same Settings > General > About path as iPhone. Gaming consoles typically list model and storage under a system or console information menu in system settings.
Device Type | Where to Check Specs |
iPhone / iPad | Settings > General > About |
Android phone | Settings > About Phone |
MacBook | Apple menu > About This Mac |
Game console | System Settings > Console Information |
How Do Accurate Details Help You Get a Gizmogo Quote?
Accurate model, storage, and carrier details let Gizmogo’s instant quote tool return a number that holds up once your device arrives for inspection. Submitting a vague or guessed configuration is the most common reason a quote gets revised after the fact, since the inspection process simply confirms what Settings already told you.
Before you request your quote, it helps to walk through a complete pre-sale checklist covering data backup, Activation Lock removal, and a factory reset, alongside the model and storage check. Having the IMEI, model number, and capacity written down ahead of time means you can fill out Gizmogo’s form in one pass rather than switching back and forth to your device mid-submission. That small amount of prep is what separates a quote that holds steady from one that needs a second look after inspection.
