You’ve probably been there. You are staring at a used iPad on a marketplace like eBay or Swappa, wondering if the "Mint Condition" description is actually a lie. Or maybe you found your old tablet in a drawer and can't remember if it's a 4th or 5th generation model. Most people think they need to be a genius to figure this out, but honestly, you just need that string of digits on the back. To look up iPad by serial number is the single most effective way to verify exactly what hardware you are holding, or about to buy, before you drop any cash.
It is surprisingly easy to get tricked. Apple’s naming conventions are a mess. "iPad Air" could mean a device from 2013 or 2024, and they look remarkably similar to the untrained eye. That serial number is the digital DNA of the device. It tells you the factory where it was born, the week it was made, and most importantly, its legal status.
Where to Find That Elusive String of Characters
Before you can do a search, you need the code. If the iPad still turns on, go to Settings > General > About. It’s right there. You can long-press the number to copy it, which is way easier than squinting at the tiny font.
But what if the screen is smashed or the battery is dead? Flip it over. Apple lasers the serial number onto the back of every iPad in tiny, microscopic print near the bottom. If you have a Pro model with a space gray finish, good luck reading it without a flashlight and maybe a magnifying glass. If the back is too scratched to read, check the original box or the receipt. Apple also lists it in your Apple ID account page if the device was ever synced to your iCloud.

Sometimes people confuse the Model Number (like A2270) with the Serial Number. The model number tells you the type of iPad it is, but the serial number is unique to that specific unit. You want the unique one.
Using the Official Apple Check Coverage Tool
The first place everyone should go is Apple’s own Check Coverage website. It’s the gold standard. You type in the serial, solve a captcha that is usually way too hard for no reason, and boom—info.
Apple’s database will show you the exact model name. It also tells you if the device is still under warranty. This is huge. If a seller says "it has AppleCare+" and the check tool says "Coverage Expired," they are lying to you. It also shows the "Valid Purchase Date." If Apple says the purchase date isn't validated, it usually means the device was never properly activated or might be "white box" stock meant for replacements.
The limitation? Apple won't tell you if it's stolen. They are weirdly private about that. They will tell you if the device is eligible for support, but they won't explicitly flag it as "blacklisted" on this specific page. For that, you have to dig deeper into the activation lock status.
Why a Serial Number Search is Your Best Defense Against Theft
Buying a stolen iPad is a nightmare. You’ll try to sign in, and a screen will pop up saying "Locked to Owner." At that point, you have a very expensive paperweight. You cannot bypass iCloud Activation Lock. Don't believe the sketchy YouTube videos claiming they have "unlock software." They are scams.

When you look up iPad by serial number on third-party sites like CTIA’s Stolen Phone Checker or specialized IMEI/Serial aggregators, you can see if the device has been reported to carriers or police. While iPads are mostly Wi-Fi, the cellular models have an IMEI that is linked to the serial. If that serial is flagged in the GSMA database, it’s toast.
I once saw a guy buy a "sealed" iPad Pro in a parking lot. The serial number on the box looked legit. When he finally looked it up later, the serial was for an iPad Mini. The scammers had printed a fake label and shrink-wrapped an old box. Always verify the serial on the actual chassis, not just the packaging.
Deciphering the Code: The Secret Language of Serial Numbers
Prior to 2021, Apple used a predictable 12-character format. You could actually "read" these. The first three characters represented the manufacturing site. The fourth was the year and half-year of production. The fifth was the week.
- First 3 digits: Factory code (e.g., DLN, G5J).
- 4th digit: The year code.
- 5th digit: The specific week of that year.
Then Apple changed the game. They switched to a randomized 10-character string. Why? Probably to stop people from guessing production volumes or identifying specific "bad batches" from certain factories. If your iPad has a weird, random-looking 10-digit serial, it’s a newer model. If it’s 12 digits, it’s a legacy device.
Knowing the "Refurbished" Secret
While the serial number is great, the Model Number (found in the same Settings menu) tells a different story. If the model number starts with 'M', it was bought new. If it starts with 'F', it’s an official Apple Refurbished unit. If it starts with 'N', it’s a replacement device provided by Apple Support. 'P' means it was personalized with an engraving. This is a pro-tip for buyers: an 'N' model might actually be "newer" than the original purchase date suggests because it was a recent warranty swap.
What Third-Party Lookup Sites Actually Do
Sites like Orchard, EveryMac, or various "iUnlocker" clones exist. They scrape Apple’s GSX (Global Service Exchange) database. They can often provide more granular data than Apple’s consumer-facing site.
For instance, they might show the exact color, storage capacity, and whether "Find My iPad" is currently turned on. This is vital for remote purchases. If you are buying an iPad from a stranger, ask them for a screenshot of the serial number lookup showing "Find My: OFF." If they refuse, walk away.
Be careful, though. Some of these sites are ad-heavy or try to sell you "premium" reports. You generally don't need to pay for a basic serial lookup. The free tools are usually sufficient for 99% of people.

The Privacy Question: Is it Safe to Share Your Serial?
People ask this all the time: "If I give a buyer my serial number, can they hack me?"
Basically, no. They can't remote-access your photos or read your texts just by having the serial. However, they could theoretically report it as stolen to harass you, or use the number to file a fraudulent warranty claim. If you are selling, it’s okay to give the serial to a serious buyer, but don't just post it publicly in an unblurred photo on a public forum.
Actionable Steps for Verification
If you are currently holding an iPad and need to verify it, follow this exact sequence to ensure you aren't missing anything critical.
- Check the physical vs. digital match: Go to Settings > General > About and compare that serial to the one engraved on the back of the case. If they don't match, the internals have been swapped or the housing has been replaced. This is a huge red flag for a "Franken-iPad."
- Verify Activation Lock: Use a secondary device to go to the Apple Check Coverage page. If the device is "locked to owner," the serial number search won't always tell you, so the best way is to try and factory reset the device. If it asks for an Apple ID that isn't yours, it's a brick.
- Cross-reference specs: Use a site like EveryMac to enter the serial. If the site says the serial belongs to a 128GB model but the iPad says it has 256GB, the software has been tampered with or "spoofed." This is common in high-end clones.
- Confirm Warranty status: Especially if you are paying a premium for a "new" device. Apple’s warranty follows the hardware, not the person. If the serial shows 10 months of remaining AppleCare+, that value stays with the iPad when you buy it.
Knowing how to look up iPad by serial number effectively turns you from a vulnerable consumer into an informed one. It's the difference between getting a great deal and getting ripped off by someone selling a bypassed, stolen, or misidentified tablet. Check the back, check the settings, and always run the number through Apple's official portal before you consider the transaction complete.
