You just found a "steal" on Facebook Marketplace. The shrink-wrap looks crisp. The Apple logo is there. But deep down, you've got that nagging feeling that something is off. Fake AirPods are basically a global industry now, and they're getting terrifyingly good at mimicking the real thing. To be safe, you have to verify AirPods serial number details before you even think about pairing them to your iPhone. It’s the only way to stay ahead of the scammers.
Look, I’ve seen fakes that actually trigger the official "pairing" animation on an iPhone. They’ve even figured out how to fake the "Transparency Mode" UI, even if the actual hardware doesn't do a thing. It's wild. But the serial number remains the strongest link in the chain, provided you know where to look and what the results actually mean.
The First Step: Finding the Number Without the Box
Most people reach for the box first. Don't do that. Scammers often put 1:1 replica buds inside a genuine Apple box they found in the trash or bought on eBay. It's a classic bait-and-switch. You need to find the number on the hardware itself.
On AirPods or AirPods Pro, look at the underside of the lid. There’s a tiny string of alphanumeric characters printed right in the chassis. It's small. You might need your phone's flashlight and a bit of squinting to see it clearly. For AirPods Max, you actually have to magnetically remove the left ear cushion. The serial number is printed on the top of the ear cup assembly.
If you’ve already paired them—maybe you’re checking a pair you bought months ago—just go to Settings > Bluetooth. Tap the little "i" icon next to your AirPods. Scroll down. The serial number is listed right there in the software.
Why the Software Check Isn't Enough
Here is the kicker: high-end "Supercopies" can actually spoof the serial number in the iOS Settings menu. They hard-code a real, stolen serial number into the firmware. This is why you must compare the number in the Settings app against the number printed on the physical charging case. If they don't match? You’ve got a fake. Case closed. Literally.
How to Verify AirPods Serial Number Using Apple’s System
Once you have that code, you head over to the official Apple Check Coverage page. This is the moment of truth.
When you plug that number in, a few things can happen. If the site says "Invalid Serial Number," you’re done. It's a fake. Don't let the seller tell you it's because they're "international models" or "from a special wholesale batch." That’s nonsense. Apple’s database is global.
However, a "Valid" result isn't a 100% guarantee of authenticity anymore. Scammers are clever. They find one legitimate serial number from a real pair of AirPods and print that same number on ten thousand fake units. This is why you check the Purchase Date.
If the Apple site says the "Purchase Date" is not validated, that’s actually often a good sign for a brand-new pair. It means they haven't been registered yet. But if you're buying "brand new" buds and the site says the warranty expired in 2023? You're looking at a clone using a stolen serial number.
The "Duplicate" Warning
Sometimes, Apple’s system might flag a number that has been checked too many times. While rare for average users, if you see any messaging suggesting the device has been replaced or has a weird service history you weren't told about, walk away.
Physical Red Flags That the Serial Number Won't Catch
Let's say the serial number checks out. The site says they're real. You still need to use your eyes. Apple’s printing is precise. On the bottom of the AirPods stems or inside the case, the text should be a soft, light grey. Fakes often use a dark, bold black ink that looks "stamped" on.
- The Hinge Test: The hinge on a real AirPods Pro case is made of high-quality metal. It should feel snappy. If it feels like cheap plastic or has a lot of "wiggle" side-to-side, it's a dud.
- The Light Bleed: Take your phone's flashlight and hold it against the back of the charging case lid (while open). Genuine Apple plastic is dense. You shouldn't see much light leaking through the plastic itself. Many clones use thinner, cheaper plastic that glows like a lantern.
- The Grilles: Look at the black grilles on the buds. On real AirPods, these are perfectly flush with the body. On fakes, they often look slightly recessed or, worse, they’re just stickers or paint.
The Firmware Trap
This is a deep-cut tip. Real AirPods receive firmware updates automatically from Apple. Go back to your Bluetooth settings and look at the Version number. Look up the current firmware version for your specific model on Apple's support site.
Clones usually run on "fixed" firmware. They can't be updated. If your AirPods are stuck on a version from two years ago and won't update no matter what you do, you're likely holding a very convincing counterfeit.
It’s also worth checking the "Find My" integration. Genuine AirPods (especially the Pro 2 and Max) have deep integration with the Find My network, including "Precision Finding" using the U1 or U2 chip. Most fakes can show up on a map, but they won't give you that "Left/Right/5 feet away" directional arrow because they lack the expensive Ultra Wideband hardware.
Why Does This Even Matter?
You might think, "Hey, if they sound okay and look real, why do I care?"
Battery safety is the big one. Genuine Apple products use high-quality lithium-ion cells with sophisticated charging controllers. Fakes? They use the cheapest batteries available. There are documented cases of counterfeit headphones overheating or even exploding while charging.
Then there's the sound. Apple spent billions on the H1 and H2 chips to handle Computational Audio. Clones use off-the-shelf Bluetooth chips that might sound "fine" at first but lack the dynamic range and Active Noise Cancellation (ANC) power of the real deal. You’re essentially paying 50% of the price for 10% of the tech.
Actionable Steps to Protect Your Wallet
If you’re currently in the middle of a deal or planning to buy soon, follow this checklist. Don't skip a step because you're in a hurry.

- Ask for the serial number before you meet. A legitimate seller will give it to you. If they get defensive, that's your red flag.
- Run the number through Apple's Check Coverage site. Look for inconsistencies in the warranty date.
- Cross-reference the physical number. Ensure the number on the box, the number inside the case lid, and the number in the iOS Settings app are identical.
- Check for "Spatial Audio" functionality. Connect them to your iPhone, open the Control Center, long-press the volume bar, and toggle Spatial Audio. Real AirPods will noticeably shift the soundstage. Most fakes will do nothing or just change the volume.
- Weight them. If you have a kitchen scale, use it. Apple's specs are public. For example, a MagSafe Charging Case for AirPods Pro (2nd Gen) should weigh exactly 50.8 grams. Clones are almost always lighter because they use fewer internal magnets and lower-density plastics.
Buying from authorized retailers like Best Buy, Target, or the Apple Store itself is the only way to be 100% certain. But if you’re hunting for a deal on the secondary market, being obsessive about the serial number is your only real defense. It takes two minutes to check, and it could save you hundreds of dollars and a massive headache.
Verify the details, trust your gut, and if the price seems too good to be true, it almost certainly is.
