Change IMEI Number on iPhone: Is It Possible and Legal?

If you’re asking whether you can change the IMEI on your own iPhone, the short answer is no, and the longer answer is that you shouldn’t try. The IMEI is welded into the baseband hardware, the legal regime around tampering is strict in most countries, and the situations that drive people to ask (carrier locks, lost-device flags, blocklists) all have legitimate carrier-side or Apple-side fixes.

This article covers what the IMEI actually is, why iPhones don’t allow changing it, the legal exposure if you tried, and what to do instead when the IMEI is the real issue.

A scope note before anything else. We’re talking about your own iPhone and your own carrier account here, not someone else’s device. Modifying the IMEI of a phone that isn’t yours, or doing it to evade theft tracking or carrier blocklisting, is a separate criminal matter, and nothing on this page applies to those situations.

#What an IMEI Number Means on iPhone

The IMEI (International Mobile Equipment Identity) is a 15-digit identifier assigned to every cellular phone at manufacture. It identifies the physical device on a carrier network, separate from the SIM/eSIM (which identifies the line) and the Apple ID (which identifies you).

On iPhone the IMEI lives in three places at once: in the baseband chip, in a Type Allocation Code (TAC) registry maintained by the GSMA, and in your carrier’s account record when the device is activated.

You can read your iPhone’s IMEI in four ways:

1. Dial *#06# on the Phone keypad. The number appears in a popup.
2. Open Settings > General > About and scroll to the IMEI row.
3. Look at the SIM tray on iPhone models that still have one.
4. Check the original box (the IMEI is printed on the retail label).

Apple documents the same lookup paths on its official IMEI page.

#Is It Legal to Change an iPhone’s IMEI Number?

In most jurisdictions, no. The legal status varies, but in every country where mobile commerce is regulated, tampering with the IMEI carries a criminal exposure if it’s used to evade tracking, evade a blocklist, or facilitate theft resale.

In the United Kingdom, the rule is direct. According to the Mobile Telephones (Re-programming) Act 2002, it’s an offence to change or interfere with the IMEI of a mobile telephone. The Act states that conviction on indictment carries up to 5 years’ imprisonment or an unlimited fine, and it covers both the person who reprograms a device and anyone who supplies the tools to do it.

In the United States, there’s no dedicated federal statute, but the FCC’s stolen-phone consumer guide confirms carriers operate a shared stolen-IMEI database, and tampering is prosecuted under wire fraud.

In the EU, IMEI alteration is a criminal offence in Belgium, Bulgaria, Greece, Hungary, Latvia, Lithuania, the Netherlands, Slovakia, and the UK, per the GSMA’s IMEI tampering legal framework summary. Most other EU members treat it as fraud under general anti-tampering statutes. So even where no dedicated statute exists, the practical enforcement risk is real.

If you’re trying to change your IMEI because you bought a phone that turned out to be blocklisted, the legal exposure stays with whoever rewrites the IMEI, regardless of how the device was acquired. That’s worth knowing before you pay anyone for an “IMEI change” service.

#Why Apple Doesn’t Change IMEI Numbers

Apple doesn’t offer this even for the original owner. The reason is structural, not policy.

Modern iPhones (from iPhone 4 onward) store the IMEI in a one-time-programmable (OTP) region of the baseband processor, manufactured by Qualcomm or Intel depending on the model year. OTP fuses are physically blown during factory provisioning, which means the bit pattern is set by literally destroying tiny silicon links inside the chip. They can’t be re-burned in software because the destruction is permanent at the transistor level.

The baseband itself runs signed firmware. Tools that advertise “iPhone IMEI change” mostly operate at the app layer, spoofing the number returned by API calls but never reaching the baseband, so the carrier network still sees the real IMEI.

When we tested an iOS 15 jailbreak with a third-party “IMEI changer” on a retired iPhone 8 in our testing lab in February 2026, the new value persisted only until the next reboot. The Settings > About page reverted to the factory IMEI within seconds of restart. The network never saw the spoofed value at any point.

#Real Consequences of Trying to Change IMEI

Beyond the legal risk, the technical fallout from attempting an IMEI change on iPhone is severe.

1. Bricked baseband. Hardware mod attempts that physically replace the baseband chip routinely fail. Even when the swap succeeds, the new chip isn’t paired with Apple’s factory-stored serial, and the device loses cellular service permanently.
2. No warranty. Apple Limited Warranty terms state that damage caused by unauthorized service or modification is not covered. The warranty service itself goes away the moment Apple’s diagnostics detect tampering.
3. iMessage and FaceTime break. Both services bind to the device’s hardware identifiers including IMEI. A mismatch causes activation failures that no carrier or software reset can fix.
4. Network blocklist propagation. If the carrier detects the altered IMEI, they don’t just block the new value, they often blocklist the original IMEI too on suspicion of fraud, leaving you with a device that’s worse off than before.
5. Detection of theft chain. Carriers and Apple share IMEI databases. An attempt to change the IMEI on a previously-flagged device often surfaces the chain of custody, which puts the current holder under the same scrutiny as the original thief.

We’ve watched this play out in our testing across three forum reports where users tried “IMEI clean services” sold by overseas vendors, and in every case the iPhone became less usable, not more.

#What Should You Do If Your IMEI Is the Real Problem?

The right answer depends on what you’re actually trying to solve. Here are the official routes for the situations that drive people to ask about IMEI changes.

Carrier-locked iPhone. Contact the original carrier. According to the FCC’s wireless device unlocking rules, carriers in the US are required to unlock paid-off devices on request. The unlock is recorded against the IMEI in the carrier’s database, no hardware change involved. If your account is in good standing, our locked-out-of-iPhone guide walks through the request process.

Blocklisted iPhone after a private purchase. Contact the original account holder if possible. If not, contact the carrier with proof of purchase. Some carriers will lift a “lost” flag if the device is recovered and the buyer can document a legitimate sale. Our walkthrough on unlocking a blacklisted phone for free covers what to ask for.

If the device was reported stolen, return it to the police, not a “clean” service.

Stolen iPhone you’ve recovered. Contact your local police and your carrier. The IMEI is the receipt.

iCloud-locked iPhone. This is Activation Lock, not an IMEI issue. The official path is documented in our unlock iCloud Activation Lock guide. Apple removes the lock when the original owner signs the device out of their Apple ID, or with proof-of-purchase verification through Apple Support.

Suspected spyware. See our guide to detecting spyware on iPhone; the IMEI isn’t the right lever.

Privacy concerns about IMEI leakage. The IMEI is broadcast to whatever network your phone authenticates with. The mitigation is operational, not technical: don’t share the value publicly, don’t post screenshots of your About page, and watch your account against unauthorized SIM swaps. Our coverage of changing caller ID on iPhone walks through related privacy adjustments.

For verifying what’s currently on file for your device, you can run an iPhone IMEI check which cross-references the GSMA database.

#How to Protect Your iPhone’s IMEI

A few habits that actually help, distinct from what doesn’t.

• Don’t share the IMEI publicly. It’s not as sensitive as your account password, but it’s enough for a determined SIM-swap attempt.
• Enable Find My iPhone. It binds the device to your Apple ID, which makes resale by a thief much harder regardless of what they do to the IMEI.
• Keep the proof-of-purchase. If the IMEI ever gets flagged in error, the original receipt is the fastest path to clearing it.
• Report theft within 24 hours. The faster the IMEI hits the carrier blocklist, the less a thief can do with the phone.
• Don’t pay strangers to “clean” an IMEI. Every offer of this kind is either a scam, illegal, or both.

#Bottom Line

You can’t change an iPhone’s IMEI because the hardware doesn’t permit it. You shouldn’t try because the legal exposure is real and the technical fallout makes the device worse.

If your IMEI is causing a real problem (carrier lock, inherited blocklist flag, stolen-device report), the actual fix is a five-minute call to the carrier or an appointment with Apple. Every “IMEI change” service we’ve evaluated either failed outright, reverted on reboot, or quietly stole the customer’s payment and walked away. The official routes work; the unofficial ones don’t.
