Google has added a recovery tool that lets an eligible Android phone reveal its unique equipment identifier from the lock screen. The identifier can help a manufacturer, carrier or law-enforcement agency match a recovered device with ownership records without first unlocking personal content.
The feature is available on Android 12 and newer devices, according to Google, and can be turned off in settings. It uses the phone’s existing IMEI rather than creating a new public identity or granting strangers access to files.
The identifier is the phone’s IMEI
IMEI stands for International Mobile Equipment Identity. Cellular phones receive an individual number that networks and manufacturers use to distinguish the hardware. In its 2026 Android security announcement, Google described lock-screen access to that number as a way for authorized organizations to verify ownership and return a lost phone.
An IMEI is not a password, encryption key or live location. Knowing it should not unlock the device or expose photographs, messages and account data. Its recovery value comes from comparing the number with purchase records, carrier data, a lost-device report or another record tied to the owner.
Recovery still requires a trusted intermediary
The lock-screen option does not let any passerby query a universal owner directory. Google names law enforcement, the device manufacturer and the mobile carrier as parties that may use the identifier to help verify a claim. Those organizations can compare it with records already held through legitimate business or investigative processes.
That distinction keeps the number from becoming proof on its own. A person who reads an IMEI from the lock screen has identified a piece of hardware, not established a right to possess it. A responsible recovery process should require corroborating account, purchase or report information before handing over the phone.
Android’s lost-phone tools provide the active controls
The identifier complements rather than replaces Google’s remote recovery service. The company’s Find Hub instructions describe how a signed-in owner can locate, secure or erase a supported device. Location and remote actions depend on factors such as power, connectivity, account access and the phone’s settings.
Marking a device as lost can place contact information on the screen so an honest finder has a direct return route. A remote erase is more final: it protects stored information but can end the ability to locate the handset through the account. Owners therefore need to weigh data exposure, evidence of theft and the chance of recovery before choosing that step. Carrier suspension can stop cellular service without necessarily wiping local data.
Android 17 also strengthens the “Mark as lost” process by requiring biometric authentication for sensitive changes, Google said. That protection is meant to keep someone holding a stolen unlocked phone from weakening recovery controls. Phones on earlier supported Android versions may expose the recovery identifier without receiving every Android 17 feature at the same time.
A visible serial number has privacy tradeoffs
Making a durable identifier accessible while a device is locked creates a deliberate exchange: recovery agents gain a way to identify hardware, while someone with physical access may also read the number. Google says the option can be disabled, giving owners who regard exposure as the greater risk a way to close it.
The IMEI should not be posted publicly or shared casually. Criminals have used device identifiers in fraudulent reports and social-engineering attempts, even though the number alone normally cannot unlock a phone. Screenshots, online sales listings and repair communications should conceal it unless a trusted carrier, manufacturer or agency needs it for a defined purpose.
Preparation determines whether recovery works
A recovery identifier is most useful when ownership records are already organized. Saving a receipt, carrier account record and device serial information outside the phone gives an owner evidence to present after a loss. A strong screen lock and current account-recovery information help prevent the loss from turning into a broader identity compromise.
The Federal Communications Commission’s mobile-device guidance recommends recording identifying information, contacting the wireless provider after theft and reporting a stolen device to police. A carrier may be able to suspend service or block a reported device from its network, actions that are separate from Android’s location and lock tools.
The feature helps identify a phone, not guarantee its return
A powered-off handset, damaged device or phone moved across jurisdictions may remain difficult to recover. Records can also be incomplete, and not every agency or carrier will use the same return procedure. The new lock-screen route removes one practical obstacle by making the hardware number available without defeating the owner’s screen lock.
The safest response to a missing phone remains layered: use remote tools, notify the carrier, preserve account security and file a report when theft is suspected. The IMEI option gives trusted recovery organizations a common reference point while leaving encrypted personal data behind the lock screen.
