IMEI Check in Europe: Blacklists and Used Phone Guide

An IMEI is the identity a mobile phone presents to cellular networks. Checking it is essential when buying a used phone in Europe, but there is no single official EU website that can certify a handset as clean across every country and carrier. A format check, an operator blacklist check, carrier compatibility and Apple or Android account locks are separate checks.

Start with the free IMEI validator on Tuble.net. It checks the 15-digit format and Luhn check digit, then separates the TAC, serial portion and check digit. It does not query police, carrier or GSMA block lists, so continue with the country-specific checks below.

What an IMEI is — and what it is not

IMEI stands for International Mobile Equipment Identity. It identifies cellular equipment, not the person using it.

A current IMEI contains 15 decimal digits:

• TAC, digits 1–8 — identifies an approved device model or model family;
• serial portion, digits 9–14 — assigned by the manufacturer to the individual unit;
• check digit, digit 15 — calculated using the Luhn algorithm to catch common transcription errors.

A valid check digit proves only that the number is mathematically well formed. It does not prove that the phone is genuine, paid off, unlocked, compatible, legally owned or absent from every lost-and-stolen database.

IMEI is different from:

• the phone number and SIM card;
• ICCID, which identifies a SIM or eSIM profile;
• EID, which identifies an eSIM chip;
• the manufacturer serial number;
• Apple Activation Lock, Google Factory Reset Protection or corporate MDM status.

How to identify a phone model from its TAC

Take the first eight digits of the IMEI. This is the Type Allocation Code (TAC). A manufacturer receives TACs for particular models or hardware variants, so a TAC database can suggest the brand and model.

Illustrative entries for popular phones include:

• 86217103 — Apple iPhone 16 Pro;
• 86425604 — Apple iPhone 16 Pro Max;
• 35256811 — Samsung Galaxy S24 Ultra;
• 35961215 — Samsung Galaxy S25 Ultra;
• 35154913 — Samsung Galaxy A54 5G;
• 86734502 — Samsung Galaxy A15.

If an IMEI begins with 86217103, those first eight digits identify one iPhone 16 Pro allocation. The next six digits are the unit’s serial portion and the last digit is the Luhn check digit.

These are examples, not a complete catalogue. One model can receive several TACs for different regions, radio hardware, revisions or production volumes. An unfamiliar TAC does not automatically mean counterfeit. A familiar match does not prove authenticity either, because a genuine identifier can be cloned. Compare the TAC result with Settings, documents and the physical phone.

Dual SIM, IMEI1, IMEI2 and eSIM

Many current phones display IMEI1 and IMEI2. A dual-SIM dual-standby phone normally needs a unique IMEI for each cellular connection that can remain active or listening at the same time. A device using passive switching may expose only one.

Check every IMEI shown by the phone. One line can be clear while the other is blocked, copied from another device or omitted from the listing.

An eSIM still uses an IMEI for the cellular equipment. Its EID is a separate identifier and must not be entered in an IMEI checker.

How to find every IMEI

1. Dial ***#06#**.
2. On iPhone, open Settings → General → About.
3. On Android, open Settings → About phone; wording varies by manufacturer.
4. Compare the numbers with the original box, invoice and any markings on the SIM tray or body.
5. If the device is already linked to a manufacturer account, compare the identifier shown there.

The number on screen, in Settings and on the sales documents should agree. A mismatch is a strong reason to stop the purchase.

What the Tuble IMEI validator checks

The Tuble.net IMEI tool runs locally in your browser. It:

• accepts a 15-digit IMEI;
• verifies the Luhn check digit;
• identifies the TAC, serial portion and check digit;
• catches typing errors and clearly malformed identifiers.

It does not connect to GSMA Device Check, national equipment registers, police, insurers, finance companies or mobile operators. A green validation result is the first technical screen, not a stolen-phone report.

Is there an official EU IMEI blacklist checker?

No. The European Union does not operate a public, EU-wide stolen-phone lookup.

Mobile operators maintain Equipment Identity Registers and may exchange block-list data nationally or through the GSMA Device Registry. Participation and international sharing are uneven. A phone blocked in one country may not be blocked immediately — or at all — in another.

GSMA Device Check queries an industry block list. It is not an EU government service, public access can be limited, and a result covers only data supplied by participating organisations. A device not currently listed can still be stolen, financed, account-locked or rejected by a particular network.

Avoid websites advertising an “official EU blacklist.” Confirm who runs the service, which database it queries and which countries contribute before paying.

How IMEI blocking differs across Europe

France

France has a shared operator process, but individuals cannot directly search its stolen-device database. In case of theft:

1. suspend the SIM with the operator;
2. file a police or gendarmerie complaint containing the IMEI;
3. the authorities transmit the official declaration;
4. under Article L34-3, the operator blocks the identified handset within four working days after receiving it.

Loss and theft may follow different procedures. Check current guidance from ARCEP and Service-Public.

Spain

Spanish operators describe national IMEI blocking after loss or theft. Operator guidance says a blocked device cannot be used with another Spanish SIM, but reversal after recovery can take time because carriers share the status. There is no verified public government lookup for a used-phone buyer.

Germany

Consumers should block the SIM and report the IMEI to police. Current IMEI-barring practice varies by operator, and no nationwide public checker was verified. Ask the carrier that will be used rather than assuming a foreign report applies.

United Kingdom

The UK is no longer in the EU but is relevant to cross-border European purchases. CheckMEND offers a paid device-history report covering reported loss, theft, insurance, blocking and possible cloning. It is a commercial service, not a government certificate.

UK law specifically prohibits unauthorised reprogramming of unique mobile-device identifiers. That rule should not be generalised to every European jurisdiction without checking local law.

Other European countries

Belgium, Italy, Ireland, the Netherlands, the Nordics and Central and Eastern Europe use combinations of police reports, carrier systems and optional GSMA sharing. No universal public checker was verified. Contact the operator in the country where the phone will actually be used.

A clean IMEI does not guarantee network compatibility

A correct or unlisted IMEI can still fail on a European network because of:

• missing LTE or 5G bands;
• unsupported VoLTE or Wi-Fi Calling;
• carrier-specific certification;
• a SIM lock from the original operator;
• regional eSIM restrictions;
• an overseas model with different radio hardware.

Test the phone using a SIM from the intended country and carrier before paying. This is especially important for grey imports and models originally sold in North America or Asia.

Lost, stolen, financed and account-locked are different states

An IMEI block normally prevents cellular service on participating networks. It does not:

• disable Wi-Fi;
• remove data or sign out apps;
• locate the phone;
• remove Apple Activation Lock;
• remove Android FRP;
• prove that the seller owns the device;
• settle unpaid finance or an insurance claim.

A seller can also report a device stolen after selling it. Obtain the original invoice and a written receipt containing every IMEI and the seller’s identity.

IMEI cloning and counterfeit phones

A cloned IMEI is copied from another handset. Because the copied number may be real, it can pass the Luhn check and return the expected model.

Warning signs include:

• *#06#, Settings, box and listing show different numbers;
• IMEI1 and IMEI2 map to unrelated models;
• the seller provides screenshots but refuses a live check;
• the TAC indicates a different model or region;
• the phone loses network access after initially working;
• labels look replaced or altered.

No online result can identify which physical handset is genuine when two devices share the same identifier. Treat any mismatch as a failed check.

Used-phone IMEI checklist for Europe

1. Meet in person in a safe public place.
2. Dial *#06# and record every IMEI.
3. Match the numbers with Settings, box and invoice.
4. Validate each number using Tuble.net.
5. Use the checker or operator process available in the country of use.
6. For a UK-origin phone, consider a CheckMEND report.
7. Insert a local SIM and test calls, SMS, mobile data and VoLTE.
8. Confirm that the phone is carrier-unlocked.
9. Ask for the original invoice and a signed receipt listing all identifiers.
10. Have the seller remove Apple, Google and Samsung accounts.
11. Factory-reset and begin activation before payment.
12. Check battery health, display, cameras, microphones, speakers, biometrics and repair history.

iPhone and Android account locks

For an iPhone, the seller must turn off Find My, sign out of the Apple Account and erase the phone. Begin setup with an internet connection. Do not buy if it displays Locked to Owner or asks for the previous owner’s credentials.

For Android, the seller should remove Google and manufacturer accounts, reset through Settings and let you complete initial setup. A reset performed incorrectly can trigger Factory Reset Protection.

Corporate devices may remain enrolled in Apple Business Manager, Android Enterprise, Samsung Knox or another MDM platform. Reject a phone that displays remote-management enrolment unless the organisation removes it.

What to do if your phone is stolen

1. Suspend the SIM with your operator.
2. Use Apple Find My or Google Find Hub to secure the device.
3. Report the theft to local police and provide every IMEI, the invoice and box.
4. Ask the operator about IMEI blocking in that country.
5. Keep the device in your manufacturer account while recovery remains possible.

Record your IMEIs before a loss. Police and operators may be unable to place an accurate block without them.

An IMEI check in Europe is a process, not one green badge: validate the number, use the relevant national or operator system, test the intended network, verify ownership and remove all account locks before money changes hands.
