How to Check the IMEI Number on a Samsung Device

Every Samsung phone — and virtually every mobile device — carries a unique 15-digit identifier called an IMEI number (International Mobile Equipment Identity). Knowing how to find and verify it is one of the most practical skills a Samsung owner can have, whether you're buying a used device, troubleshooting a network issue, or reporting a stolen phone.

What Is an IMEI Number and Why Does It Matter?

The IMEI is a globally unique serial number assigned to every cellular-capable device. Unlike a SIM card, it's tied to the hardware itself, not the account or network. Mobile carriers, law enforcement agencies, and third-party verification services all use it to:

• Identify a specific device across any network
• Blacklist stolen phones so they can't be activated
• Verify purchase history and warranty status
• Check network lock status (carrier-locked vs. unlocked)
• Confirm the device model and country of origin

When you're buying a second-hand Samsung, the IMEI is the single most important number to check before handing over money.

Method 1: The Universal Dial Code 📱

The fastest method works on virtually every Samsung device running any version of Android:

1. Open the Phone app (the standard dialer)
2. Type *#06#
3. The IMEI will appear on screen immediately — no need to press call

On dual-SIM Samsung models (common across the Galaxy A and S series), you'll see two IMEI numbers — one for each SIM slot. Both are valid identifiers for the same physical device.

Method 2: Through Samsung Settings

If the dial code doesn't work or you prefer navigating through menus:

1. Go to Settings
2. Scroll down to About Phone
3. Tap Status Information (on newer One UI versions) or just Status
4. Select IMEI Information

The exact path varies slightly depending on your One UI version. Older Samsung devices running One UI 3 or earlier may display the IMEI directly under About Phone > Status without the extra sub-menu.

Method 3: Physical Locations on the Device

If the phone won't power on, you still have options:

The SIM tray method is the most reliable for current Galaxy devices — Samsung prints a small label on the tray itself with the IMEI. The retail box typically shows it on the barcode sticker near the bottom.

Method 4: Samsung Account and Find My Mobile

If you've registered your device with a Samsung account:

1. Visit findmymobile.samsung.com
2. Sign in with your Samsung credentials
3. Select the device from your registered list
4. The IMEI is listed under device details

This is particularly useful if you no longer have physical access to the device — for example, if it's been lost or stolen and you need to file a report.

How to Actually Verify an IMEI (Not Just Find It)

Finding the IMEI is step one. Verifying it — checking what that number reveals about the device's history — is a separate process. Several services can query IMEI databases and return information such as:

• Blacklist status (reported stolen or lost)
• Carrier lock status (network-locked or unlocked)
• Original country/region of sale
• Warranty and activation date
• Model number and specifications

Free options include the GSMA Device Check portal and carrier-specific tools (major carriers often provide IMEI checkers on their websites). Paid third-party services typically offer more detailed reports including full carrier history and financed-device status (sometimes called "financial blacklist" checks).

Key Variables That Affect What You'll Find 🔍

Not every IMEI check returns the same level of detail. What you get depends on several factors:

Which database is queried — Blacklist status is only as accurate as the database it pulls from. Regional databases don't always share information across borders, so a phone blacklisted in one country may not show as blacklisted in another.

Dual-SIM devices — Samsung phones with two SIM slots have two IMEIs. Some checking services only query one. If you're verifying a dual-SIM device, check both numbers.

Device region — A Samsung sold in Southeast Asia, Europe, or Latin America may have different model codes and band configurations. The IMEI can confirm the original region, which matters for network compatibility.

Report age — Stolen device reports aren't always filed immediately. A clean IMEI check today doesn't guarantee the device won't be flagged tomorrow if it was recently stolen and the report is pending.

Carrier-specific tools — A carrier's own IMEI checker is usually only reliable for devices originally sold through that carrier's network. Cross-carrier or international devices may return incomplete data.

What a Clean Check Does — and Doesn't — Tell You

A clean IMEI result means the device hasn't been flagged in the queried database at the time of the check. It does not confirm:

• The device is fully functional
• The device hasn't been reported elsewhere
• The original purchase was legitimate in all markets

For a used Samsung purchase, combining an IMEI check with a physical inspection and a power-on test gives a much more complete picture than any single method alone.

Dual-SIM IMEI: Which One to Use?

If your Samsung has two IMEI numbers, the distinction matters in specific situations:

• Reporting theft: Provide both IMEIs to the carrier and police
• Warranty checks: Either IMEI should return the same device record
• Carrier unlock requests: Use the IMEI associated with the SIM slot currently in use
• Third-party verification: Check both, since reports may be attached to either

The primary IMEI (IMEI 1) is typically the one associated with SIM slot 1 and is the number most commonly referenced in carrier records.

How much any of this matters in practice depends on why you're running the check — verifying a used purchase, troubleshooting a network issue, and filing a theft report are all meaningfully different situations with different requirements for what information you actually need.
