Samsung IMEI Generator: TAC Codes, Android Dev & Enterprise Testing

Samsung is the world's largest Android device manufacturer, with hundreds of active device models ranging from budget A-series phones to flagship Galaxy S and Z series. If you build Android applications, manage enterprise mobile fleets, or test telecom infrastructure, you will at some point need realistic Samsung IMEI numbers for your test environment. A proper Samsung IMEI generator gives you structurally valid numbers tied to real Samsung TAC codes — essential for any test that goes beyond basic string validation.

This guide covers Samsung's TAC code structure, the specific testing scenarios where generated IMEIs are necessary, and how to integrate them correctly into Android development and enterprise workflows.

How Samsung IMEI Numbers Are Structured

Like all mobile devices, Samsung phones use the 15-digit IMEI format defined by the GSMA. The structure breaks down as follows:

IMEI: 3 5 3 4 9 0 1 0 | 1 2 3 4 5 6 | 7
      └───────────────┘ └───────────┘ └─
         TAC (8 digits)   Serial (6)   Check

• TAC (Type Allocation Code): The first 8 digits. Identifies the manufacturer (Samsung) and specific device model/hardware revision.
• Serial Number: Digits 9–14. Manufacturer-assigned production serial within the TAC block.
• Check Digit: Digit 15, calculated via the Luhn algorithm.

Samsung has an exceptionally large number of registered TAC codes because each device model has multiple variants: different regions (European, US, Korean, Chinese markets), different carrier versions, different RAM/storage configurations, and different hardware revisions throughout a product's lifecycle.

Samsung's Reporting Body Identifier

The first two digits of a Samsung IMEI commonly include 35 (UK BABT), 86 (China), and 01 — depending on the device's origin market. Most international Samsung devices sold in Europe start with 35. US carrier-specific variants often have different prefixes, which is why a Samsung Galaxy S24 sold by T-Mobile may have a different TAC than the unlocked international version of the same phone.

Samsung TAC Codes by Device Family

Here is a reference table of representative Samsung TAC codes by product line:

Note: Samsung model numbers encode region (B = Europe, U = US, N = Korea), carrier, and hardware variant. The same physical device sold in different markets has different TAC codes. The table above is illustrative.

Why Android Developers Need a Samsung IMEI Generator

1. Android Enterprise (AE) and Knox Testing

Samsung Knox is the most widely deployed enterprise security platform on Android. Corporations use Knox to enforce device policies, containerize work apps, and remotely wipe lost devices. The Knox platform identifies devices by IMEI during enrollment via Android Enterprise (formerly Android for Work).

When you are developing a Knox integration — whether a custom MDM plugin, a Knox Configure profile, or a Knox Mobile Enrollment flow — you need to simulate device registrations. This requires valid Samsung IMEIs that correspond to supported device families. A Galaxy S23 IMEI and a Galaxy A14 IMEI will trigger different policy sets in many enterprise configurations.

2. Android App Development and Emulator Limitations

Android emulators have a standard behavior: TelephonyManager.getDeviceId() returns a static, fake IMEI like 000000000000000. This is fine for basic testing, but it breaks test cases that validate IMEI format, detect device generation, or implement per-device licensing.

If your app's backend needs to accept a real IMEI and return device-specific behavior (different feature sets for flagship vs. budget devices, for example), you need test data that uses authentic Samsung TACs — not zeroes.

3. Testing Samsung-Specific APIs

Samsung exposes device-specific APIs through the Knox SDK and the Samsung Developer Program. These APIs often behave differently based on device model. Testing your implementation against a Galaxy S24 Ultra versus a Galaxy A series device may produce different results. When you cannot test on physical hardware for every model variant, you need IMEI-based mock data to simulate the correct device context.

4. Telecom Backend and MVNO Development

Mobile Virtual Network Operators (MVNOs) and telecom developers building SIM provisioning systems, Number Portability databases, or billing platforms need to test with realistic subscriber records. Each subscriber record pairs an MSISDN with an IMEI. Generating valid Samsung IMEIs lets you create synthetic subscriber records that behave like real Samsung customers without using any actual customer data.

5. Device Finance and Insurance Platform Testing

Platforms that offer installment financing, insurance, or extended warranty for Samsung devices typically perform IMEI-based device lookup at the point of sale. During development and QA, you need to test what happens when a Galaxy S24 Ultra is submitted (high-value, eligible for premium plan) versus a Galaxy A14 (budget tier, different plan). Generated Samsung IMEIs tied to specific TAC codes let you simulate the full range of device scenarios.

Samsung's Multi-SIM Complexity

Samsung is one of the leading manufacturers of dual-SIM and multi-SIM devices, particularly for emerging markets. Understanding how this affects IMEI assignment is critical for accurate testing.

Dual-SIM Samsung Devices

A Samsung dual-SIM phone has two IMEI numbers: IMEI1 for the primary SIM slot and IMEI2 for the secondary slot. Both share the same TAC but have different serial numbers. On the device, you can see both by dialing *#06#.

For testing telecom systems that handle dual-SIM devices:

• Both IMEIs must be structurally valid
• Both must share the same TAC (same device model)
• The serial numbers must be different

Samsung Tablets with Cellular

Samsung Galaxy Tab devices with LTE/5G connectivity also have IMEIs. Their TAC codes fall under a separate Samsung tablet TAC block. If your MDM or telecom system handles both phones and tablets, make sure your test data includes tablet IMEIs, not just phone IMEIs.

Generating Valid Samsung IMEIs

Using RandomIMEI.com, you can generate structurally valid Samsung IMEIs in bulk. The process:

1. Navigate to the generator
2. Select Samsung as the manufacturer filter
3. Optionally specify device family (flagship S-series, A-series, Z-series)
4. Choose quantity (1 to thousands for batch testing)
5. Export as plain text, CSV, or JSON

Each generated IMEI:

• Starts with a validated Samsung TAC prefix
• Contains a pseudo-random serial number within the TAC block
• Has a Luhn-calculated check digit
• Is not registered in the GSMA EIR — it cannot be used on a live network

This last point is crucial. The generated number is a valid data structure, not a real device identity. It will pass format validation in any system, but it will fail any lookup against real carrier databases or device registries.

Practical Testing Scenarios with Samsung IMEIs

Scenario 1: Knox Enrollment Testing

You are building a zero-touch enrollment flow for a Samsung Knox deployment. You need to pre-populate the Knox Mobile Enrollment portal with 200 device IMEIs before the physical devices arrive at employees' desks.

# Generate 200 Samsung Galaxy S24 IMEIs (TAC: 35349010)
# Output to CSV for Knox portal import
curl "https://randomimei.com/api/generate?tac=35349010&count=200&format=csv" \
  -o test_devices.csv

Scenario 2: Android Unit Test with Realistic IMEI

// Kotlin unit test - mock TelephonyManager with Samsung IMEI
@Test
fun testDeviceRegistration_withSamsungImei() {
    val mockTelephonyManager = mockk<TelephonyManager>()
    // Galaxy S24 Ultra IMEI (generated, not real)
    val testImei = "353490101234562"
    every { mockTelephonyManager.imei } returns testImei

    val result = deviceRegistrationService.register(testImei)

    assertEquals(DeviceTier.FLAGSHIP, result.tier)
    assertTrue(result.isKnoxCompatible)
}

Scenario 3: Database Load Testing

For load testing a device management database, you need 50,000 unique Samsung IMEIs with realistic distribution across device families:

This distribution reflects real-world enterprise fleet composition and produces more realistic query performance results than using a single TAC code for all 50,000 records.

Validating Samsung IMEIs in Your Code

Before loading generated IMEIs into a production test environment, always validate them programmatically:

// Node.js / JavaScript Luhn validation
function validateIMEI(imei) {
  if (!/^\d{15}$/.test(imei)) return false;

  let sum = 0;
  for (let i = 0; i < 15; i++) {
    let digit = parseInt(imei[i]);
    if (i % 2 === 1) {  // Double every second digit from left (0-indexed)
      digit *= 2;
      if (digit > 9) digit -= 9;
    }
    sum += digit;
  }
  return sum % 10 === 0;
}

// Test with Samsung Galaxy S24 Ultra IMEI
console.log(validateIMEI("353490101234562")); // true
console.log(validateIMEI("353490101234563")); // false (wrong check digit)

Responsible Use of Generated Samsung IMEIs

Generated Samsung IMEIs are legitimate tools for software development. Here is the clear line:

Permitted uses:

• ✅ Android app development and unit testing
• ✅ Knox and Android Enterprise MDM testing
• ✅ Database seeding and performance testing
• ✅ Telecom system development (MVNOs, HLR, billing)
• ✅ QA automation pipelines
• ✅ Academic and educational purposes

Prohibited uses:

• ❌ Bypassing Samsung Knox security policies on real devices
• ❌ Fraudulent device registration or insurance claims
• ❌ Impersonating real devices to access carrier services
• ❌ Any form of network-level fraud

Misusing IMEI numbers is a criminal offense under telecommunications law in most countries. Use generated data only in controlled, offline, or sandboxed test environments.

Samsung vs. Other Android Manufacturers: IMEI Differences

Samsung's TAC diversity is unmatched because Samsung releases more distinct hardware variants than any other Android OEM. For enterprise testing scenarios where device-specific behavior matters, using Samsung TAC codes in your test data is more realistic than using generic Android TACs.

Frequently Asked Questions

Can a generated Samsung IMEI pass a carrier IMEI check?

A generated IMEI will pass format validation (15 digits, valid Luhn checksum). It will not pass a live carrier database lookup — because it is not assigned to any real device and not registered in GSMA's EIR. For testing purposes, this is exactly what you want: it validates your format-checking code without polluting real-world IMEI databases.

How do I find the right Samsung TAC code for a specific model?

You can look up Samsung TAC codes in the GSMA's official TAC database (requires registration), or use sites that aggregate publicly known TAC assignments. The Samsung model number printed on the device (e.g., SM-S928B) corresponds to a specific TAC. The region letter (B = EU, U = US unlocked, N = Korea) always maps to a unique TAC.

Do Samsung tablets use the same IMEI format as phones?

Yes, Samsung tablets with cellular connectivity use standard 15-digit IMEI format. The TAC codes are different from phone TAC codes — they fall in Samsung's tablet-specific TAC blocks. If your system handles both phones and tablets, test both TAC families.

Why does my Android emulator always return the same IMEI?

Android emulators return 000000000000000 or a fixed value from TelephonyManager.getDeviceId(). This is intentional — emulators are not real cellular devices. For testing code that processes IMEI values, inject test IMEIs via mock objects or test configuration rather than reading from the emulator hardware.

Is Samsung Knox enrollment possible with a fake IMEI?

Knox Mobile Enrollment (KME) uses IMEI to pre-register devices. In the KME portal, you can upload a CSV of IMEIs before devices arrive. Using generated IMEIs in a staging/sandbox version of your MDM platform lets you test the enrollment flow end-to-end. On production, only IMEIs of real Samsung devices will successfully complete the Knox enrollment process on the actual device hardware.

What happens if two test records share the same IMEI in a database?

IMEI columns in device databases should have a UNIQUE constraint. If you use the same hardcoded test IMEI for multiple records, you will hit a constraint violation and get misleading test results. Always generate unique IMEIs for each test record — a batch generator is the right tool for this.
