How can I confirm the exact model number of a Samsung device?

When buying, selling, or troubleshooting a Samsung smartphone, confirming the exact model number is one of the most important steps. Samsung produces a wide variety of devices under the same series name, and each region or carrier variant might have a slightly different model number. Knowing your exact model can help you find compatible accessories, get accurate software updates, and ensure that you’re buying or selling the right product.

In this comprehensive guide, we’ll walk you through how to check the exact model number of any Samsung device—from smartphones and tablets to wearables. We’ll also explain why it’s important, how to tell the difference between model and serial numbers, and what you should know if you’re purchasing a refurbished Samsung phone such as the Refurbished Samsung S22 Ultra 5G, Refurbished Samsung S23 Ultra 5G, Refurbished Samsung S24 Ultra, or Refurbished Samsung S24 5G Ultra.

Why It’s Important to Know the Exact Model Number

Before we get into how to find it, let’s look at why the model number matters so much.

1. Software Updates:Samsung releases updates based on device model and region. If you know your model number, you can check whether a new Android or One UI version is available for your device.

2. Compatibility:Accessories like phone cases, screen protectors, and chargers are often model-specific. The S22 Ultra, for instance, has slightly different dimensions compared to the S23 Ultra, even though they belong to the same series.

3. Repairs and Spare Parts:When repairing or replacing parts (like the display or battery), knowing the exact model ensures you get the right components.

4. Buying or Selling Devices:If you’re buying a refurbished phone, the model number verifies authenticity. Reputable sellers like EasyPhones always list the exact model, helping you make a confident purchase.

Where to Find the Model Number on a Samsung Device

Samsung makes it quite easy to locate your model number. There are several reliable ways to find it, depending on whether your phone is turned on, or even if it’s not.

1. Check in the Settings Menu

The easiest way to find the model number of your Samsung device is through the Settings app.

Steps:

1. Open the Settings app on your Samsung phone or tablet.

2. Scroll down and select About phone (or About device on older models).

3. You’ll see details such as:

   • Model name (e.g., Galaxy S23 Ultra)

   • Model number (e.g., SM-S918B/DS)

   • Serial number

   • IMEI number

If you only see the model name at first, tap on Model number—some devices show a shortened name like “Galaxy S23 Ultra,” but tapping reveals the full code.

2. Check on the Device Box or Invoice

If you still have the original box or purchase receipt, you’ll find the model number printed near the barcode or product information label. For example:

Model: SM-S908E/DS

This code tells you that the phone is a Galaxy S22 Ultra, dual-SIM variant for a specific region.

Checking the packaging is especially useful if the phone won’t power on or has a damaged screen.

3. Look Under the Battery (Older Models)

For older Samsung models with removable batteries, the model number is printed beneath the battery.

1. Turn off the device.

2. Remove the back cover and battery.

3. Look for a small label that lists “Model” followed by a code such as SM-G950F.

4. Check Using the Dialer Code

Samsung devices have a secret dialer code to display system information quickly.

Steps:

1. Open the Phone app.

2. Dial *#06# to display your IMEI and sometimes the model number.

3. For some devices, use *#1234# to view the PDA, CSC, and MODEM versions, which correspond to firmware and model details.

This method is perfect if you need a quick confirmation without going deep into settings.

5. Use Samsung Members App

If you have the Samsung Members app installed:

1. Open the app and go to Support.

2. Tap on Device Info.

3. The app will show your device’s model name, number, software version, and more.

This is particularly useful for verifying authenticity and warranty information.

Understanding the Samsung Model Number Format

A Samsung model number might look complicated, but it follows a specific pattern.Let’s decode an example:

SM-S918B/DS

• SM – Stands for Samsung Mobile.

• S918 – Identifies the specific model (in this case, Galaxy S23 Ultra).

• B – Indicates the region or processor type (Exynos or Snapdragon).

• /DS – Means “Dual SIM.”

This helps you understand what variant you have—important for network compatibility and firmware updates.

Model Number vs. Serial Number vs. IMEI

Many users confuse these three identifiers. Here’s how they differ:

Identifier	Purpose	Example
Model Number	Identifies the device series and variant	SM-S918B
Serial Number (S/N)	Unique identifier for each unit	R5CT40AB123
IMEI	Identifies the mobile device on cellular networks	352394826123456

The model number is what you need to confirm the exact version of your Samsung device, while the IMEI is used for network registration, and the serial number is mainly for warranty and service tracking.

What If You’re Buying a Refurbished Samsung Device?

When buying a refurbished or renewed Samsung smartphone, verifying the exact model number is essential to ensure you’re getting the right variant and features. Sellers like EasyPhones specialize in certified refurbished Samsung devices that look and perform like new, complete with warranty and quality checks.

For example, if you’re considering upgrading to a premium phone at a lower price, check out:

• Refurbished Samsung S22 Ultra 5G – Offers incredible performance and camera quality at a fraction of the original cost.

• Refurbished Samsung S23 Ultra 5G – Features the latest Snapdragon processor and an advanced 200MP camera system.

• Refurbished Samsung S24 Ultra – Boasts cutting-edge AI tools and improved battery life.

• Refurbished Samsung S24 5G Ultra – Combines ultra-smooth performance with next-gen connectivity.

Each listing includes the exact model number, which helps confirm you’re getting the genuine product with all the expected features.

Tips for Verifying Authenticity

1. Cross-check the model number online.Visit Samsung’s official website or trusted sellers to ensure your model number matches the specifications listed.

2. Avoid mismatched packaging.The model number on the device, box, and settings should all match. If they don’t, it could indicate tampering or a replacement unit.

3. Check warranty information.Enter your model and serial number on Samsung’s support site to confirm warranty coverage.

4. Inspect software version.Go to Settings → About phone → Software information to verify the One UI and Android versions are appropriate for your model.
