How to Find Phone Model from IMEI: Step-by-Step Guide

You have a 15-digit IMEI number in front of you — maybe from a device you are considering buying, a trouble ticket, or an insurance claim — and you need to know exactly which phone it belongs to. The good news: the IMEI contains everything you need to identify the brand, model, and even the chipset of any mobile device. This guide walks you through the process step by step.

What Is an IMEI and Why Does It Identify a Device?

The IMEI (International Mobile Equipment Identity) is a unique 15-digit number assigned to every mobile radio module. It serves as the hardware fingerprint of a device, distinguishing it from every other phone on the planet. No two devices share the same IMEI.

The IMEI is structured as follows:

Segment	Digits	Purpose
TAC (Type Allocation Code)	1—8	Identifies the manufacturer and model
SNR (Serial Number)	9—14	Unique unit identifier
Check digit	15	Integrity validation via the Luhn algorithm

The critical piece for model identification is the TAC — the first eight digits. This code is assigned by the GSMA to each manufacturer for every commercialized device model. When you decode the TAC, you decode the device.

For a deeper explanation of the IMEI structure, see our dedicated article: What is an IMEI?

The TAC: The Key to Model Identification

The Type Allocation Code is a standardized 8-digit prefix maintained in the GSMA TAC Database. Each TAC corresponds to a specific combination of manufacturer, model name, and device variant. For example, a TAC beginning with 35345678 might correspond to a Samsung Galaxy S24, while 35161113 could map to an Apple iPhone 15 Pro.

This means that even without holding the physical device in your hands, you can determine its exact identity from just eight digits. The TAC system is what makes IMEI-based identification possible at scale — it is the same mechanism used by mobile operators, regulators, and law enforcement agencies worldwide.

Step 1: Find Your IMEI

Before you can identify a device, you need its IMEI. Here are the most reliable methods:

Dial *#06#

This universal USSD code works on every GSM, LTE, and 5G phone. Simply open the dialer and type *#06#. The IMEI is displayed on screen immediately. If the device has two SIM slots, both IMEIs are shown.

Check Device Settings

• Android: Navigate to Settings > About Phone > Status > IMEI Information
• iOS: Go to Settings > General > About, then scroll down to the IMEI field

Other Sources

• Original packaging: The IMEI is printed on the barcode label of the retail box.
• SIM tray: On some devices (notably iPhones), the IMEI is engraved on the SIM card tray.
• Google account: Visit google.com/android/find to see the IMEI of Android devices linked to your account.

Write down the full 15-digit number carefully. Transcription errors are common, and even a single wrong digit will return incorrect results.

Step 2: Extract the TAC (First 8 Digits)

Once you have the IMEI, isolate the first eight digits. This is the TAC.

Example:

• Full IMEI: 353456789012345
• TAC: 35345678

The remaining digits (serial number and check digit) identify the individual unit, but they are not needed for model identification. The TAC alone tells you what the device is.

Step 3: Use the HiCellTek TAC Lookup Tool

Now that you have the TAC, you can look it up instantly using the HiCellTek TAC Lookup tool. The process is simple:

1. Go to the TAC Lookup page
2. Enter the 8-digit TAC (or the full 15-digit IMEI — the tool extracts the TAC automatically)
3. View the results

The tool performs real-time validation as you type and returns results in milliseconds.

What Information You Get from a TAC Lookup

A TAC lookup through HiCellTek returns detailed device specifications, not just a brand name. Here is what you can expect:

• Brand and manufacturer: The company that produced the device (e.g., Samsung, Apple, Xiaomi, OnePlus)
• Model name and number: The exact commercial name and internal model identifier
• Chipset: The system-on-chip powering the device (e.g., Qualcomm Snapdragon 8 Gen 3, Apple A17 Pro, MediaTek Dimensity 9300)
• Supported network bands: Which LTE and 5G NR frequency bands the device supports
• Network technology: Whether the device supports 2G, 3G, 4G LTE, 5G NSA, or 5G SA

This level of detail goes far beyond simple brand identification. For telecom professionals, the chipset and band support information is particularly valuable for diagnostic compatibility and network planning purposes.

Practical Use Cases

Buying a Second-Hand Phone

Before purchasing a used device, verify its IMEI against the TAC database. This confirms that the seller’s description matches the actual hardware. A phone advertised as a “Galaxy S24 Ultra” should return exactly that model from the TAC lookup. If the results do not match, walk away.

Insurance Claims

Insurance providers frequently require device identification by IMEI during claims processing. A TAC lookup provides objective, verifiable proof of the device model, which simplifies claim validation and prevents fraudulent substitution.

Network Diagnostics and Drive Testing

For RF engineers and field technicians, knowing the chipset is essential before deploying a device for network testing. Qualcomm-based devices support the DIAG protocol used by most drive test tools, while Exynos or MediaTek devices may not. A quick TAC check prevents compatibility issues in the field. For professionals needing bulk lookups, HiCellTek also provides API access for automated verification.

Enterprise Fleet Management

Organizations managing hundreds or thousands of mobile devices can use TAC lookups to inventory their fleet by model and chipset. This is critical for planning software rollouts, network band compatibility assessments, and hardware refresh cycles.

Frequently Asked Questions

Can I identify a phone model from a partial IMEI?

You need at least the first 8 digits (the TAC) to identify the model. The remaining 7 digits identify the individual unit and the check digit. If you have fewer than 8 digits, model identification is not possible.

Is the IMEI the same as the serial number?

No. The IMEI is a network identifier regulated by the GSMA, while the serial number is a manufacturer-assigned identifier. They serve different purposes and have different formats. Our article on IMEI vs TAC vs Serial Number explains the distinction in detail.

Does a TAC lookup reveal if a phone is stolen?

No. A TAC lookup identifies the device model based on the manufacturer and model code. It does not check blacklist or stolen device databases. Blacklist verification requires a different type of service that queries carrier EIR (Equipment Identity Register) databases. For more about stolen device verification, see our guide on using the IMEI to block a stolen phone.

Do dual-SIM phones have two different TACs?

In most cases, both IMEIs on a dual-SIM device share the same TAC because they belong to the same device model. The serial number portion (digits 9—14) differs between the two IMEIs, but the TAC (digits 1—8) is typically identical.

Is the TAC Lookup tool free?

Yes. The HiCellTek TAC Lookup tool is free for individual queries. For high-volume or automated lookups, an API is available for professional use — see the API documentation for details.
