How to Identify Your MacBook Model Before Ordering Replacement Parts

When it comes to repairing or upgrading your MacBook, ordering the correct replacement parts is crucial. Apple has released numerous MacBook models over the years, and many of them look similar at first glance. However, the internal components and specifications can vary significantly. If you’re not sure which MacBook model you own, you risk ordering parts that won’t fit or function properly.

This guide will walk you through the steps to correctly identify your MacBook model before purchasing replacement parts.

Why Identifying Your MacBook Model Matters

Each MacBook generation has unique dimensions, connectors, and hardware configurations. For example, a battery designed for a MacBook Pro (13-inch, 2017) may not be compatible with a MacBook Pro (13-inch, 2020), even though they appear nearly identical. Knowing your exact model number ensures you get the right parts the first time and avoids wasted time or money.

Step 1: Check the "About This Mac" Menu

1. Click the Apple logo in the top-left corner of your screen.

2. Select About This Mac.

3. You’ll see information including:

   • MacBook model (e.g., "MacBook Air (M1, 2020)")

   • Processor type

   • Memory (RAM)

   • Serial number

The model identifier (e.g., MacBookPro15,2) can also be found under the System Report button.

Step 2: Look for the Model Number on the Device

If your MacBook won’t power on, you can still identify it physically:

• Flip your MacBook over. On the bottom case, you’ll find small text near the regulatory markings.

• Look for the model number (e.g., A2337, A1708, A1398).

This “A” number is Apple’s hardware identifier, which directly corresponds to a specific MacBook model.

Step 3: Use Apple’s Official Support Website

Apple provides a support page where you can enter your MacBook’s serial number to confirm its model. Simply visit Apple’s Check Coverage page and enter your serial number. This will show you the official model name and year.

Step 4: Match the Model to the Correct Parts

Once you know your model identifier or “A” number:

• Compare it with the specifications listed by your replacement parts supplier.

• Double-check that the part matches your exact MacBook model and year.

For example:

• Battery for MacBook Pro A1398 (2015) is not compatible with MacBook Pro A1708 (2017).

• Keyboards, screens, and trackpads also differ between models and years.

Final Tips

• Always verify twice before ordering.

• When in doubt, contact the supplier and provide your model number.

• Consider genuine Apple parts or certified third-party components for reliability.

Correctly identifying your MacBook model will save you time, money, and frustration—ensuring your repair goes smoothly.
