Where to find your MacBook model number
Your MacBook's model number appears in two places: on a sticker underneath the machine, and in the system information menu on the screen. The sticker is fastest if you can flip the laptop over. The menu route works if the sticker is worn or missing, and it also shows you other hardware details at the same time.
The sticker location depends on your MacBook's age. On newer models (2016 and later), look on the bottom case near the center or toward one corner. On older MacBooks, the sticker is usually near the hinge or along the edge. The model number starts with "A" followed by four digits — for example, A2141 or A1989.
If you cannot see the sticker clearly or prefer not to flip the machine over, the system menu takes about 30 seconds and shows you the exact model name as well.
Key Takeaways
- The model number is a sticker on the bottom of your MacBook starting with "A" and four digits, like A2141.
- You can also find the model number by clicking the Apple menu, selecting "About This Mac", and reading the "Model Identifier" line.
- The model number is different from the serial number — the serial number is longer and appears on the same sticker.
- Knowing your model number helps you find the right charger, replacement parts, repair guides, and technical specifications for your exact machine.
Using the sticker on the bottom
Turn your MacBook upside down on a soft surface so the screen faces down and the bottom is visible. Look for a white or silver sticker near the center of the case or toward one corner. The sticker contains several lines of text in small print.
Find the line that starts with "Model" or "Model No." The number next to it is what you need — it will be the letter A followed by four digits. Write this down or take a photo of the sticker so you have it saved. The same sticker also shows your serial number, which is a longer alphanumeric code you may need for warranty or repair purposes.
If the sticker is faded or unreadable, do not try to clean it with liquid — use the system menu method instead.
Finding it through the system menu
Click the Apple logo in the top-left corner of your screen. A dropdown menu appears. Select "About This Mac" from the list.
A window opens showing your MacBook's information. Look for the line labeled "Model Identifier" — this is the technical model number. You will also see "Model Name" above it, which tells you the friendly name like "MacBook Pro" or "MacBook Air" and the screen size.
The Model Identifier line shows something like "MacBookPro16,2" or "MacBookAir10,1". This is the same information as the sticker, just in a different format. Either format works for finding parts, support documents, or technical specifications online.
What the model number tells you
Your model number is the key to finding the right accessories and information for your specific machine. Different MacBook models use different chargers, RAM types, and storage configurations, so knowing your exact model prevents you from buying incompatible parts.
The model number also helps you find repair guides, warranty information, and technical specifications. When you contact Apple Support or a repair shop, they will ask for this number to understand what you own and what options are available for your machine.
Model number versus serial number
The model number and serial number are two different things on the same sticker. The model number is short (A followed by four digits) and tells you what type of MacBook you have. The serial number is much longer and unique to your individual machine — no two MacBooks share the same serial number.
You need the model number to find parts and technical information. You need the serial number for warranty claims, repairs, or if your MacBook is lost or stolen. Both appear on the bottom sticker, and both also appear in the "About This Mac" menu under different labels.
If you cannot find the sticker
Stickers wear off or peel away over time, especially if your MacBook has been used for several years. If the bottom sticker is missing or completely unreadable, the system menu is your reliable backup. The "About This Mac" window shows the model information even if the physical sticker is gone.
You can also check your original purchase receipt or the box your MacBook came in — both usually print the model number. If you bought the machine from Apple, your account on apple.com shows the model under "My Devices" or your purchase history.
Using the model number to find what you need
Once you have the model number, you can search for chargers, replacement batteries, screen protectors, and repair parts specific to your machine. Search the model number on the manufacturer's website or on retail sites to see what is compatible.
The model number also helps you find the right support documents and troubleshooting guides. Apple's support website lets you search by model, and third-party repair guides often organize instructions by model number so you get steps that match your exact hardware.
Frequently Asked Questions
Is the model number the same as the serial number?
No. The model number (like A2141) tells you what type of MacBook you own. The serial number is a longer code unique to your individual machine. Both appear on the bottom sticker, but they serve different purposes — the model number for parts and specs, the serial number for warranty and ownership records.
Can I find the model number if my MacBook won't turn on?
Yes. The sticker on the bottom is always readable without powering on the machine. Flip your MacBook over and look for the white or silver sticker with the model number printed on it. You do not need the screen or system menu to read the physical sticker.
What if the sticker says "Model A" but I see a different number in "About This Mac"?
They are the same model in different formats. The sticker shows the short code (A2141), and "About This Mac" shows the technical identifier (MacBookPro16,2). Both refer to the same machine. Use whichever format works best for your search.
Do I need the model number to get repairs?
Yes. Repair shops and Apple Support use the model number to understand your machine's hardware, find the right replacement parts, and give you accurate pricing and timelines. Have the model number ready before you contact them.
Where exactly is the sticker on older MacBooks?
On MacBooks from 2015 and earlier, the sticker is usually near the hinge on the bottom case or along one of the edges. On 2016 and newer models, it is typically centered or toward one corner. If you cannot find it, the "About This Mac" menu works on any MacBook that powers on.
