A serial number is a unique, identifying number or group of numbers and letters assigned to an individual piece of hardware or software. Other things have serial numbers as well, though, including banknotes and other similar documents.

The idea behind serial numbers is to identify a specific item, much like how a fingerprint identifies a specific person. Instead of some names or numbers that specify a whole range of products, a serial number is intended to provide a unique number to one device at a time.

Hardware serial numbers are embedded in the device, while software or virtual serial numbers are sometimes applied to the user who will be using the software. In other words, a serial number used for software programs are tied to the purchaser, not that specific copy of the program.

The term serial number is often shortened to just S/N or SN, especially when the word precedes an actual serial number on something. Serial numbers are also sometimes, but not often, referred to as serial codes.

Serial Numbers Are Unique

It's important to distinguish serial numbers from other identifying codes or numbers. In short, serial numbers are unique.

For example, a model number for a router might be EA2700 but that's true for every single Linksys EA2700 router; the model numbers are identical while each of their serial numbers is unique to each particular component.

As an example, if Linksys sold 100 EA2700 routers in one day from their website, every one of those devices would have 'EA2700' somewhere on them and they would look identical to the naked eye. However, each device, when first built, had serial numbers printed on most of the components that are not the same as the others bought that day (or any day).

UPC Codes are common as well but are actually not unique like serial numbers. UPC Codes are different than serial numbers because UPC Codes are not unique to each individual piece of hardware or software, as serial numbers are.

The ISSN used for magazines and ISBN for books is different as well because they're used for whole issues or periodicals and aren't unique for every instance of the copy.

Hardware Serial Numbers

You've probably seen serial numbers many times before. Nearly every piece of the computer has a serial number including your monitor, keyboard, mouse and sometimes even your entire computer system as a whole. Internal computer components like hard drives, optical drives, and motherboards also feature serial numbers.

Serial numbers are used by hardware manufacturers to track individual items, usually for quality control.

For example, if a piece of hardware is recalled for some reason, customers are usually made aware of which particular devices need service by being provided a range of serial numbers.

Serial numbers are also used in non-tech environments like when keeping an inventory of tools borrowed in a lab or shop floor. It's easy to identify which devices need to be returned or which ones have been misplaced because each of them can be identified by their unique serial number.

Software Serial Numbers

Serial numbers for software programs are usually used to help ensure that the program's installation is only performed one time and only on the purchaser's computer. Once the serial number is used and registered with the manufacturer, any future attempt to use that same serial number can raise a red flag since no two serial numbers (from the same software) are alike.

If you're planning on reinstalling a software program you've purchased, you'll sometimes need the serial number to do so. See our guide on how to find a serial key if you need to reinstall some software.

Sometimes, you might find that a software program can attempt to make a serial number for you that you can use to activate a program illegally (since the code wasn't legally purchased). These programs are called keygens (key generators) and should be avoided.

A serial number for a piece of software is not usually the same as a product key but they are sometimes used interchangeably.

Issue:

Error Your Individual Serial Key

Your serial number does not match the product

This error is often displayed as 'Serial Number is invalid.' There are several reasons why this mismatch can occur.

• The serial number is valid but is associated with a different product (e.g., AutoCAD LT 2010 versus AutoCAD 2010).
• The serial number is valid but is associated with a different version of AutoCAD (e.g., AutoCAD 2009 versus AutoCAD 2011).
• The serial number is valid for a network deployment, but you are trying to activate the product as a stand-alone license (and vice versa).

Before registering and activating your license, make sure your serial number matches the product, release, and type of license you purchased. You can request a report that lists information about your product serial numbers, including product, version, and status, by visiting Contact Support - License Reports.

Your serial number is no longer valid

There are several reasons why a serial number may not be valid.

• Your product might have been upgraded to a newer version or cross-graded to a different product.
• The serial number is associated with a product or a release of a product that you are not licensed to use.
• The serial number is obsolete and has been replaced with another serial number to simplify a contract.

Before registering and activating your product, make sure your serial number matches the product, release, and the type of license you purchased.

You entered the serial number for an individual product rather than the collection serial number

If you are activating a product in a collection, make sure you use the serial number and product key for the collection (not the individual product). For more information, see Finding Serial Numbers & Product Keys.

You are trying to activate an ineligible previous version

You can only activate previous versions that are listed on the eligible previous version list for subscriptions or maintenance plans. For more information about when previous versions become ineligible for activation, see Product Support Lifecycle.

Your contact information doesn't match the serial number

The contact information doesn't match what is already associated with the serial number when the product was registered. This can happen if there is a change to your name, the company name, or your address after the product was registered. Keep your contact information up-to-date using Register Once. There, you can add an account with your current information, register products to that account, and delete your old accounts, or those with outdated information.

You've exceeded the activation limit

Activation limits are based on the type of license agreement you have. They are designed to remain compliant with your license and protect you from someone else using your license. (You may receive 'Error 10: Activation Limit Reached' during the in-product activation process.)
