How Do I Determine My Maple Purchase Code?

There are a few ways to determine your Purchase Code:

Inside the "Order Confirmation" email or "Information about your Maplesoft Entitlement" (If you are an EMP customer) e-mail from Customer Service. Your Purchase Code should be given in the following section.

Note: The order confirmation or Entitlement e-mail is sent to the e-mail address of the person who purchases Maple.
Note 2: If you have EMP your Order Confirmation won't contain your purchase codes. They will be sent each year with your Entitlement e-mail.
For students who received Maple through a promo code or access code you'll be able to find the purchase code in the "Your Maple Student Edition Order" email. In the following section.
If you already have Maple installed and activated you can find your purchase code one of the following ways:
- Executing the following code inside Maple:
```
kernelopts( license[serial] );
```
- The Purchase Code should be mentioned on the "About Maple" page:
```
"Help" > "About Maple".
```
- Inside either the readme.txt or soapfile.dat files located in:
  Windows:
```
C:\Program Files\Maple 2019\license
```
  Mac:
```
/Library/Frameworks/Maple.framework/Versions/2019/license/
```
  Linux:
```
$HOME/maple2019/license/
```
  For License servers these files can be found in:
  Windows:
```
C:\Program Files\Maple Network Tools\activate
```
  Mac:
```
$HOME/Applications/Maple_Network_Tools/activate/
```
  Linux:
```
$HOME/MapleNetworkTools/activate
