# What's the difference between single-use codes and validation codes

The main difference is that single-use codes are meant for secure and unique distribution while validation codes are meant for secure validation.  
  
*   Single use codes
  
  
"Single use" security mode.  
Single use codes have a unique coupon URL for every consumer. e.g. digicpn.com/p/abcdef/1234567890  
These coupons can only be accessed via the entire URL and can only be validated once.  
Those single-use codes have nothing to do with validation, but with distribution.  
  
There are 4 ways to work with single-use codes  
  
*   Landing Page Integration
  
  
The landing page distribution method simplifies the approach. Enable single-use mode for your coupon and the landing page automatically assigns unique single-use access URLs for every distributed coupon. [Have a look at the article](https://help.coupontools.com/en/article/how-to-launch-single-use-digital-campaigns-via-my-landing-page-1iiuua2/) for more information.  
  
*   Single-use code generator
  
  
This feature is located at the integrations tab or at the launch section of your coupon. You can generate batches of 10 000 unique single-use coupon codes that you can export to a CSV file.

Keep in mind that the single-use code generator is an on request feature. [Get in touch with the support team](https://www.coupontools.com/en/get-in-touch) to ask for access.  
  
*   SMS
  
  
Send out single-use coupons through SMS. Simply add the coupon to your message and a unique single-use access URL is automatically generated for every recipient.  
  
*   Directory
  
  
It is possible to publish single-use coupons in a coupon directory. [More information about the setup can be found here.

The Directory is only available in the Silver or Gold plan.  
  
*   Validation codes
  
  
You can import or generate validation codes which are displayed on the coupon. The cashier enters the unique code into their validation app or widget for successful validation.
