Entering Samsung Codes on the Galaxy S4 - Verizon
You shouldn't trust such a list of secret codes, simply because secret codes are not only device specific but mostly app specific.  

Secret Codes are generally defined by the applications installed on the device.
If you want to have a valid list of secret codes available on your device, you should use an automated secret codes crawler.

I recently developped an Open Source app that crawls AndroidManifest.xml files on your device to found secret codes, and allows you to execute the secret codes available on your device.
You can get it on the Play Store or on the GitHub repository Android-Secret Codes.

But keep in mind that sometimes, secret codes are just executing themselves silently (without visual hint)
