CP site code vs Site code

There is a code field on the Sites page. Also, you can add codes for sites on the CP page. End users often get confused between the two.

The CP site code is a unique code per site within the CP. The Site code is a system-wide code assigned for the site.

Below are some uses of these codes:

Site code:

  • Container label and PPID formats
  • SPR report loading

CP Site code:

  • Barcoding in multi-site clinical studies

Example: To generate PPID automatically with protocol-specific site code. 

  • Set PPID format under 'Label Format and Print Settings' using 'CP_SITE_CODE' token. (e.g. “%CP_SITE_CODE%_%CP_UID(4)%”). Refer ‘PPID label format’ for details on tokens.
  • Add CP specific site code on CP page


  • When a participant is registered to this CP, PPID will be generated based on CP site code as below
