 When using multiple questionnaires for every completed questionnaire a new dataset (data row) is stored. For matching reasons every data row needs a distinct participant code. By doing the following one can get such a code: When using multiple questionnaires for every completed questionnaire a new dataset (data row) is stored. For matching reasons every data row needs a distinct participant code. By doing the following one can get such a code:
-  * If you send mailings, SoSci Survey automatically stores a distinct personal identification under the variable SERIAL (additional variable in the data output). This is possible also without losing any anonymity. Important: The email must contain the placeholder %link% in order to actually send personalized links.  +  * If you send mailings, SoSci Survey automatically stores a distinct personal identification under the variable SERIAL (additional variable in the data output).

-  * You can send personalized links on your own. The identification of every participant then will be passed by a reference or a serial number (see also [[en:survey:url|URL to the Questionnaire]]). A reference will be stored under the variable REF, a serial number will be stored in the variable SERIAL (this one also allows for continuing the questionnaire). +    * **Important:** The email must contain the placeholder %link% in order to actually send personalized links. 
 +    * **Important:** All questionnaires must be created within the same survey project. The personal IDs are specific for each project.

A reference will be stored under the variable REF, a serial number will be stored in the variable SERIAL (this one also allows for continuing the questionnaire). 
   * The participants are asked to create a personal code and enter this to a text gadget (for example with the first letter of their mother's name, the last digit of their birth year and so on). Because of its susceptibility to errors we do not recommend this option. If you want to use such an option it is important to ask the single components of the code in distinct, single text gadgets.   * The participants are asked to create a personal code and enter this to a text gadget (for example with the first letter of their mother's name, the last digit of their birth year and so on).
