 * I want to add a field in Ultimate member where is filled in automatically by 
   the system with sequential code, for example: 0001, 0002, 0003, etc.
    or at the
   prefix filled in automatically takes another field value. example: there is a
   field “sex” with a value “Male” and “Female.” Then the contents in the field 
   are: M-0001, M-0002, etc. F-0001, F-0002, etc.
 * How can I achieved it?

 * Hi [@redpages](https://wordpress.org/support/users/redpages/)
 * It’s possible to make the sequential code with javascript/JQuery so that you 
   can use the Sex/Gender value as the prefix key.
 * And then you will need to add a custom field validation to check if the sequential
   code is already in used to avoid duplication and keep the value unique. For more
   details about the Custom Field Validation, please see this doc article: [https://docs.ultimatemember.com/article/94-apply-custom-validation-to-a-field](https://docs.ultimatemember.com/article/94-apply-custom-validation-to-a-field)
