We do not store individual Member numbers for plans, but we have a suggestion for adding it to the employee homepage.
If you would like to add a member ID number you may do so by adding this as a Note to an employee’s individual record. If you pull up an employee's record you will see "add a note" by the employees name. You can mark the subject as Member ID# and then document the number in the note section. This provides you with the ability to note different ID numbers associated with several plans and also allows you to make this only visible to the specific employee under the 'notes' section of their homepage.
