are you sure your inputs are correct?
LC2 application number total 10 digits, like mine, starts with a letter i.e E000166XXX
the birth date must be in correct order as you input, to wit : month-date-year
then yours and your LC2 surname/family name
then place/country of birth
if still your LC2 Ecas will not show it is most probable it is not entered yet into the ecas system, you can try to email cpcv and inform them of this matter.
