I am the primary applicant in my Express entry application and my wife is the dependent. We have both received individual and different UCI. While mine is of the common format 1111xxxxxx my wife’s UCI begins with 88 and is an 8 digit number. We have obtained her UCI number from our profile on the CIC website. Could someone please explain why hers does not follow the usual format?? It is also not being accepted as valid when we are trying to register for the Plan for Canada program. Any help would be highly appreciated
