I am having so many problems trying to link the application for my wife's residence permit to a GCKEY account. It is her account, we put in all information as it is in the documents we sent but nothing works. We have followed all the tips and even contacted support but nothing works. The strange thing is we have received documents that have her UCI in the form 1234-5678, my UCI is very different. On the site, when you have to put the UCI in, it shows you the format should be 1234-5678 but when we put her number in, it gives an error and says the number is not valid. Has anyone experienced anything similar?
