The passport application says "at least one piece of ID" and there is space to fill details of 2 pieces of IDs.
I have my drivers licence and health card. So, I can give 2 IDs if needed. But in my wife's drivers licence there is a small mistake which we are planning to correct next month when it is due for renewal and hence I don't think I should submit that. (Actually, there are two words with a space in her First Name. But these guys have mistakenly put a comma in between. So people can take the second word as a Middle Name. We also noticed it only recently when one guy interpreted it that way. No body else notice or care about it in last five years when it was presented as ID proof ! So, Iam planning to submit only health card for her- which contains all the details they have asked : name, photo, DOB, sex, signature (5 things).
My question is,
Is there any advantage of providing 2 IDs compared to one ID? Or is it sufficient if I give one ID which contain all these 5 things ?
