You need to ask the embassy (or agency) that is processing your visa. They may require you to pick it up within a few days - or they may offer to courier it to you.
The rules will differ based on the embassy / agency used; thus you need to ask.
If your concern is the validity of the visa, then it is valid from the dates listed on the visa; which should be inline with the dates you mentioned in your itinerary when you applied.
