(to Mod please move this if it's not in appropriate spot. I couldn't choose "This discussion is for learning Spanish" )

I am trying to send a parcel to someone in Spain for a surprise, but there are a few "???" in the address I just noticed.

for example, there is this  "bj"  (for example, in the address it says "bj.5"

also "urb."

It must be some sort of abbreviation and I can just write it as it is but I just would like to know what they exactly mean.

I have Googled too but thought to come here for quick response.

Thanks guys!
