Departed Whiteman (WHP) Airport to [destination] Airport going by Van Nuys (VNY) Airport. Climbed to 2;450 feet and I believed Whiteman Tower cleared me through Van Nuys airspace so I contacted approach on for flight following. Radio contact was made with approach and they asked me to squawk 1200 and ident which I complied. All this time I remained at 2;450 feet. I then was able to squawk the correct squawk code and radar contact was made. Thereafter I climbed to 4500 feet and proceeded on my route. SoCal requested that I contact Van Nuys tower after I landed; which I did. Van Nuys tower told me that I had flown through their departure area. I explained to Van Nuys that I thought I was cleared through Van Nuys airspace by Whiteman so I had contacted SoCal.Prior to departure; confirm the correct sequence of who I should contact and when I should contact them. Always confirm I have clearance through Van Nuys airspace when departing Whiteman.
An aircraft departed WHP and mistakenly thought it had clearance to fly through VNY airspace. Aircraft penetrated VNY airspace without proper clearance.
