I just received the new style blue colored adsense check. it has nothing written on the back side. Do I have to sign on the back side before I deposit it? The older checks were green and had a box behind them.
It is basically a standard citibank check. Similar to the picture below. But it is printed on edge of a full paper like before.
Do the same things you used to do on your older checks. i.e. Signature, Name and Account and your mobile number as well.
