Looking for Indian to answer my question

Hi

The first post card that I sent was to Germany and it was the yellow post card. I put additional stamps on it. And it had reached.

That said, it is meant for sending within India only. Additional stamps not requires.

Other cards require stamps - Rs 6 for within India, Rs 10 for Pakistan, SriLanka, Bangladesh, Nepal, Bhutan, and Rs 15 for the rest of the world

For sending in envelope, the prices are different and higher

Hope it helps.
