do I need to enter all petition numbers in DS160 for H1B?

Hi,

Company A sponsored h1b for me. Before getting stamping on my passport, I changed job and new company B transferred my h1b. Hence there was one petition number for company A’s petition and another petition number for company B’s petition.

Now i am filling out DS 160. My question is do i need to enter both petition numbers in my DS 160? OR do i need to enter only one petition number in DS 160 which would be the petition number of company B (my current employer).

Please help! Thanks in advance.
