Company closed - not able to contact any of my previous colleagues for verification

I worked in a company for 2.2 years and joined in an MNC and worked for 5.8 years. I have resigned and took break for 2 years. Now planning to join the same MNC which I left. Recently I heard that my first company got closed. What shall I do now. I have all the details and submitted to this MNC previously and the verification is successfully at that time as the company is working. But now it got closed. I was not able to contact any of my previous colleagues.
Can I join the MNC or will there be any problem?

Dear Anony,
If this is the case, you can join the MNC. For background verification, you can provide the appointment & experience letter, along with Form 16 and bank statement showing salary credit. Company closing down wont affect your career as long as service records are legit in nature.

Can i inform the same to HR. I have experience certificate, playslips, relieving letter of my previous company. I don't have form 16.

Is this resolved? Did you ask any additional documents to prove?
