Hello ​@nilay 

Slido doesn't collect participants phone numbers. However, you can use survey, open text poll or Q&A to collect any details you’d need from participants. 

Alternatively, you can enable the option to require participants names when they join. You can even require an email address as well. Find out more in our Community guide here. 

I hope this helps and answers your question! 

All the best,

Hi Kat,

Thanks a lot for that info….
