Is it Required to Verify receiver numbers on twilio

Question

I am using Twilio API to send SMS to users .

My question is here that is it required to verify every reciver numver on twilio?

right now its saying for every receiver.

"The number is unverified. Trial accounts cannot send messages to unverified numbers; verify at twilio.com/user/account/phone-numbers/verified, or purchase a Twilio number to send messages to unverified numbers."

Thanks Dalvir

It is only required to verify numbers that you want to send SMS to when your account is in trial mode. If you upgrade your account you will be able to send SMS messages to any number.
