Anyone know how long usually it takes the phone number activated?

Hi, I'm a newbie here.

I purchased the Zoom Phone plan today and selected a number, but it is still pending activation. I checked online, and it said it usually takes no more than 2 hours, but it's been half a day now, and it's still not working.

I wonder what I should do, or is this actually normal? I would appreciate it if anyone could share their experience with me. Thank you!
