As an admin, you might get an email telling you that some of your requested phone numbers are ready. This article explains why you might not get all the numbers that you initially requested at once and what to expect.
You might have requested a certain number of phone numbers from your carrier. When the phone numbers are ready, you'll get an email telling you how many of your requested phone numbers are ready to use. If the email shows fewer phone numbers than you requested, the remaining numbers will be available soon.
Why you might not get all your numbers at once
Carriers don't always make all phone numbers available at the same time. They often come in batches. Keep an eye on your inbox. Google will notify you as soon as the remaining phone numbers are ready.
