- Under Area code, select an area code.

Select the numbers you want. You have 10 minutes to select your phone numbers and place your order. If you take more than 10 minutes, the phone numbers will be returned to the pool of numbers.

The number of phone numbers for users (subscribers) is equal to the total number of Domestic Calling Plan and/or Domestic and International Calling Plan licenses you have assigned multiplied by 1.1, plus 10 additional phone numbers. For example, if you have 50 users in total with a Domestic Calling Plan and/or Domestic and International Calling Plan, you can acquire 65 phone numbers (50 x 1.1 + 10). For details, see How many phone numbers can you get?. If you need to get more phone numbers than this, contact Support Contact for Business Products - Admin Help.
