Create a telephone number allocation so that you can group a set of telephone numbers and apply the required conditions to it by using the Telecommunications Network Inventory application. You can also review, create, update, or delete a telephone number allocation.

## Before you begin

* Ensure that the Telecommunications Network Inventory application includes all the required components of your telephone number. Otherwise, see [Create the components of a telephone number](https://servicenow-prod.fluidtopics.net/bUxTpAa5QpC5jEUtd2oIig "Create a central office code, country code, area code, and rate center for a series of telephone numbers by using the Telecommunications Network Inventory application.").

## About this task

Setting the Create telephone allocations and numbers checkbox as true, while creating
a telephone block, creates individual numbers and telephone allocation. You can
assign multiple telephone numbers to a telephone allocation. When you assign a
single telephone number allocation to a telephone number block, you can assign a
series of numbers to that block.

On completing this task, assigning a single telephone number allocation to a telephone number block results in assigning a series of numbers to that block.

## Procedure

2. Select the list icon (![List icon.]()), and then go to Inventory Number AllocationTelephone Number.
3. Select New.
4. On the Details tab, on the IP address section form, fill in the fields.

   |-|-|
   | Name | Name for this allocation. |
   | Telephone number block | Telephone number block that you want to add the numbers to. Note: For the port-in numbers or the numbers that you don't want to assign a block to, you can create the telephone numbers and telephone allocation without referring to a block. |
   | Availability | Availability of this block. If this block is available, set the availability as true. Also, you can specify how many numbers are under the unassigned status and are available. |
   | Start number | Starting phone number of the series from where you can assign this block to. |
   | End number | Ending phone number of the series that you can assign to this block to. |

   To learn about the other fields, see [Inventory number allocation fields](https://servicenow-prod.fluidtopics.net/aDz1~zcDpFepvPA6bQe_5Q "The inventory number allocation fields enables you to describe the details for LAG, VLAN, IP address, and telephone number records.").
5. Add the attachments, such as the graphics or documents, by selecting the attachment icon (![Attachment icon.]()) in the right panel.
6. Select Save.  
   The related tabs appear on the form. You can view or change the related tab information. To learn more about the related tabs, see [Related tabs in the Network inventory forms](https://servicenow-prod.fluidtopics.net/jACb5lIoDhdHZ6aLqvsTJw "The related tabs in the Network Inventory forms display the related records that dynamically change based on the connection and relationships with the other network assets. You can selectively view, modify, or update these records.").  
   Note:  
   Based on the assigned or allocated telephone numbers, the existing allocation divides into separate allocations. For example, in a series of 1-100, if 1-10 and 90--100 are assigned, then the 1--100 allocation divides into three allocations. The three allocations, 1--10 and 90--100 with availability as No and 11--89 as Yes are created.
