### How to Purchase a Phone Number
Follow these steps to purchase a phone number from NLPearl.AI:
Start by clicking your **profile card** (1) at the bottom-left corner of the sidebar. This opens the Settings panel.
From there, go to the **Phone Numbers tab** (2) to manage or purchase phone numbers linked to your account.
In the **Phone Numbers** tab, locate the **Purchase NLPearl Phone Number** button in the center of the screen.
Click it to access the list of available phone numbers for purchase.
Once you click **Purchase NLPearl Number**, a side panel titled **Purchase Phone Numbers** (1) opens on the right.
Here, you’ll see a list of available US phone numbers. To add a number to your cart, simply click the **Add** button next to it. When selected, the button turns green and updates to **Added** (2).
**Not finding a number you like?** You can refresh the list to generate a new selection of available phone numbers.
Once you’ve selected your numbers, scroll to the bottom of the **Purchase Phone Numbers** panel to access your **Cart**.
There, you’ll see the phone numbers you’ve added, along with the monthly pricing details.
* To remove a number, click the **red delete icon** next to it.
* The **Total** cost is automatically updated based on your selections.
When you're happy with your selection, click the **Purchase** button at the bottom of the panel to finalize your order. Your selected phone numbers will be instantly added to your account — ready to use without any delay.
After purchasing, you can assign phone numbers directly to your **inbound** or **outbound campaigns** from the platform.
To assign a phone number, open the settings of the specific campaign (inbound or outbound) and choose the number you'd like to attach.
If a phone number is scheduled for deletion but still linked to an active campaign, that campaign will **automatically stop working** once the number is removed.
If you no longer need a phone number, you can schedule it for deletion directly from your settings.
Start by going to the **Phone Numbers** section in your Settings. From there, locate the number you want to remove and click the **Delete** button next to it.
A confirmation step will appear to make sure you really want to delete the selected number. Once confirmed, the deletion is scheduled but not immediate.
Once confirmed, the deletion will be scheduled but not immediate. The phone number remains active until its **billing anniversary date**, when it will be automatically removed from your account.
You can continue using the number normally until that date — deletion only takes effect on its billing anniversary.

### Payment and Billing
Phone numbers are billed on a monthly basis. There are two types of payment methods:
| Method | Description |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Credit** | If you have enough credits available in your NLPearl account, phone numbers will be **automatically purchased using those credits**. The total cost will simply be deducted from your current credit balance — no additional action needed. |
| **Credit Card** | If your credit balance is **insufficient**, the system will automatically switch to your **saved credit card** to complete the purchase. Once the transaction is processed, you'll receive an invoice by email. |
**Subscription Inclusions**:
If your subscription plan includes phone numbers and you have not yet used your included allowance, the purchase will be free for the number of phone numbers included in your plan.
***
### Important Considerations
* **Monthly Billing Cycle**: Phone numbers are billed on a monthly cycle starting from the date of purchase.
* **Country Code Limitations**: Currently, only US phone numbers are available for direct purchase. For other countries, consider alternative integration options.
* **Payment Methods**: Ensure your account has sufficient credits or a valid credit card on file to avoid interruptions in service.
