What is the White Label API Integration?
#
The White Label API Integration allows you to build a completely branded phone number marketplace using NumberBarn's inventory and APIs. Your customers search, purchase, and manage phone numbers through your website while remaining entirely within your brand experience.
Who is the White Label API Integration designed for?
#
The White Label API is best suited for:
  • Established telecom providers
  • Experienced brokers
  • VoIP providers
  • CRM platforms
  • Domain registrars
  • Companies with development resources
This model is ideal for businesses that want full control over the customer experience and are prepared to manage billing, support, and activation workflows.
Will my customers know they are purchasing through NumberBarn?
#
No. The White Label integration allows you to create a fully branded experience. Your customers interact exclusively with your website, checkout process, emails, and support team.
How does the White Label purchase process work?
#
A typical purchase flow looks like this:
  1. Customer selects a phone number on your website.
  2. Customer completes checkout using your payment processor.
  3. Payment is verified.
  4. Your application calls the Create Telephone Numbers API endpoint.
  5. The number is purchased and added to your broker account.
  6. You pay the outstanding balance owed to NumberBarn.
  7. You provide the customer with their porting credentials.
This allows you to completely own the customer relationship from beginning to end.
Can I set my own phone number pricing?
#
Yes. Unlike the Embedded Search tool, the White Label API gives you complete control over pricing. You can add any markup, discount, or pricing strategy you choose before displaying numbers to customers.
