Meta Provided (555) Phone Numbers

This page describes Meta 555 Business Phone numbers.

During Embedded Signup to the WhatsApp Business Platform, Meta may offer eligible businesses the option to add up to two 555 business phone numbers.

These numbers are issued directly by Meta and can be used on the WhatsApp Business Platform under specific conditions.

Key characteristics of 555 numbers

555 business phone numbers:

• Use the US country calling code (+1) with a 555 area code

• Are automatically verified by Meta

• Behave like standard WhatsApp Business phone numbers in terms of:

  • Pricing rules

  • Quality ratings

  • Messaging limits

• Require display name approval before messages can be sent

• Cannot be migrated to another WhatsApp Business Account

• Cannot be used outside of the WhatsApp Business platform

For Meta’s official documentation, see: Embedded Signup

Important limitations to be aware of

While 555 numbers can technically send and receive messages, they have important restrictions:

• They are non-portable and cannot be transferred to another WABA

• Any configuration, history, or setup linked to a 555 number cannot be moved to another phone number

• Once stopped, a 555 number should be considered disposable

• They are not suitable for long-term production use where number ownership, portability, or future migration is required

555 numbers are issued and managed by Meta. They are not provided, owned, or controlled by 360Dialog.

Recommended use cases

555 business phone numbers are best suited for:

• Initial onboarding and platform evaluation

• Integration testing and demos

• Internal QA and proof-of-concept setups

For live, customer-facing, or long-term usage, a regular business phone number is strongly recommended.

Switching from a 555 number to a regular phone number

Steps

1. Prepare a new phone number

   • Must be able to receive SMS or voice calls

   • Must not already be registered with WhatsApp

2. Add and verify the new phone number

   • Complete the standard verification process

   • Add the number to the same waba to be able to use the same templates

3. Reconfigure setup

   • Update webhooks, integrations, and messaging configuration

   • Re-submit message templates if required (in case a new waba was created)

4. Stop using the 555 number

   • Any data, balances, or setup associated with the 555 number cannot be transferred

Billing and refunds

• 555 numbers are issued by Meta

• 360dialog does not sell or manage these numbers

• Any usage charges incurred are subject to Meta’s pricing rules

• Refunds related specifically to the 555 number itself are not applicable

Best practice

Use 555 business phone numbers only for testing, evaluation, or short-term onboarding.

For production environments, always onboard with a regular business phone number to avoid reconfiguration effort, migration limitations, and long-term operational constraints.
