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.

555 Number Characteristics

• 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

555 Number Limitations

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

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

4. Stop using the 555 number

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

Message history cannot be transferred from the 555 number to the regular phone number by 360dialog. We do not provide any synchronization functionality between different phone numbers.

Billing and refunds

• 555 numbers are charged as regular numbers at standard rates.

• 360dialog does not sell 555 numbers at any additional cost.

• Any usage charges incurred are subject to WhatsApp pricing terms.

• We do not issue refunds for 555 numbers that were onboarded by mistake.

  • Any 555 numbers that are registered will be billed in the same way as regular phone numbers.

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.
