Can I keep my phone number when changing VoIP operator?

Changing an IP telephony or VoIP operator often raises an important concern: keeping your existing phone number. For businesses and professionals, losing a well-known number can disrupt communication and lead to missed calls from clients, partners, or contacts.

Fortunately, phone number portability makes it possible to change operators while keeping the same number. This ensures continuity in your communications and avoids the need to inform all your contacts of a new phone number.

What number portability means

Number portability allows a phone number to be transferred from one operator to another without interruption of service. Once the transfer is completed, incoming calls continue to reach you exactly as before, even though the underlying service provider has changed.

This applies to many types of VoIP and IP telephony numbers, depending on local regulations and technical eligibility.

Why keeping your number is important

Your phone number is often a key part of your professional identity. It may appear on websites, business cards, invoices, or marketing materials.

Keeping the same number helps:

• Avoid losing calls from existing customers or partners
• Maintain trust and continuity in professional relationships
• Prevent administrative and communication disruptions

Portability as a regulated right

In many countries, number portability is a regulated right for IP telephony users. Operators and service providers are generally required to allow the transfer of eligible numbers when a customer decides to switch.

However, the exact conditions, required documents, and timelines may vary depending on the country and the type of number involved.

How portability services are accessed through a marketplace

As a marketplace, Hivoox does not perform number portability directly. Instead, it connects businesses and professionals with sellers offering VoIP services that support number portability.

The marketplace helps clarify whether a number is eligible, what documentation may be required, and how the portability process is typically handled, allowing users to compare solutions before committing to a new operator.

What to check before starting a number transfer

Before requesting portability, it is recommended to verify:

• The eligibility of your current phone number
• Any contractual obligations with your current operator
• The estimated transfer timeframe
• Whether service interruption is expected during the transition

Preparing these elements in advance helps ensure a smooth and successful transfer.
