How to Keep Your Phone Number When Switching Operators

Switching to a new mobile or landline provider is often the best way to save money or get better service. However, the thought of changing your phone number can be a major deterrent. Fortunately, the process of keeping your existing number—known as number portability—is simpler than most people realize.

In France, the telecommunications market is highly regulated to protect consumers. These regulations ensure that you can move from one operator to another without losing your identity or your contacts. Whether you are moving between major carriers or switching to a budget-friendly alternative, the steps remain largely the same.

This guide will walk you through the entire process, from obtaining your RIO code to understanding the legal timelines. By following these steps, you can enjoy a seamless transition to your new provider without the hassle of updating your number with every friend, family member, and bank account.

What is Number Portability?

Number portability, or “portabilité du numéro,” is a legal right that allows you to keep your current phone number when you change your service provider. This applies to both mobile phones and landlines. In the past, switching providers meant getting a brand-new number, which caused significant inconvenience for users.

Today, the process is automated and handled between the operators themselves. When you request portability, your new operator acts on your behalf to terminate your old contract and transfer the number to their network. This system is designed to promote competition and make it easier for consumers to find the best deals.

The Golden Rule: Do Not Cancel Your Contract

The most important piece of advice for anyone looking to keep their number is this: Do not cancel your current contract yourself. If you manually terminate your subscription with your old provider before the transfer is initiated, you risk losing your phone number forever.

When a line is canceled, the number eventually goes back into a pool of available numbers. Once it is disconnected, it becomes much harder, and sometimes impossible, to retrieve. Instead, you should let your new operator handle the cancellation as part of the porting process. This ensures that the line remains active until the very moment the transfer occurs.

Understanding the RIO Code

The key to the entire portability process is the RIO code (Relevé d’Identité Opérateur). This is a unique 12-character alphanumeric code assigned to every phone line in France. It serves as a digital fingerprint that identifies your specific line and your current operator.

The RIO code is composed of four distinct parts:

  • Operator Code: Two digits identifying your current provider.
  • Contract Type: A single letter (usually ‘P’ for individuals or ‘E’ for businesses).
  • Customer Account: Six characters representing your account number.
  • Security Code: Three characters generated by an algorithm to prevent errors.

How to Get Your RIO Code

Obtaining your RIO is remarkably easy and can be done in seconds. For mobile phones, simply dial 3179 from the line you wish to port. This is a toll-free, automated service available 24 hours a day, seven days a week.

Once you call, an automated voice will read out your RIO code and tell you if you are still under a commitment period with your current provider. Immediately after the call, you will receive an SMS containing the RIO code and your contract end date. This SMS is crucial, as you will need to provide the code to your new operator.

For landlines, the process is similar. You can often dial 3179 from your home phone. If you are unable to access the line, you can find the RIO on your monthly bill or by logging into your online customer portal.

The Step-by-Step Porting Process

Once you have your RIO code in hand, the rest of the process is straightforward. Here is how to navigate the transition step-by-step:

1. Choose Your New Plan

Research the market and select the new mobile or landline plan that fits your needs. Ensure that the new provider offers the coverage and features you require.

2. Provide Your Information

When signing up for the new service, you will be asked if you want to keep your current number. Select “Yes” and enter your current phone number and the 12-character RIO code exactly as it appeared in your SMS or bill.

3. Select a Porting Date

In many cases, you can choose a specific date for the transfer. If you don’t choose one, the operator will assign the earliest possible date, which is usually within 3 to 10 working days.

4. Receive Your New SIM Card

If you are switching mobile providers, your new operator will send you a new SIM card. Keep your old SIM card in your phone until the day of the transfer.

5. The Day of the Transfer

On the scheduled date, your old SIM card will stop working, and your new one will become active. You may experience a few hours of “service downtime” while the technical transfer takes place, but this is usually minimal.

Switching Landline Operators

Porting a landline number follows the same logic but has a few specific nuances. In France, landline numbers are often tied to geographic zones (starting with 01, 02, 03, 04, or 05). If you are moving to a different region, you may not be able to keep a geographic number.

However, numbers starting with 09 (non-geographic VOIP numbers) can be ported anywhere within the country. When switching internet service providers (ISPs), providing the landline RIO allows the new ISP to cancel your old internet subscription and phone service simultaneously.

Timelines and Costs

The legal minimum delay for porting a mobile number in France is three working days. However, most consumers opt for a slightly longer window to ensure they receive their new SIM card in the mail before the old service is cut off.

Is there a cost? For the consumer, the act of porting the number is free. Operators are not allowed to charge you specifically for the portability service. However, you should be aware of potential costs related to your old contract:

  • Commitment Periods: If you leave your old operator before your contract ends, you may owe early termination fees.
  • Final Bill: Your old operator will send a final invoice to cover the days used up until the porting date.
  • New SIM Fees: Your new operator may charge a small fee (usually around €10) for the physical SIM card.

Troubleshooting Common Issues

While the system is highly automated, occasional issues can arise. If your portability request is rejected, it is usually due to one of the following reasons:

  • Incorrect RIO: Double-check the 12 characters. A single typo will cause the request to fail.
  • Inactive Line: If you already canceled your old line, the RIO will no longer work.
  • Pending Orders: If there is already a change being processed on your account, the portability might be blocked.

If you encounter issues, contact the customer service department of your new operator. Since they want your business, they are highly motivated to help you resolve any technical hurdles with the transfer.

The Role of ARCEP

The entire portability framework is overseen by ARCEP (Autorité de régulation des communications électroniques, des postes et de la distribution de la presse). They set the rules that operators must follow, ensuring that the process remains fast, free, and fair for all consumers. If you ever feel an operator is unfairly blocking your right to port your number, you can report the issue to ARCEP through their official platform.

Conclusion

Keeping your phone number when switching operators is a right that simplifies your digital life. By obtaining your RIO code through 3179 and letting your new provider handle the heavy lifting, you can switch plans as often as you like to find the best value. Remember to keep your line active until the transfer is complete, and double-check your RIO for accuracy.
