Every time your application forces a user to share their real phone number with a stranger, be it a delivery driver, a marketplace seller, or a field technician, you risk losing their trust. With 59% of users uncomfortable sharing their mobile numbers, user privacy is no longer just a compliance checkbox; it is a critical retention metric. Here is how network-level number masking bridges the gap between operational efficiency and customer trust.

The friction behind the digits: The cost of exposed identities

In the digital platform economy, the phone number is a universal identifier. It is how we confirm transactions, coordinate deliveries, and verify accounts. However, forcing users to reveal this personal data to third parties during real-world interactions creates a massive friction point.

Data leaks and unsolicited follow-ups damage user retention and brand reputation. The market demand for privacy is clear:

• 59% of consumers state they are not comfortable sharing their personal phone numbers to complete transactions.
• 89% of users are willing to pay an extra fee to guarantee their phone number remains protected.

For Product Managers and CTOs, ignoring these numbers means leaving a substantial portion of your addressable market exposed to churn.

Introducing the Alias Numbers API: Network-level privacy without compromise

To solve this dilemma, platforms have traditionally relied on rudimentary workarounds. However, legacy approaches force users into a bad trade-off between privacy, reachability, and simplicity.

The Alias Numbers API, available on the Orange Developer portal, handles number masking directly at the network layer. Instead of exposing a user’s real MSISDN, the API provisions a temporary alias with a configurable lifespan suited to your specific operational flow:

Reachability vs. hidden numbers

When users hide their caller ID (anonymous calls), pick-up rates plummet. Consumers routinely ignore hidden numbers to avoid spam. The Alias Numbers API ensures 100% reachability by displaying a legitimate, localized mobile number on the screen. The call or SMS goes through perfectly, but the real identity remains completely masked.

Simplicity vs. secondary SIMs and virtual number apps

Alternative consumer workarounds like secondary SIM cards or over-the-top (OTT) virtual number applications (such as Onoff) require complex setups, manual switching, and extra monthly subscriptions. The Alias Numbers API delivers a zero-friction experience. Users do not need to download a second app, configure a dual-SIM device, or manage a new number. The platform automates everything via software, routing the communication seamlessly through their existing mobile line.

Use case	Recommended alias duration	Operational goal
Last-mile delivery	1 Day	Allow the courier to locate the customer on delivery day only.
Field service management	1 Week	Enable coordination between the technician and the homeowner during the service window.
Classified ads & Peer-to-peer	1 Month	Protect buyers and sellers during negotiations until the transaction closes.

High intent, immediate adoption

The market appetite for this solution is already proven. In France, the intent to use temporary numbers is highly pronounced:

• 17% of users would certainly use the service.
• 31% of users would probably use it.
• 32% of users could potentially adopt it.

This represents an aggregate 80% positive market intent, offering platforms a strong competitive differentiator.

Technical roadmap: True cross-carrier reach

A communication API is only as good as its reach. Building a privacy feature that only works when both parties are on the same network is functionally useless for a growing digital platform.

• Current availability: The Alias Numbers API is fully available via the Orange Developer portal. It features complete multi-operator coverage in France, meaning seamless routing across Orange, SFR, Bouygues Telecom, and Free networks.
• October 2026 expansion: The roadmap introduces a single integration point to access unified CEE (Central and Eastern Europe) + UK coverage, scaling your user protection across international borders without rewriting your integration backend.

Next steps: Secure your communication flow

Stop making your users choose between convenience and privacy. Implement temporary number masking to eliminate friction in your transactional workflows.
