Alias Number

Network-level number masking that protects users’ phone numbers without adding friction.

Every time your app forces a user to share a real phone number with a stranger—delivery driver, marketplace buyer, field technician—you introduce privacy risk and trust erosion. Alias Numbers lets you provision temporary phone number aliases and create mirrored routes between parties, so calls and SMS can flow while real numbers stay hidden. Users keep the experience they expect: a normal phone call from the native dialer.

Mask phone numbers, not the user experience

Alias Numbers is built for digital platforms and service operations where people must connect quickly in the real world without permanently exchanging personal numbers. Your platform generates an alias with a configurable lifespan and manages call/SMS routing through mirrored routes. The result is privacy-by-design and better control over communications, while keeping phone calls as simple as dialing a standard number.

Proof / market signal paragraph
User demand is already clear: 59% of people feel uncomfortable sharing their phone number, and 89% say they would pay extra to keep it protected. In privacy-sensitive flows, number masking is no longer a “nice-to-have, it’s a retention and trust lever.

Multi-carrier coverage in France, designed to scale internationally

A masking feature only works if it works everywhere your users are. Alias Numbers is available today on Orange Developer with multi-operator reach in France, enabling communication across Orange, SFR, Bouygues Telecom, and Free.

Roadmap: CEE + UK coverage planned for October 2026, enabling cross-border scalability via a single integration point.

Benefits

Real number masking

Protect users by masking real numbers with one-way or two-way number masking, depending on your policy and flow.

Business-ready numbers

Provision a unique or context-based alias (per job, per delivery, per conversation) so routing matches your operational model.

Smart callbacks

Control what happens when someone calls back (e.g., customer → employee → support) during and after the service window.

Contact, Know your customer product icon

Frictionless UX

No extra apps, no second SIMs, no manual switching—users call from the native dialer and reachability stays high.

Use cases

Alias Numbers is ideal when two parties need to connect quickly but should not keep each other’s personal numbers afterward.

Last-mile delivery

Let couriers contact recipients on delivery day without exposing either party’s real number. Reduce failed deliveries and “can’t reach customer” incidents.

Field Service Management (technicians)

Enable technician ↔ customer coordination during the service window, then expire the alias automatically once the job is closed.

Classifieds & peer-to-peer marketplaces

Protect buyers and sellers during negotiation and handoff. Reduce unsolicited follow-ups and improve trust in the platform.

Dating platforms

Allow members to speak by phone without disclosing personal numbers until they choose to share them.

Mobility (taxi / ride-hailing)

Mask numbers in driver ↔ passenger calls to avoid recontact after the ride and improve platform safety perception.

Case study

Nomadia: improving last-mile coordination while protecting phone numbers

In last-mile delivery, phone calls are often the difference between a completed drop-off and a failed attempt—yet sharing personal numbers creates avoidable privacy risk. With Alias Numbers, Nomadia provisions temporary aliases for each delivery interaction, enabling courier ↔ recipient communication while keeping real numbers private. The result is smoother operations and a stronger trust signal for end users.

Frequently-Asked Questions

Alias Numbers is a network-level number masking API that lets your platform provision temporary phone number aliases and route calls/SMS between two parties without revealing their real numbers.

Both. You can mask one participant’s number or both participants’ numbers, depending on your compliance and privacy requirements.

No. The experience is designed to be zero-friction: users call a normal-looking number from the native dialer, while the platform manages aliasing and routing.

It depends on the operational flow. Typical guidance: 1 day (last-mile delivery), 1 week (field service visits), 1 month (classifieds / P2P negotiations). The goal is to match the service window and expire afterward.

You can configure smart callback rules—for example, route callbacks to support, play an informational message, or block after expiration, depending on your policy.

Yes in France: the API is positioned with multi-operator reach across Orange, SFR, Bouygues Telecom, and Free, which is critical for platform-scale usability.
