What PortingXS does

PortingXS (legal entity: PXS B.V.) is a Dutch private company founded in 2001 and headquartered in Rotterdam, with additional operating presence in The Hague. It provides modular telecom numbering services to two primary customer segments: telecommunications operators and government telecom regulators. The company has built a five-product portfolio covering the full numbering lifecycle: a Number Portability Clearinghouse that coordinates mobile and fixed line porting between operators, a Number Portability Gateway that integrates operator networks with central portability systems, a Number Management System for assigning and managing numbering resources, a Number Information Register that maintains national SIM, subscriber, and device details, and an Operator Switching Hub that facilitates end-consumer service switching such as internet provider changes. The platform connects 250 operators across 40 countries, handles approximately 500,000 transactions per hour, and serves 5,000 active users.

The underlying technology is a modular platform architecture rather than a single product, designed to allow operators and regulators to adopt individual components while supporting integration with operator BSS/OSS and national regulatory infrastructure. The company holds ISO 27001 information security certification, which is positioned as a procurement-grade requirement for regulated telecom and government buyers. Implementation follows a four-step process (challenge identification, implementation, onboarding, go-live) that the company emphasizes is tailored to each customer's regulatory and market context.

PXS sells through an enterprise field-sales motion with consultative demos and bespoke onboarding; pricing is not publicly disclosed and is described as tailored per engagement. Revenue is generated through recurring B2B subscriptions and managed-services contracts with telecom operators and national regulators. The company is privately held with no disclosed funding rounds, parent company, or ownership structure, and headcount is reported at 11-50 employees. Recent strategic activity has centered on geographic expansion into the Caribbean and South America (Guyana in 2020, Sint Maarten in 2023) and brand investment through MWC Barcelona 2026 participation tied to the firm's 25th anniversary.

Broad incumbents

• Huawei: Offers Number Portability solutions via its Carrier Network Business Group, with strong presence in Asia, MENA, and parts of Africa where it competes directly for national clearinghouse mandates.
• Sinch: Global CPaaS incumbent with messaging, voice, and number management capabilities; competes with PXS more loosely through enterprise-focused numbering and routing products.
• Nokia: Provides numbering and network-layer number portability products within its broader mobile networks portfolio; competes with PXS for large operator RFPs but as part of an end-to-end telecom stack.
• Ericsson: Global telecom equipment and OSS vendor offering Number Portability Clearinghouse and gateway solutions as part of a much broader BSS/OSS portfolio serving Tier-1 operators.

Others

• Bandwidth Inc. Manages large inventories of phone numbers/DIDs and offers number management APIs to enterprises and CPaaS platforms; adjacent rather than directly competitive with PXS's operator/regulator focus.

Direct peers

• Somos: Administrator of the U.S. Number Portability Administration Center (NPAC) and pooling administration; a primary U.S. counterpart providing managed services for number portability and routing at national scale.
• iconectiv: U.S.-based authoritative numbering services provider (formerly Telcordia/Bellcore). Operates the LERG routing guide and various number administration functions; directly comparable as an independent specialist serving telecom operators and regulators with numbering infrastructure.
• Mobileum: Analytics-driven telecom services vendor covering number portability, roaming, and fraud; overlaps with PXS in providing number portability and subscriber data solutions to mobile operators.
• NetNumber: Provider of centralized number information, routing, and signaling services via its Titan platform; comparable as an independent specialist delivering numbering infrastructure to operators globally.
• Neustar (TransUnion): Historically the U.S. NPAC administrator and operator of key numbering databases; now part of TransUnion, but still a directly comparable peer in numbering administration services.
