Telnum

What Telnum does

Telnum is a private virtual phone number and VoIP service provider operating since 2011, delivering direct-inward-dial (DID) numbers, SMS-enabled numbers, Non-VoIP real-SIM numbers, toll-free numbers, disposable verification numbers, IVR, multichannel numbers, virtual office, call forwarding, wholesale DID, and SMS forwarding to a horizontal mix of small businesses, large corporations, call centers, remote/virtual-office operators, frequent travelers, and privacy-conscious individuals across more than 90 countries and 6,500 cities.

The underlying platform combines SIP-based VoIP infrastructure with physical-SIM-backed mobile number inventory from carriers. This dual capability is the core technical differentiator: VoIP numbers deliver low-cost, instantly activatable local presence, while Non-VoIP real-SIM numbers are accepted by strict verification platforms such as Google, WhatsApp, and Amazon that block internet-based numbers. Supporting features include free SIP and Telegram/Slack forwarding, multichannel DIDs handling up to 30 simultaneous calls, IVR trees with recordings in 19+ languages, and webhook-based SMS routing to email, mobile, Telegram, Slack, and HTTP endpoints.

Telnum monetizes primarily through recurring monthly subscriptions (voice numbers $10-$150/month by country, SMS numbers, Non-VoIP numbers, toll-free numbers, and a $65/month virtual office bundle), with one-time unit pricing starting at $1 for disposable verification numbers and usage-based per-minute charges for outbound call forwarding. The go-to-market is self-serve, PLG-driven via telnum.net and lk.telnum.net, with payment via bank cards, PayPal, and cryptocurrency (Bitcoin, USDT), and a wholesale DID channel serving resellers with bulk inventory and dedicated account management. The company is privately held, founder/internally financed with no disclosed funding rounds, headquarters jurisdiction unspecified, and no public leadership team disclosed in the source data.

Direct peers

• Plivo: Plivo is a CPaaS provider offering global virtual numbers, voice, SMS, and SIP services with API-first delivery, competing directly with Telnum's SIP-forwarding and SMS-forwarding use cases for SMBs and developers.
• Sonetel: Sonetel provides virtual phone numbers and a cloud-based business phone system (IVR, call forwarding, virtual office) targeted at SMBs and international entrepreneurs — closely overlapping Telnum's SMB and virtual-office segments.
• DIDWW: DIDWW is a direct peer offering global DID numbers and VoIP services across 80+ countries with API access, competing head-to-head with Telnum in the SMB and reseller market for virtual local, mobile, and toll-free numbers.
• NumberBarn: NumberBarn sells and rents virtual local and toll-free numbers to SMBs and individuals with self-serve purchasing — a direct SMB-focused peer to Telnum's core DID rental and disposable number business.

Broad incumbents

• Twilio: Twilio is the dominant CPaaS incumbent offering programmable voice, SMS, and global numbers via REST APIs. It overlaps with Telnum in DID provisioning and SMS forwarding but targets developer/enterprise customers rather than self-serve SMBs and disposable verification.
• Vonage (Ericsson): Vonage offers unified communications, virtual numbers, and CPaaS APIs as part of a broad portfolio post-Ericsson acquisition. It overlaps with Telnum in SMB virtual office, IVR, and international number provisioning, but typically serves larger enterprise customers.
• Bandwidth: Bandwidth is a major CPaaS and carrier-of-record offering global DID numbers, messaging APIs, and 911/STIR-SHAKEN compliant voice services. It competes with Telnum at the carrier-of-record and wholesale DID layer with broader regulatory coverage.
• Telnyx: Telnyx is a CPaaS/ITSP offering global DID numbers, SIP trunking, voice and messaging APIs with developer-grade tooling. It competes with Telnum across SIP forwarding, voice numbering, and increasingly Non-VoIP messaging, but at greater scale and with richer APIs.

Emerging players

• Hushed: Hushed provides disposable and secondary phone numbers via mobile apps for privacy and verification use cases, directly competing with Telnum's disposable SMS and SMS-for-registration lines but focused on consumer/mobile-first delivery.
• TextNow: TextNow provides free and low-cost virtual phone numbers with mobile apps, overlapping with Telnum's traveler, privacy, and disposable verification segments but targeting consumer/freemium rather than SMB business customers.
