What Quackr.io does
Quackr.io operates a cloud-based virtual phone number platform that lets users receive SMS online through disposable or rented numbers, avoiding the exposure of personal phone numbers during online sign-ups and verification. The product surface spans free shared VoIP numbers (no registration, ad-supported, available in 24+ countries) and premium dedicated non-VoIP numbers (15+ countries, rented from 1 week to 12 months) that work on platforms that block VoIP — including WhatsApp, Telegram, PayPal, Instagram, and Signal. Underlying infrastructure supports an 8-second average SMS delivery speed and provisions numbers in under 3 seconds.
The company is incorporated in Hong Kong as Quackr Limited, with reported operating presence in London. It serves four distinct customer segments: privacy-conscious individual consumers, digital marketers and agencies needing multiple isolated identities, developers and QA teams requiring programmatic SMS verification, and enterprise/wholesale buyers with bulk volume needs. Distribution is product-led via web, iOS, and Android apps, augmented by a dedicated enterprise sales motion and a developer-facing REST API plus MCP Server for AI agents.
Revenue is generated primarily through subscription-based rental fees (e.g., US numbers from $12.99/week to $99.99/12 months, UK numbers from $14.99/week to $39.99/12 months), advertising on the free tier, and custom-priced enterprise bulk contracts with up to 80–85% volume discounts. The team is small (1–10 employees), no external funding has been disclosed, and recent product launches (MCP Server, Carrier Lookup, VPN, eSIM, Quackr ID) signal an expanding product surface around disposable digital identity rather than SMS verification alone.

Quackr.io competitors and assessment
Company assessmentDirect peers
- Hushed: Hushed provides temporary and disposable phone numbers for SMS and calls across multiple countries, with a freemium and subscription model targeting the same privacy-conscious and multi-identity use cases as Quackr.
- Burner: Burner offers short-lived second phone numbers for SMS, calls and apps, positioned around privacy, dating and online verification — overlapping directly with Quackr's core rental product.
- TextNow: TextNow is a large ad-supported VoIP provider offering free and paid phone numbers for SMS and calls in the US and Canada, competing head-on with Quackr's free VoIP tier and consumer rentals.
- Dingtone: Dingtone provides free and low-cost second phone numbers for SMS verification and international calling, with a similar freemium-plus-credit model targeting users who want a disposable identity.
- 2ndLine: 2ndLine offers a second US phone number for SMS, calls and verification, directly competing with Quackr in the use case of bypassing personal-number exposure for online sign-ups.
- NumberBarn: NumberBarn sells short-term rental and disposable US numbers for SMS verification, closely mirroring Quackr's premium non-VoIP rental product for individuals and small businesses.
- Telos: Telos provides virtual and temporary phone numbers for SMS verification and enterprise messaging, serving both consumer privacy users and businesses needing bulk verification capacity.
Broad incumbents
- Twilio: Twilio is a large CPaaS incumbent whose telephony APIs power number provisioning, SMS and verification at scale; while not a consumer disposable-number brand, it underpins much of the same infrastructure Quackr uses and is a likely long-term competitor in the AI agent verification space.
- Vonage: Vonage (Ericsson) offers cloud communications, virtual numbers and SMS APIs for enterprises; it competes with Quackr indirectly as a one-stop alternative for businesses needing programmable phone numbers.
Emerging players
- Proton: Proton bundles privacy services (mail, VPN, password manager, calendar) and has been expanding into eSIM and identity; its trajectory toward integrated privacy identity closely parallels Quackr's Quackr ID roadmap and represents a credible adjacent competitor.
