Global coverage with a practical focus on Canada and South Korea
Our platform specializes in practical deployments that align with business goals. For teams targeting Canadian users, you can obtain anumber for canadato strengthen local trust, improve deliverability, and support compliant customer communications. In markets like South Korea, where regulatory expectations around messaging are strict, a local presence helps ensure higher acceptance rates and better engagement with Korean mobile carriers.
Beyond these two markets, the system is designed to scale to additional jurisdictions, enabling you to respond quickly to demand in new regions. By maintaining a centralized pool of numbers across countries, your marketing and product teams can configure regional campaigns without involving separate vendors for each geography.
Format: Applied Solution — how we structure the delivery
The format we follow is an applied solution approach. This means we describe concrete steps, architectural components, and operational patterns that you can implement within your organization today. The aim is not theoretical capabilities but a repeatable workflow that yields measurable outcomes: faster time-to-value, improved deliverability, and clearer visibility into every SMS interaction.
Technical overview: how the service works under the hood
The platform is built around a modular, cloud-native architecture designed for reliability and scale. Here are the essential components and how they interact:
- Number inventory service:maintains an up-to-date catalog of virtual numbers by country, type (local, mobile, toll-free), and carrier capabilities. It supports budget-aware provisioning and automated reclamation of unused numbers.
- Provisioning and activation:when a client selects a country and number type, the provisioning service reserves the DID (direct inward dial) or short code as appropriate and activates it for sending and receiving messages.
- Messaging gateway:routes inbound and outbound SMS through carrier-grade routes, with intelligent failover, message concatenation for long messages, and per-number throughput controls.
- API layer:a clean RESTful interface for developers to search, provision, configure, and manage numbers, as well as send messages and check status.
- Delivery analytics:real-time dashboards and historical reports on throughput, success rates, carrier performance, and latencies by country and number.
- Security and compliance:TLS for all API calls, encryption at rest for message content, access controls via OAuth or API keys, and optional data residency settings to comply with regional laws.
How to set up: a practical integration flow
The following steps outline a pragmatic integration path you can implement in weeks, not months:
- Define the use cases:identify where negative consequences would occur if verifications fail or messages are delayed. Typical use cases include user onboarding, account recovery, and promotional updates.
- Choose countries and number types:decide which jurisdictions matter for your audience. For example, a Canadian onboarding campaign benefits from anumber for canada, while regional campaigns in Asia may require a South Korea local number to maximize deliverability.
- Set up API access:obtain API keys, configure sandbox or staging environments, and define routing rules for different campaigns or brands.
- Provision numbers:use the provisioning API to search and acquire numbers. Attach metadata to each number to simplify management (brand, campaign, geo-context).
- Integrate messaging workflows:implement endpoints to send SMS, receive inbound replies, and process status callbacks. Build verification flows that deliver codes instantly and handle retries gracefully.
- Monitor and optimize:review dashboards, adjust throughput per country, and refine routing policies to improve deliverability and cost efficiency.
API and integration details: practical endpoints you can rely on
The following are representative RESTful endpoints you will encounter when implementing this applied solution. They are designed to be intuitive for developers and compatible with modern automation tooling. For production deployments, consult the official docs for exact parameters, rate limits, and security guidance.
- GET /v1/numbers/search — discover available numbers by country, type, and capacity.
- POST /v1/numbers/provision — reserve and activate a number or pool of numbers for a customer or campaign.
- POST /v1/messages/send — deliver an outbound SMS using a specific number as the sender.
- GET /v1/messages/status — retrieve delivery status, including accepted, delivered, failed, and queued events.
- POST /v1/webhook — configure callback URLs for inbound messages and status updates.
These endpoints are designed to be integrated into existing CRM, marketing automation, or identity verification pipelines. By combining number provisioning with a robust messaging gateway, you can ensure consistent delivery across geographies, even when users are roaming or using local carriers with different policies.
Security, compliance, and data governance
Security and privacy are foundational to any business SMS operation. The platform employs end-to-end considerations across the lifecycle of a message:
- Data in transit:TLS 1.2+ for all API interactions and webhook callbacks.
- Data at rest:encryption of message bodies, metadata, and logs in compliant storage systems.
- Access control:role-based access, API keys with granular scopes, and IP allowlists per client.
- Regulatory alignment:configurable data residency options, consent management, and regional policy awareness to support GDPR, CCPA, PIPEDA, and other frameworks as applicable.
- Monitoring and incident response:continuous anomaly detection, alerting, and post-incident reviews to minimize risk and downtime.
Use cases: practical business scenarios for virtual numbers
Business clients use virtual numbers to support a range of activities that benefit from local presence and reliable messaging workflows. Below are concrete scenarios where our applied solution shines:
- User onboarding and verification:verify new accounts by sending one-time codes to a country-specific number, reducing fraud and increasing signup completion.
- Two-factor authentication (2FA):timely codes delivered by SMS to ensure secure access controls with a failover strategy if one route is congested.
- Marketing and transactional campaigns:send promotional messages, order confirmations, and alerts with appropriate regional headers and compliance controls.
- Marketplace communications:support sellers and buyers with local vote or verification codes, including cross-border interactions.
- Platform integrations:partner channels and advertisers, including platforms likedoublelist, can leverage regional numbers to improve trust and verification flows.
Why this solution works for business teams
For business teams, the value lies in simplicity, control, and measurable outcomes. A centralized platform for virtual numbers reduces vendor fragmentation, speeds up time-to-market for new campaigns, and provides visibility into performance at the campaign, country, and carrier levels. The ability to scope numbers by country, choose local or toll-free variants, and monitor via a single API portal creates operational savings and a better user experience for customers and partners alike.
Pricing and planning: practical guidance
Pricing models typically combine monthly rental for local numbers with per-message charges. The applied solution supports flexible plans, including pay-as-you-go and tiered packages that reflect expected volumes by country. For businesses starting with Canada or South Korea, you can pilot with a small set of numbers and scale as your verification volumes grow. Transparent dashboards help you correlate spend with throughput and success rates, so you can optimize campaigns without surprises.
