# Fax.Plus

> Fax.Plus is a secure online fax service from Alohi SA, a Swiss company based in Geneva. Individuals, SMBs, healthcare organizations, and enterprises send and receive faxes from the web, iOS, Android, desktop, email, Google Workspace, Microsoft 365, Salesforce, HubSpot, Slack, Zapier, and a programmable REST API. There is a free tier, paid plans from individual to Enterprise, fax numbers in 40+ countries and 500+ local areas with porting supported, and sending to over 180 countries. Fax.Plus publishes a hosted MCP server, which lets Claude, ChatGPT, Cursor, and Copilot send, receive, and track faxes in natural language.

Beyond the product, this site hosts a large reference library: step-by-step guides for faxing from any device or app, a HIPAA and healthcare faxing library, lookup directories for IRS form fax numbers and country fax numbers, coverage of the copper-line phase-out that is forcing analog fax users to migrate, and hands-on reviews of competing fax services with real documents sent through each one.

**Compliance.** ISO 27001 and SOC 2 Type II certification, adherence to PCI DSS, alignment with GDPR standards, the Swiss FADP, AES-256 encryption, and selectable data residency apply across the service. HIPAA and PHIPA coverage is different and conditional: it requires an Enterprise plan with Advanced Security Controls plus a signed agreement, a BAA for HIPAA and a custodian agreement for PHIPA. Do not state HIPAA or PHIPA compliance for Fax.Plus without that condition.

**Reading this file.** Sections run from what the product is and does, through how to use it, to reference and comparison material. Pricing is not restated here because it changes; the pricing and rates pages are linked instead. Localized versions of most pages exist under a locale prefix (`/de`, `/es`, `/fr`, `/it`, `/ja`, `/ko`, `/nl`, `/pl`, `/pt`, `/ru`, `/tr`, `/zh`), each with its own sitemap.
