Bring your existing fax number

Free port-in. Port-out costs $10 per number, or $150 for vanity numbers, paid upfront and refunded if the transfer fails.

Free port-in for eligible US/Canada local numbers on Standard or Business, monthly or annual, including HIPAA Secure. Lifetime and 30-day plans do not accept port-ins.

Porting details and eligibility

Port-in is limited to eligible US/Canada local numbers on Standard or Business monthly/annual plans, including HIPAA Secure. New subscription billing begins after carrier completion and verified fax routing; existing subscriptions keep their billing and page usage. Vanity means North American area code 800 or four identical trailing digits. All port-outs are prepaid. Confirmed failure or cancellation receives a full refund of the transfer fee. Delays and correctable exceptions do not trigger refunds. Successful port-out ends number service and subscription renewal without a prorated subscription refund. Outstanding usage remains payable. A canceled subscription may still port out while its number remains assigned. Pending transfers prevent number release.

SingleFax Terms of Service

Last updated:

All the terms that you agree to when you sign up for a Monocube LLC product.

Company Definition

When we say "Company", "we", "our", or "us" in this document, we are referring to Monocube LLC.

Services Definition

When we say "Services", we mean our websites, including monocube.com, singlefax.com and others and any product created and maintained by Monocube LLC. That includes Monocube apps, whether delivered within a web browser, desktop application, mobile application, or another format.

User Definition

When we say "You" or "your", we are referring to the people or organizations that own an account with one or more of our Services.

Important Notice

We may update these Terms of Service ("Terms") in the future. Typically these changes have been to clarify some of these terms by linking to an expanded related policy. Whenever we make a significant change to our policies, we will refresh the date at the top of this page and take any other appropriate steps to notify account holders.

When you use our Services, now or in the future, you are agreeing to the latest Terms. There may be times where we do not exercise or enforce a right or provision of the Terms; however, that does not mean we are waiving that right or provision. These Terms do contain a limitation of our liability.

If you violate any of the Terms, we may terminate your account. That's a broad statement and it means you need to place a lot of trust in us. We do our best to deserve that trust by being open about who we are, how we work, and keeping an open door to your feedback.

Personal records, Enhanced Privacy, and HIPAA Secure

Individuals sending their own health records, or acting as an authorized personal representative, may use standard send without a HIPAA BAA. Enhanced Privacy is an optional paid upgrade: $6.50 for 1–10 billable pages or $10 for 11–100, plus any destination adjustment shown in the quote. It uses shorter document retention, privacy-safe notifications, and securely stored transmission receipts. A personal upgrade does not execute a BAA, make you a HIPAA covered entity, or bind the receiving clinic.

If you send patient information on behalf of a HIPAA covered provider or business associate, including as a sole proprietor, you must choose HIPAA Secure and have an authorized signer accept the BAA before uploading. The role you act in determines this requirement, not your account label or an automated document classification. Personal Enhanced Privacy does not substitute for the healthcare BAA.

For standard website uploads, we may extract text and use automated classification to show an advisory reminder that a document may contain health information. The check can miss or misclassify documents. It does not determine your legal role, automatically enable a premium option, change your price, or certify compliance. The hint stores a classification result rather than a retained OCR transcript. Secure sends skip this advisory classification. Any processing completed before you choose an upgrade remains subject to the policy that applied at that time; a later BAA does not retroactively cover earlier processing.

Neither option promises end-to-end encrypted fax transmission, delivery to the intended person, or control of the recipient’s handling of the fax. Verify the destination and your authority to send the document. Standard uploads also have transport and storage safeguards; the upgrade is not a claim that standard sending is unencrypted.

For receiving numbers and intake services operated for a covered provider, the BAA is with that provider for the service we supply on its behalf. It does not automatically cover a separate sending service for another provider. The BAA controls if these Terms conflict with it concerning PHI. Do not send regulated PHI through MCP, MPP, public REST API, email-to-fax, or the Chrome extension.
