Coverage

mintfax sends faxes to landline destinations across North America, Europe, and Asia-Pacific. You submit the recipient’s fax number and a document through the API. You do not need a dedicated fax number or fax hardware.

Format the recipient’s number

Include a leading +, the country code, and the remaining digits. Leave out spaces, hyphens, and parentheses.

The international sending guide explains country-specific number formatting and destination support.

The recipient must have a working fax service. A number that reaches voicemail, a mobile handset, or a service without fax support cannot receive your document.

Every supported destination uses the same per-page rate, with no international surcharge.

A different country, the same API

Use the same API and signed webhooks for domestic and international faxes. If delivery fails, the fax record includes an error code so you can decide what to do next.

mintfax retries temporary failures such as a busy line. It stops immediately for errors such as an invalid number. The default is three attempts; you can set between one and five for each fax.

See the error guide for causes and next steps, and pricing for per-page rates.

Sending and receiving

mintfax sends faxes only. It does not provide receiving numbers, receive faxes, or port existing numbers.
