Terms of Service

This is a translation for reference. If it differs from the Mongolian text, the Mongolian text prevails.

Version 1.0. Effective 1 November 2026.

These terms apply to anyone (the "User") who verifies a phone number through the 2fa.mn service of Hi Commerce LLC (the "Company"), and to visitors of https://2fa.mn. By sending a verification message to 150073, the User accepts these terms.

1.1. The service

1. 2fa.mn verifies that a phone number belongs to the User when the User sends a message (MO SMS) from their own phone to special number 150073.
2. The Company passes the result to the company that owns the app or website the User is using (the "Customer").
3. The Company will never ask for the User's passwords, bank details or ID card details.

1.2. Price and payment

1. Each message sent to 150073 costs 150₮ (VAT included). The User's mobile operator charges it, either on the monthly bill (postpaid) or from the balance (prepaid).
2. Before the User sends a message, the Customer must clearly show the price, the number and the message text.
3. A charge arises only from a message the User sends themselves. The Company never charges the User without consent or signs them up to any subscription.
4. The Company does not charge the User for reply messages (MT SMS) it sends.
5. If a technical error causes a double or wrong charge, the Company checks it with the operator after receiving the complaint and refunds it.

1.3. User obligations

1. Verify only phone numbers you own or are entitled to use.
2. Do not use the service to register with another person's number, for fraud, or for any illegal purpose.
3. You may decline to verify at any time. No message means no charge.

1.4. Limitation of liability

1. The Customer is responsible for its own app, website, goods, services and content.
2. The Company is not liable if a message fails or is delayed because of a mobile network outage or force majeure. Any wrong charge in that case is handled under clause 1.2.5.
3. The Company aims to keep the service running without interruption but does not guarantee it will be free of maintenance or unexpected outages.

1.5. Personal data

The User's data is processed under the Privacy Policy.

1.6. Changes

The Company will publish any change to these terms on https://2fa.mn 30 days in advance. Using the service after a change takes effect means accepting the updated terms.
