Customer Proprietary Network Information (CPNI) Policy

Triangle Communications and the Federal Communications Commission (FCC) are very concerned about protecting our subscribers' privacy and identity. The FCC enacted rules regarding Customer Proprietary Information (CPNI) effective December 7, 2007. These rules protect our subscribers. Triangle is not able to release any call detail or account information unless the security password is provided.

How does CPNI affect me? The CPNI rules affect subscribers calling in or visiting Triangle’s Havre office to inquire about subscribed features, average usage and long distance call information. Please be aware of the following when making inquiries on your account:

In person: You must provide a current, valid, government-issued photo identification or your CPNI Password before Triangle can disclose any information.

Via the phone: You must provide your CPNI Subscriber Password.

If members are unable to provide the password or ID, Triangle is forbidden from disclosing proprietary information.

What if I forget or lose my Subscriber Password? If subscribers are unable to provide the required password, Triangle can place a call to the phone number associated with the account or we can mail a letter to the address associated with the account to disclose the information.

Can I change my password? Subscribers can change their 5 to 13 digit CPNI Subscriber Password by calling Triangle’s office toll free at 611 from their home phone or completing the Authorized Account Representative (AAR) Form found at the bottom of this page. CPNI Subscriber Passwords must be 5 - 13 characters and not based on readily-available biographical information (telephone or social security number, mother's maiden name, address or date of birth). Triangle will notify account holders via U.S. mail, electronic mail or voice message when a CPNI Subscriber Password or Mailing Address is changed.

Can I authorize someone to have access to my account? To authorize another individual to have access to a member’s account, the AAR Form must be completed and mailed to Triangle at PO Box 1140, Havre, MT 59501. Once the form is received and the information is entered into our billing records, members’ Authorized Account Representatives will be allowed to inquire about and make changes to their account when they provide the required password or photo identification. This authorization does not change responsibility for your account or capital credits.

Triangle Telephone Cooperative Association, doing business as Triangle Communications respects your privacy and observes the privacy rules established by the Federal Communications Commission (FCC) and the Montana Public Service Commission.  Under federal law, you have the right to confidentiality of information regarding the telecommunications services to which you subscribe and Triangle Communications (Triangle) has the duty to protect that confidentiality.  This confidential information includes such things as specific telecommunications services you purchase, the number of services purchased, who your provider is for a service, call detail records and charges related to services purchased.  This information is referred to as Customer Proprietary Network Information (CPNI).

Triangle does not sell your account information or provide details of your telephone calls to other parties, unless required by law enforcement.  Triangle is authorized by the FCC to market, without approval, services to our customers within the categories of telecommunications service to which those customers subscribe.  Specifically, those services are local and long distance telephone service.  Triangle provides long distance telephone services through its subsidiary, Triangle Communication System, Incorporated.  From time to time we may market additional features to customers who subscribe to one or more of the service categories and do so through our subsidiaries.

Federal regulations require that telecommunications customers be given the opportunity to decline if the provider plans to use CPNI to market communications-related services outside of those to which customers subscribe.  Communications-related services include Internet in addition to local and long distance.  Declining to receive these offers will not affect any of your current services.  If you decide to opt-out of having your CPNI accessed or used for marketing communications-related services outside of those to which you subscribe, please let us know within 30 days by e-mail:

Send an e-mail message to This email address is being protected from spambots. You need JavaScript enabled to view it.; we will need your name, telephone number(s), and the effective opt-out date.  This information will be kept on file and your CPNI will not be used for marketing any communications-related services outside of those to which you subscribe unless you expressly revoke your opt-out notification by the method listed above.  Please be aware that if we don’t hear from you after 30 days has passed, we will presume that you have not opted-out but know that you can notify us at any time if you change your mind. 

If you have any questions or would like additional information regarding our use of CPNI, please contact Triangle Communications at 1-800-332-1201.
