Last Comments Northwestel never requests customer information over the Internet or via e-mail. Be cautious of emails pretending to represent Northwestel that ask you to provide personal and/or account information. Emails of this nature are scam attempts known as "phishing", designed to obtain personal and/or account information (name, username, password, etc.). Some of these requests look extremely professional and can come from a major bank, university, or local business If you would like to report the attempted scam, please forward the original message to: phishing@northwestel.net 1/1/2019 Confidential
