Privacy Statement

Last updated: 6.11.2019 

We Respect Your Privacy.

Ameren Corporation (“Ameren”), its subsidiaries, including Union Electric Company d/b/a Ameren Missouri (“Ameren Missouri”), Ameren Illinois Company (“Ameren Illinois”), Ameren Transmission Company of Illinois (“ATXI”), and Ameren Services Company (“Ameren Services”) (hereinafter referred to collectively as “Ameren Companies”), are strongly committed to protecting the privacy of our customers, our shareholders, our employees, our retirees, and the users of our websites and mobile applications (each, our “Site”) as well as our products and services (hereinafter referred to collectively as “Services”). In light of this commitment, we adhere to the practices described in this Privacy Policy.

Please read this Privacy Policy carefully. By using our Site, you agree to our collection, use, and sharing of your personal information as described in this Privacy Policy. Please be aware that we follow this Privacy Policy in accordance with the applicable law as specified in the Terms and Conditions. In some cases, we may provide additional data privacy notices specific to certain products or services, practices, or regions. Those additional data privacy notices are to be read in conjunction with this Privacy Policy.

From time to time, we may change this Privacy Policy and will make reasonable efforts to publish such changes. Any changes will be immediately effective upon the posting of the updated Privacy Policy. Your continued use of our Site represents your consent to the terms of the new Privacy Policy. Please regularly check this Privacy Policy for any such updates.

Through your use of our Site and Services, we may collect Personal Information or Anonymous Information:  

  • Personal Information is information or a combination of information that identifies or relates to an identified or identifiable natural person, household, or business.  Personal Information may include, but is not limited to, your first and last name, home or business address, email address, and telephone number, and information that could be considered Personally Identifiable Information (“PII”) or Sensitive Personal Information (“SPI”).  We may also combine the Personal Information that we collect on our Site with information we collect about you offline.  An IP address may or may not constitute Personal Information depending upon the jurisdiction.  For the purposes of this definition, IP addresses are not included.
  • Anonymous Information is information that does not directly or indirectly identify, and cannot reasonably be used to identify, an individual.

Using the information collected, we may pool Personal Information, Anonymous Information, or both, in a manner that produces a separate type of information - Aggregate Information - which cannot reasonably be used to identify an individual person, household, or business.  For example, we may aggregate Personal Information to calculate the percentage of users in a particular ZIP code.

As part of the Services you choose to use, Ameren may collect certain Personal Information.  For example, we may collect Personal Information when you create or modify an online account, complete a self-service transaction with us online, or provide us with Personal Information in correspondence. This may also include any of your questions, comments, or suggestions submitted through our Site or if you fill out a survey. 

When you voluntarily provide us with a cell phone number or email address on our Site, you are giving us express written consent to use that number for the purpose indicated, or if given with regard to your utility account or other account with us, express written consent to communicate information to you related to your account, so long as you have not given us instructions to the contrary. You may revoke this consent at any time by any reasonable method, including telephone contact with the appropriate Ameren Company or by making adjustments to your account settings online. Your consent to be contacted by us is not required in order to receive our Services.

Chat is a voluntary online service that allows customers of an Ameren Company to speak with customer service representatives of Ameren about their account.  While the Ameren Companies have taken commercially reasonable efforts, including the execution of contractual arrangements with third-parties intended to provide security measures commensurate with those provided by the Ameren Companies, as with any online service, there is some level of risk when communicating over the Internet. In using Chat, you understand that the information that you submit via a Chat session may be documented and retained by Ameren’s third-party Chat provider. While Ameren is committed to your privacy and has made commercially reasonable efforts to ensure the information you submit via Chat remains confidential, we cannot guarantee that such information will remain inaccessible. If you choose to use the Chat function provided through the third-party provider, you disclaim any claims against the Ameren Companies, its employees, or its agents arising out of the information shared.


The information we collect falls into two basic categories:  Personal Information (as defined in this Privacy Policy) and anonymous information.  

We may automatically collect the following types of information as you visit or use our Site:

Please keep in mind that when you provide information to us using a third-party site or platform, the information you provide may be separately collected by that third-party site or platform.  The information we collect is covered by this Privacy Policy, and the information the third-party site or platform collects is subject to the third-party site’s or platform’s privacy practices.  We do not control third-parties’ tracking technologies that are accessible through our Site or how they may be used. If you have any questions about an advertisement or other targeted content, you should read any privacy policy provided by the third-party website or contact the responsible provider directly. Some of these third parties may provide you with ways to choose not to have your information collected or used for targeted advertising. For example, some of these third parties may be members of the Network Advertising Initiative (“NAI”) or the Digital Advertising Alliance (“DAA”), which provide a single location where you can opt out of certain types of data collection or opt out of receiving targeted ads from member companies. To opt out, please visit the NAI’s website at http://www.networkadvertising.org/managing/opt_out.asp or www.aboutads.info to exercise choice with respect to participants of the DAA. 

Ameren may also, from time to time, utilize third-parties for assistance with services such as data analytics, customer feedback management, marketing automation, or other services related to our provision of utility services.  Additionally, please be aware that any third-party service provider websites to which you are redirected for these, or other similar services, may have their own applicable privacy policies, and terms and conditions.

The security of your Personal Information is important to us. We maintain commercially reasonable physical, technical, and administrative security measures to protect and limit access to your Personal Information. We regularly review our security procedures to consider appropriate new technology and protection methods.  

A dedicated Ameren Information Technology (IT) Security group oversees the information security needs and risks with regard to the Ameren Companies, both internally and externally. Although no one can guarantee a transmission over the Internet is 100% secure, we are very concerned with the security of your Personal Information and take the measures such as the use of firewalls and intrusion detection devices, security audits, security alerts, threat monitoring, virus scanning software, and encryption software.

With specific regard to emails, please know that information you send to us via email may not be secure and may be intercepted by others before it reaches us.  Please exercise discretion in what information you send to us electronically. We are not responsible for the security of information that you send to us through email prior to such email being received by the Ameren Companies. 

We hope this information has helped your understand Ameren’s security measures. If you have further questions about Ameren's security measures, please direct them to the Webmaster.
