What kinds of records are available to law enforcement?
  • Bill Statements

    CenturyLink will only provide copies of a customer's bill statements with a subpoena, court order, or other legal demand specifically requesting this information. Applicable fees may apply.

  • Call Trace Results (*57)

    *57 can be used at any time, but will only trace the last incoming call.

    A successful *57 trace means that CenturyLink captured a 10-digit phone number. Please note that there is no guarantee that the 10-digit phone number is a valid working phone number (e.g. 000-000-0000).

    Unsuccessful traces indicate that CenturyLink did not capture a 10-digit phone number.

    Customers are advised to contact their local Law Enforcement Agency once the call is traced. The trace results will only be released with a subpoena, court order, or other legal demand. A successful trace will include the phone number captured and if that number is serviced by CenturyLink, the name and address of the subscriber will be released. If Law Enforcement has any questions regarding this process, please call the CenturyLink Law Enforcement Support team at 877-451-1980.

    For additional FAQs about the Call Trace feature, see our Customer FAQ section on threatening, obscene or verbally harassing calls.

  • Internet Protocol (IP) Subscriber Information

    Internet Protocol information may include the name, address, associated phone number, user ID and time logs of the assigned CenturyLink customer. CenturyLink cannot process requests for IP subscriber information without being provided an exact date, time and time zone. Please note that NO information will be released without a subpoena, court order, or other legal demand specifically requesting this information. Applicable fees may apply.

  • Local Call Detail

    CenturyLink customers are charged for dial tone, not per call; therefore local call detail will not appear on their bill.

    Records of local calls are not maintained in the normal course of business. To attempt to retrieve local call detail, CenturyLink must perform an extensive search of raw switch data and then attempt to assemble the relevant data into a report that can be understood by the requesting party. There is no guarantee that any particular local call record will be obtained. Applicable fees may apply to any requesting party, including Law Enforcement agencies because this is data that is not maintained in the normal course of CenturyLink's business. NO information will be released without a subpoena, court order, or other legal demand specifically requesting this information.

  • Pay Phone Records

    CenturyLink is a rebiller of payphone services. We can provide the location of a payphone without a subpoena since that is public knowledge.

    CenturyLink can only provide call detail records on a payphone with a subpoena, court order, or other legal demand and only if it is on CenturyLink's network.

    To attempt to retrieve call detail, CenturyLink must perform an extensive search. There is no guarantee that any particular call record will be obtained. Applicable fees may apply to any requesting party, including Law Enforcement agencies.

  • Payment

    Payment information may include records of bank, credit card or electronic fund transfer payments. Please note that NO information will be released without a subpoena, court order, or other legal demand specifically requesting this information. Applicable fees may apply

  • Subscriber

    Subscriber, or customer, information may include customer name, physical address and billing address. Please note that NO information will be released without a subpoena, court order, or other legal demand specifically requesting this information. Applicable fees may apply.

  • Toll / Long Distance Call Detail

    An itemized list of outgoing toll/long distance calls, incoming collect calls, calling cards or third party billed calls may be available on a billing statement. If a customer has an unlimited long distance plan, an itemized list may not appear on the billing statement. Prior to billing, CenturyLink may not be able to provide all information that will ultimately appear on the customer's billing statement. NO information will be released without a subpoena, court order, or other legal demand specifically requesting this information. Applicable fees may apply

  • Voice Messaging

    Access to a CenturyLink customer's voice mail messages requires a search warrant or court order. CenturyLink cannot retrieve voice-mail messages once the customer deletes the message, or once the customer's service has been disconnected.

Does CenturyLink track Internet content?

CenturyLink uses information generated on our networks to manage, plan, and develop networks, and to ensure reliability and efficiency of those networks. For example, we monitor data to check for viruses, control spam, prevent attacks that might disable our services, ensure traffic does not violate our subscriber agreements or our acceptable use policies, and guard against other inappropriate or illegal activity. This may involve looking at the characteristics of our network traffic, such as traffic volumes, beginning and ending points of transmissions, and the types of applications being used to send traffic across our network.

In limited circumstances, we need to look into the content of the data (such as the specific websites being visited, files being transmitted, or applications being used) for the purposes described above. We may also look into the content of the data when CenturyLink is concerned about fraud or harassment, to repair a detected problem, or when we are providing the content of broadband traffic to Law Enforcement when required and authorized by law.

Most of the specific information we obtain that is attributable to a user is kept only for a matter of hours or days. We may retain data for longer if, for example, we see patterns in the traffic that give us concerns about potential harm to our network, or if we are doing a specific study on the impact of certain applications used on our networks. We also may retain logs of the total amount of data transmitted, and the date, time, and duration of access to the Internet through our services by a user, including the user's IP address at the time.

What is the difference between a Dynamic and a Static IP Address?

Dynamic IP Addresses change every time a user connects to the CenturyLink network. The majority of CenturyLink customers have Dynamic IP addresses. IP addresses are not specific to a certain city or state. The customer may be issued any IP address that is assigned to the switch's service area. The switch may cover multiple cities and states.

Static IP Addresses remain the same and are typically used by Large Businesses or Government Entities.

If I know the IP Address, how do I find the Internet Service Provider?

You can access the American Registry of Internet Numbers (ARIN) website to identify the Internet Service Provider of an IP address. Use the "Search WHOISRWS" function located on the top of ARIN's home page.

ARIN is not maintained by CenturyLink. CenturyLink cannot ensure the accuracy of the results provided by ARIN.

How do I find the Service Provider for a telephone number?

Telcodata is a website that will locate the name of the Telecommunication Service Provider when provided with an area code and prefix. This site will also break down the area code and prefix on "pooled numbers" which are numbers split between several different service providers. For example, 720-287 is pooled between 4 different service providers. Telcodata will show which Service Provider handles each pooled set of numbers.

Telcodata is not maintained by CenturyLink. CenturyLink cannot ensure the accuracy of the results provided by Telcodata.
