Use this Port-Out Request tool to port from Level 3 Communications (SPIDs 7058, 7150, 8318, and 8824).
Please register with the tool to process your telephone number (TN) port-out request. The tool works with Microsoft® Internet Explorer® v6.0, 7.0 and 8.0 with a 128-bit cipher strength. Other browsers may work, but have not been tested for compatibility.
Note: All times shown in the tool are GMT, but we will follow the timing intervals set by the FCC based on the time zone for the telephone number, not based on GMT.
You can request a TN port out using the Port-Out Request tool 24/7. Our support staff is available to help you by email Monday–Friday, 7:00am–4:00pm MT excluding the following holidays when our offices are closed:
A simple porting request is defined as a single TN on a single account. Simple requests are processed within four hours of the request and can be ported within one business day.
A non-simple or complex porting request is defined as any request involving more than one TN. Non-simple/complex requests are processed within 24 hours of the request and can be ported out in four business days.
Not all telephone numbers have a customer service record (CSR). We use our best efforts to provide CSR information for requests (if available).
For simple ports, CenturyLink does not require a recent letter of authorization (LOA) signed by the customer of record; however, we reserve the right to request one at any time. It is the requesting provider’s responsibility to have a valid authorization on file. The local service provider (LSP) should have a copy of the end user's LOA on file. We do require an LOA for any requests related to managed-modem or dial-up-internet service.
To process a request for TN port out, the TN must be a valid Level 3 telephone number on the Level 3 network. The following service provider IDs (SPIDs) are owned by CenturyLink (formerly Level 3) and you may submit your request for any TN associated with these SPIDs: 7058, 7150, 8318, and 8824. If you are trying to port out against other SPIDs please contact the appropriate service provider for those requests. CenturyLink is only able to process port out requests against legacy Level 3 inventory.
To process your request, we require that the customer information submitted on the local service request (LSR) match our records. In addition, we require a 24-hour notice of changes and cancels prior to your firm order confirmation (FOC) date to ensure continuity of service. FOC dates are valid for five calendar days including FOC date. CenturyLink does not provide concurrence; the carrier provider is expected to build NPAC subscriptions in enough time for auto-concurrence. You cannot create an NPAC subscription prior to receiving your FOC.
Note: The following four fields are required on the LSR: PON, VER, ATN, and CRD.
You can check the status of your LSR in the Port-Out Request tool.
Due to realtime provisioning constraints, CenturyLink does not accept snapback requests. If you wish to disallow a prior port request and return the TN to CenturyLink, follow CenturyLink's winback process. Where possible, we use our best efforts to work around this rule for first responders who are out of service, but system limitations may prevent us from accepting snapbacks even in these situations.
If you run into an issue, use the following list escalations. You must follow the escalation path in order—please don't skip a level—you will be auto-routed to the appropriate level if you escalate out of process. We respond to all escalations within 4 business hours if the escalation is received between 7:00am–3:00pm MT. If you escalate after 3:00pm MT, you may not receive a response until the next business day.
Use this tool to port from legacy Global Crossing (SPID 7343).
Centurylink ports telephone numbers in accordance with applicable regulatory rules and industry guidelines.
