  1. Keep your numbers active with the losing carrier until after the port.
    We are only able to port active numbers. Please do not cancel service with your current provider until after the port completes. We do not recommend scheduling a cancellation ahead of time, since the porting timeframe can be unpredictable.

  2. Determine the correct information that is on file with the losing carrier. Don't guess or use trial-and-error.
    All of the information you submit in the letter of authorization (LOA) must match what the losing carrier has on file. This includes the company name, service address, account number, authorized user, and service address. Remember, the actual carrier may be a different entity from your service provider. The information on file might not be what you expect, especially with VoIP numbers.
  3. Plan for up to four weeks of processing time.
    Porting can be a slow process and we appreciate your patience. The typical timeframe for most ports to be completed is 1-3 weeks. If any rejections are encountered, the process will take longer. Some numbers, such as Google Voice numbers, can be ported as quickly as 24 hours, but this is an exception to the norm. We typically cannot honor requests to "expedite" a port.
  4. Be ready for the port.
    If you make a port request, we assume you and your SIPStation account are ready to accept the ported numbers. You will be able to manage your new DID(s) in your SIPStation account as soon as we receive an assigned port date. You will need to have your trunks and routes set up ahead of time in order to avoid downtime. Ports typically occur at 11:30 AM eastern time on weekdays. Please let us know if you would like a specific date, keeping in mind this works best as an "on or after..." type of request. Although you can request to cancel a port, sometimes this is not possible, especially on short notice (less than 2 days). It's best to make a port request only when you are truly ready.
  5. Communicate with us.
    Sometimes we will need more information from you in order to complete a port, so it's important that we are able to communicate with you. When you first create a number port request ticket, you can expect to receive a response within 3 1-2 business days. If you haven't received this response, please check your e-mail's spam filter. You can also find your ticket at When you open a Port Request with SIPStation as outlined below a ticket is created in our ticketing system and you will receive email updates as the porting process happens.  At anytime you can reply to those emails or even log into the ticketing system with your SIPStation login at by logging in and clicking "My Tickets." The support ticket system is our primary way of communicating with you. If you need an additional person to be added as a CC recipient to the ticket messages, please let us



Please see the current SIPStation Rates (PDF).


In order to create a port request, you will need to first gather some information. Then you'll fill out and digitally sign a Letter of Authorization (LOA) . Finally, you'll create a support ticket in the SIPStation Number Porting department and upload your LOA and bill copy. Full instructions are given below.from within your portal.

Are you planning to port more than one number? Before you proceed, first read our "do's and dont's" to help you decide whether you need to split your request into multiple orders.


Please take time to organize your port request(s) as follows, in order to prevent delays and extra paperwork later: 

  1. Please use one ticket submission for each port request.
    We can port multiple numbers at the same time, but the numbers must be grouped according to #2, #3, and #4 below. Each group of numbers is considered one port request. We can process one port request per support ticket. You can open up multiple tickets if you need to submit multiple port requests. This helps us correctly update you regarding the status of each port.submission but you can create as many submissions as you need. 
  2. Please do not combine local and toll-free numbers.
    We need to treat these as separate port requests because we process them differently on our end. Please create separate port requests for local vs. toll-free numbers.
  3. Please be sure all numbers in a single port request belong to the same carrier.
    Often, especially with SIP numbers, the customer is not aware that their provider is using multiple carriers. Please check with your provider ahead of time to determine if you need to split your numbers into different groups.
  4. Please be sure all numbers in a single port request share the same account information.
    This information includes account number, billing telephone number (BTN), business name, and service address. If you have a complex account, please double-check the configuration with your service provider.

Gathering your Information and Paperwork

Before you fill out your letter of authorization (LOA)port submission, there are a few other things to check:

  1. Is a bill copy available?
    When you request to port-in numbers to SIPStation, we ask that you include a copy of the most recent bill for the numbers. The bill copy must be dated within the past 30 days (issue date, not due date). The bill copy helps prove your ownership of the numbers. It can also help us catch errors. In case the losing carrier rejects your request, we can often use your bill as a means to dispute the rejection. A PDF is best. A screenshot is acceptable if there is no other means of providing a bill copy. If you do not provide a bill copy, we will ask you for one unless you let us know that your numbers are coming from a provider who doesn't give a bill (such as Google Voice). 
  2. Is a PIN required?
    We need to know a personal identification number (PIN) or passcode for certain ports. Please check with your service provider to determine if a PIN will be required. You can advise us of the PIN when you open your number porting ticket in our support system. If you do not provide the PIN but we later determine it is required, we will let you know.
  3. Is a Customer Service Record (CSR) available?
    A CSR is a document describing the configuration of your account. It is an official document that comes from a carrier. While the information on it is coded and looks cryptic, it is extremely useful for us when we are working on your port request, especially if we encounter a rejection. Not all providers will be able to give you a CSR. But if you can obtain one, we greatly appreciate it if you can pass it along to us.
