Port Your Telephone Number to Flowroute

We are thrilled you're trusting Flowroute for your VoIP carrier services. This step-by-step guide introduces the process of porting your current numbers to Flowroute. Follow these steps below to create your port order and get your port order submitted. If you still have any questions after reading through, know that our support engineers are a phone call away.

Before you begin

Have the following before starting a port order:

  • The list of telephone numbers you want to port to Flowroute. You can enter a list of telephone numbers individually or upload a CSV, TXT, XLS, or XLXS file.
  • PDF copies of bills from your current service provider for each telephone number you want to port. Copies of invoices must be in PDF format for uploading.
  • If you are porting multiple numbers from multiple accounts or carriers, you must submit separate port order requests for each account and carrier, as well as separate bills; however, each application can contain multiple numbers for that account or carrier. If you submit a single request containing multiple accounts and carriers, the request can be rejected and returned to you to correct.

  1. Log on to your Flowroute account.
  2. Click DIDS, and then click Port Orders.
  3. Do either of the following:

Create a Port Order

Follow these steps if you are reasonably sure there is no issue with porting your telephone number(s) to Flowroute. If you are unsure, you can quickly check whether or not Flowroute can service the telephone number by first clicking 'Check Telephone Number Portability.'

  1. On the Port Orders page, click Create Port Order.

    The Port Order details page appears.

  2. In the 'Enter your number(s)' field, add each number you want to port using the (NPA) NXX-XXXX convention. e.g. (206) 123-1234

    Or, if you have a file containing any number of telephone numbers that you want to upload, click Browse and navigate to the file location.

    NOTE: Supported file formats are CSV, TXT, XLS, and XLSX.
    IMPORTANT: Do not submit a single port order where you have telephone numbers on multiple accounts or with various providers. Providing a single port request with telephone numbers from multiple accounts will result in rejection. Create separate port orders for each account and carrier.

    After successful porting, these numbers will be consolidated under your Flowroute account.
  3. In the Existing Account Information section, complete all required information on the page. Fields with needed information display with an asterisk (*). 

    IMPORTANT: It is crucial that you provide information in these fields precisely as it is in your agreement with your carrier. For example, your first name and last name for the Name (Authorized Contact) is required to be precisely the same as the losing carrier's records. The verification process does not include suffixes such as Dr. or Jr. During the submittal phase; if there is a mismatch, the request is rejected and returned to you to correct. Providing the correct information at the start reduces the time frame it takes to complete the request. If you have questions about how the information appears with your carrier, contact your current service provider to get a customer service record (CSR). The CSR lists the exact information the provider has on file for the porting telephone numbers. This information is what the carrier requires and is better than any other provided.
  4. Optionally, in the Existing Account Information section, you can

    • Set the 'Desired completion' date. Requested completion dates must be Monday-Friday, except for holidays. You can request a change in the port order completion date if you have already submitted the request; however, if the port order was accepted for completion and is due to be completed within 48 hours, having the date changed is more difficult and often unable to be completed. Otherwise, if you leave the field blank, the porting team assigns the first available date.

    • Enable CNAM Lookup. Selecting this option allows your setup the option to see the CNAM(Caller ID) information of the calling party. There is a $0.0039 per lookup charge for this service.

  5. At the bottom of the page, click Continue.

  6. Verify the information on this page.

    Because you have not yet submitted the port order, the status will display as Pending. See Port Order Process for more information about the different statuses associated with a port order request.

  7. Click Continue order.

    The Port Order page appears, prompting you to upload a bill copy dated within the last 30 days. This page also shows a summary of your request information, as well as allows you to add or edit any numbers, or to cancel the order completely.

  8. Click Browse and navigate to the location of your bill. You can also upload any other supporting documentation as well. After selecting each file to load, click Upload File.

    The Submit for Approval page appears.

    NOTE: Not sure what documentation to upload? See Required Documentation for Porting Telephone Numbers.
  9. Ok, just a couple more clicks and your order is submitted! Click Submit for Approval.

    A popup Agree to LOA page appears, prompting you to sign the Letter of Agency.

  10. Digitally sign the Letter of Authorization by clicking I Agree this is correct at the bottom of the page.
  11. Your part is done! Keep an eye on your email inbox or the Order History page for the current status of the port order.

    So now what happens?


Check Telephone Number Portability

  1. Before submitting a port order request, you may want to first check whether or not Flowroute can service the telephone number you want to port.

  2. After logging on to Flowroute and going to the Port Orders page, click Check number portability.

    The Lookup Coverage page appears.

  3. In the Enter your number(s) field, add each number you want to look up.

    Or, if you have a file containing any number of telephone numbers that you want to look up, click Browse and navigate to the file location.

    NOTE: Supported file formats are CSV, TXT, XLS, and XLSX.
  4. Click Lookup Coverage.

    Success messages display for each number that can be covered by Flowroute. Failure messages are returned for telephone numbers that cannot be covered by Flowroute.

  5. With this available information, you can now create a port order request.

So what happens next?

The information provided will be validated, and if everything looks good, a port request will be submitted to your current provider. Once the port order is submitted, it can take 2-4 weeks to complete. The time to completion largely rests on the accuracy of the information you have provided and the speed with which your current carrier processes the request. Rest assured, any updates regarding the port progress will be sent to you through email. Also, the Port Order page has a comments section where we let you know any changes in status or problems. We will continually keep you informed as things change.

If any issues occur during the porting process arise, we'll let you know immediately and provide you with guidance on how you can move the port request forward. If no issues occur, you'll be notified via email and through the Order History page of the completion date for your port. 

If you have any questions during the process, either while creating your port order or after submitting it, you may contact either our support engineers at or the porting team at
