Porting-in Phone Numbers


About Porting

The Bandwidth Phone Number API can be used to submit Port-In requests. These requests to move phone numbers from a "losing carrier" to Bandwidth are part of the Local Number Portability (LNP) process. These LNP requests are automatically validated and processed. If the order fails during processing, it will be held for exception processing. Customers can catch and fix exceptions 2 different ways:

  • The customer's application can check the status of port-in orders, and re-submit or cancel them through the API.
  • The customer's LNP team can check the status of port-in orders, and re-submit or cancel them through the Bandwidth Dashboard.

Overview of the Port-in Process

The external events in the porting process are documented in the diagram below.

NOTE: Exceptions are outlined as synchronous and asynchronous in the Appendix A: LNP Exception Codes.

The Orders that are managed by the Bandwidth Phone Number API to implement the above workflow are reported in the order records that are reported through the API calls below. These “order states” comply with the state transitions captured in the following diagram:

Checking LNP Availability

A number or numbers can be checked to see if they can be ported into the Bandwidth Network using an LNPChecker API call.

The fullcheck query parameter values control the components of the response payload that is returned:

fullcheck Query Parameter Behvaior

Parameter value Description
false (default) Return only rate center information
true Additional information will be provided on the losing carriers associated with the listed numbers
onnetportability Provides rate center and losing carrier information for onnet tiers only
offnetportabilty In addition to on-net information return off-net port information in <PartnerSupportedRateCenters> element with Partner/Vendor that the port will be supported on. Contains a list of the TNs that are supported in partner rate centers, and for which we will manually execute a port if requested for help.

Response Description

Element Description
Rate Center information for the indicated set of ratecenters, containing City, State, LATA and the list of TNs for which that Rate Center applies.
The Tier information is provided for offnet rate centers.
Details on the Losing Carrier including name, SPID, whether or not the carrier is a wireless carrier, whether or not account number is required as part of the CSR check, and the anticipated minimum number of days before a FoC date will be granted.

Creating an LNP Order

The API allows a user to create a new LNP order. An order number will be auto-generated and provided to the customer. The order must pass synchronous and asynchronous validation. Synchronous validation will return validation failures immediately in the response. If synchronous validation passes, but asynchronous validation fails, the customer will not receive the error response until they check the order status.

As in other asynchronous workflows, the request to port in a number is created by a POST to a resource dedicated to the purpose to tracking requests – the accounts/{accountId}/portins resource

LOA Upload

After successfully submitting the Create LNP Order request, an LOA may be uploaded using our LOA API.

Supported File Types

The following MIME types are supported for the LOA upload file:

  • PDF(“application/pdf”)
  • PLAIN(“text/plain”)
  • JPG(“image/jpeg”)
  • TIFF(“image/tiff”)
  • CSV(“text/csv”)
  • XML(“application/xml”)
  • WAV(“audio/x-wav”)
  • ZIP(“application/zip”)

CURL Example

Use the order-id returned in the Create LNP Order response.

curl -H 'Content-Type: <MIME Type>' --data-binary "@<Filename>" –iv <Base URL>/portins/<order-id>/loas


curl -H 'Content-Type: application/pdf' --data-binary "@Test_LOA.pdf" -iv <BASE URL>/portins/<order-id>/loas

File Meta-Data

It is often useful to attach additional data to an order in the form of an attached file, and so the existing LOA capability has been extended to optionally allow different file information to be included with a file, to describe type and purpose information. The Meta-Data associated with a file includes a file document name and a document type, which is one of:

  • LOA
  • CSR

Modifying an LNP Order (Supp LNP Order)

The API allows a user to modify an existing LNP order. To do so, the order Id that was generated in the create LNP order request must be provided. Modifications are only allowed for orders that are not yet complete or cancelled. LNP orders can be modified with a PUT to accounts/{accountId}/portins/{orderId}. Since many of the entries in an LNP Order cannot be changed after the initial order is placed, the PUT on a porting order-id does not require that the full order payload is included. Items that can be included in a SUPP request include:

  • CustomerOrderId
  • RequestedFocDate
  • BillingTelephoneNumber
  • NewBillingTelephoneNumber
  • AccountNumber
  • PinNumber
  • TnAttributes elements
  • Subscriber elements
  • SiteId
  • PeerId
  • PartialPort, and
  • LoaAuthorizingPerson
  • ListOfPhoneNumbers
  • Triggered
  • Immediately

If the order ProcessingStatus is DRAFT, the rules about what can be changed are much more relaxed. Validation is performed when the ProcessingStatus is changed from DRAFT to SUBMITTED. The AltSpid element can be modified if it is not configured at the system level.

ProcessingStatus - you can only provide this field with a value of SUBMITTED if the current ProcessingStatus of the port-in is DRAFT.

When a port-in is being processed by off-net partner Level 3 (you can tell this because /lnpchecker indicates a Port Type of AUTOMATEDOFFNET), the rules for what can be changed in a SUPP operation are more restrictive. If the order has NOT yet received FOC, you may change the following:

  • RequestedFocDate
  • BillingTelephoneNumber
  • SubscriberType
  • Subscriber name elements or BusinessName, provided that SubscriberType is provided

After the FOC date has been received, the billing telephone number and subscriber information cannot be modified, only the FOC date/time can be updated.

Canceling LNP Order

The API allows a user to cancel an existing LNP order. The order number that was generated in the create request must be provided. The status of the order shall not be marked as COMPLETE i.e. you cannot cancel a completed order. The DEL method is used for this purpose.

Activating Ported Numbers

The by default the Bandwidth Phone Number API will activate ported wireline numbers shortly after 11:30 am on the FOC date.

The Bandwidth Phone Number API will also support customer “on demand” activation of numbers on the FOC date, if the intent to use the “on demand” activation is declared when the Port Order is created. This declaration is done by including a <Triggered> element in the /portin order request.

If on demand activation is indicated, then the customer will specify a default activation time in the initial port request, and can request activation of the port at any time up until that default activation time. If a port has not been activated by the default activation time, the Bandwidth Phone Number API will activate the port.

If activation by the default activation time on the FOC date is not achievable it is possible to delay activation for up to the third day after the FOC date, acknowledging that the losing carrier may have removed service from TN on the FOC date.

Activation and management of on-demand ports is done via the activationStatus resource. The activationStatus resource is created by the system when activation is available for the port request, and can be modified by PUT to activate the port, or to delay the activation in the case that the manual activation cannot be completed on time.

Payload Parameters

Parameter Required Type Description
AutoActivationDate Yes Date This date controls both the activation of the Port, and delays in activation of the port.

- If AutoActivationDate is in the past, then the port will be activated
- If AutoActivationDate is in the future then the port will be delayed until the specified time, as long as that new time does not validate other restrictions on the activation of the port. The typical guard time applied to this capability is 3 business days.
