What is a Firm Order Commitment (FOC)?

An FOC (Firm Order Commitment) is a confirmation from a current service provider that a Service Order to port a telephone number will be fulfilled, stating the date that the current carrier will comply with the request stated in the Service Order.

FOCs may not be applicable when switching mobile phone numbers. Depending on the phone carrier, this may require a different process.

What is a Firm Order Commitment (FOC)

What Does FOC Mean

An FOC is provided by the losing service provider (also may be known as current service provider). This is done in response to a port order issued to them to move a number from that providers’ network to another (known as the winning or new service provider) service providers’ network. A FOC is a positive order acceptance response and includes the date the losing/current carrier will release the number to port to the winning/new service provider.

An FOC can refer to landline phone services as well as internet services relevant to that line, such as DSL. In the case of LECs (Local Exchange Carriers), an FOC is specifically related to the movement of a port from one provider to another. For example, if you want to switch your home phone service from Verizon to AT&T, then Verizon will issue an FOC. In this case, the FOC is a commitment that the telephone number in question will be ported to the new provider at a certain date or time.

FOCs may not be applicable when switching mobile phone numbers. Depending on the phone carrier, this may require a different process.

What is a FOC date

The issuance of an FOC signals the end of the porting process. Once an FOC is issued, you must cancel a port at least 72 hours before the date. FOCs do not guarantee any time other than before the end of business on that date.

What are the different LNP Status Updates

Pending - Means the your order has been received

Submitted - Means your order has been submitted to our processing vendor and the losing carrier has been notified

Exemption - Means your order was rejected by the losing or existing service provider and you must provide the updated information they are requesting.   This could be for a wrong address, wrong business name, wrong authorized contact etc…

SUP - This means the order has been resubmitted.  For example, going from an Exception to a SUP means the order was updated with your new information

What is LNP (Local Number Portability)?

Local Number Portability (LNP), also known as number portability and number porting, enables end users to keep their telephone number when switching from one telecommunications service provider to another. Prior to the introduction of LNP, changing service providers meant having to get a new telephone number. Number porting changed that, making it possible for consumers to retain the same telephone number.
