Letter of Authorization

A Letter of Authorization (LOA) is a legal document in which the executing party makes certain assertions to a service provider about their authorization to switch (port) services and telephone numbers from one provider to another. Traditionally this would be a paper document requiring an actual signature, but currently the industry supports LOAs which may be generated from a variety of electronic and verbal methods.


How Bandwidth is Involved with LOA

Bandwidth requires its customer to obtain an LOA for all port in orders. While Bandwidth may not require that an LOA be included when submitting a port in order, we do require that our customers are able to provide an LOA to us when requested.


What Are the Benefits of Bandwidth’s Involvement with LOA

An LOA helps to ensure that telephone numbers are not moving between carriers without the authorized end users’ permission.
