About MBI Administration
The sole purpose of MBI Administration is to manage MIN Block Indicators (MBIs) for US and Puerto Rico wireless service providers (WSPs). While providing all of the tools that WSPs require to maintain their inventories, we work to protect those inventories and ensure that your asset usage is trouble-free. We do this by:
  • Ensuring fair and timely assignments;
  • Preventing duplicated assignments;
  • Protecting the rights of the registered users; and
  • Providing a dispute mechanism for service providers.
We received our mandate from the industry in response to Federal Communications Commission orders to provide nationwide roaming and industry concerns regarding the management of the global pool of MBIs. We are the only approved administrators of MBIs for the US and Puerto Rico.
