Bankruptcy Rule 5003 (e), "Register of Mailing Addresses of Federal and State Governmental Units and Certain Taxing Authorities" states:

“The clerk shall keep, in the form and manner as the Director of the Administrative Office of the United States Courts may prescribe, a register that includes these mailing addresses, but the clerk is not required to include in the register more than one mailing address for each department, agency, or instrumentality of the United States or the state or territory. If more than one address for a department, agency, or instrumentality is included in the register, the clerk shall also include information that would enable a user of the register to determine the circumstances when each address is applicable, and mailing notice to only one applicable address is sufficient to provide effective notice. The clerk shall update the register annually, effective January 2 of each year. The mailing address in the register is conclusively presumed to be a proper address for the governmental unit, but the failure to use that mailing address does not invalidate any notice that is otherwise effective under applicable law.”

If yours is a qualifying federal or state governmental unit and you wish to add or update your address, please send an email to
