GN 00904.010 Determining Servicing Office
Each FO has a defined geographical service area, and is responsible for providing
service to any individual whose mailing address falls within this service area. In
this capacity, the FO is referred to as the “servicing office” for a particular individual or address. To find out which FO serves an address in
the United States, determine the county from the geographical code book or the United
States Directory of Post Offices; then refer to the Service Area Directory, Part B.
If the individual prefers to contact an FO other than the servicing office, see GN 00904.064.
Auxiliary claims and other claims filed by nonprincipal claimants should be completely
processed in a servicing nonresident office, UNLESS there is a claim pending on the
primary beneficiary in the resident office. For purposes of GN 00904.010 — GN 00904.120 a claim is considered pending when it is part of a district office pending file;
conversely a claim is no longer pending after it is completed and cleared from the
district office pending file.
The servicing offices for all mailing addresses in the U.S. are listed in part B of
the Service Area Directory (except certain military addresses—see GN 00904.025).
Note: When a caller phones a field office to inquire about the telephone number or address
of another field office, employees are encouraged (to the extent possible) to utilize
all available resources and take all actions necessary to accurately respond to the
inquiry/report while the caller is on the telephone.
