Postal Service

NAICS 491110 · Postal Service · SBA size standard: $9 million average annual receipts

Postal facilities receive, sort, process and dispatch mail and packages according to class, destination and service level. For a station that handles letters, flats, parcels and priority items with daily cutoffs and routes, the specialists turn incoming mail into sorted batches, batches into dispatch plans and load manifests, and manifests into carrier routes and pickup schedules. Rate tables, postage validation, hazardous material rules and chain-of-custody paperwork stay with the postmaster.
