Copyright 1999 by Veltisezar B. Bautista. Testing centers are main offices generally known as District Offices, General Mail Facilities (GMF), and Management Section Centers (MSC). Needless to say, this directory is very valuable for finding a Post Office job. If you want a postal job, call all the testing centers in your state, especially those in your area, at least once a week to find out if there are any examinations coming up. If you are thinking of moving to another state, call the testing centers in that state at least once a week. Always reach out and touch someone! If there are openings in another city, fly there and apply for examinations. Go where the action is! A Directory of U.S. Postal Testing Centers is included inThe Book of U.S. Postal Exams:How to Score 95-100% and Get a Job by Veltisezar B. Bautista.
