This Appendix/Figure applies to the following memorandums:

NPRC 1865.20 - Appendix B-1. Table of Service Number Issuances
NPRC 1865.32 - Appendix B. Table of Service Number Issuances
NPRC 1865.104 - Figure A-1. Table of Service Number Issuances

EXPLANATORY NOTES

1. It was not until February 28, 1918, that the first service number was issued to an enlisted man. Master Sergeant Arthur B. Crean holds the unique distinction of receiving Army service number 1. Officers did not receive service numbers until June 1921. General Pershing, who was then Chief of Staff, receive the number 0-1.

2. In this table, the series are broken down by issuance periods as short as feasible. When not feasible to break down by short periods, effort was made to break down into periods closely corresponding with those covered by specific records groups.

3. For easy reading, numbers are entered in the "Series" column in the conventional style with a comma between each three digits starting from the right, however, no relationship between this and the way numbers are encountered in correspondence and on military records is intended. The most prevalent style in which numbers are encountered in correspondence and records is depicted by the following:
 
 

Air Force 00 000 000 (older usage) or 00000000 (until 7-1-69)
Army 00 000 000 or 00000000
Coast Guard 000-000; 0000-000
Marine Corps 000000
Navy 000000 for Officers
000-00-00 (older usage) for Enlisted;
000 00 00 or B00 00 00 (until 7-1-71) for Enlisted
4. Many groups of numbers issued out of their normal sequence may be inaccurately or incompletely accounted for in this brief table. These are numbers, for instance, which were surplus due to an overestimate of needs in the area or category for which initially set aside. In these cases, however, the table will indicate general trends.

5. "EM means enlisted personnel (including draftees), men as well as women.

6. "Ofcr" means officers and includes warrant officers.

NOTES

1
To Navy Officer SN 8419 only, subnumbers 1 thru 500 were added, appearing 8419-1, 8419-2, etc.
1a
Selected groupings within this series used since 1949 for various categories of Non-Regular Coast Guard, such as WO's, Reserve Officers, etc.  Within this series, numbers 60,000 - 60,393 were assigned from February 1957 thru January 1961.

 In WWI, some Marines in the Army Expeditionary Force were given Army SNs in blocks:  107 951 to 123 280; 270 756 to 272 282; 286 303 to 286 561; and 304 183 to 306 267.  While these SNs no doubt will be reflected in the records involved, the records themselves are filed under the pertinent Marine Corps SNs issued to thes men.
3
Regular Army officers in about 1965 also started receiving numbers in the lower part of the series, with prefix "OF".
4
Various single prefixes used on these.  See Appendix A for an explanation of prefixes.
5
Some of this series were also used for Warrant Officers with prefix "W" and some only the lowest numbers of this series were used for Army Field Clerks with prefix "F".  If these Army Field Clerks became Warrant Officers, they were assigned prefix "W" with no change in basic number.
6

 

 In WWI, some Marines in the Army Expeditionary Force were given Army SNs in the series from 4 604 001 to 4 618 000.  While these SNs no doubt will be reflected in the records involved, the records themselves are filed under the pertinent Marine Corps SNs issued to these men.
