United States Postage Meter Stamp Catalog/Sub-group PO-B – Stamps generated by machines or systems unique to Post Office use, with no resemblance to any commercial meter stamp

Sub-group PO-B: Special Post Office machine stamps with no counterpart among general use meter stamps

 * The earliest stamps included here come from machines designed for franking parcel post, i.e. they could weigh parcels and produced stamps on adhesive tape. Later machines also included a weight scale and produced stamps on tape but they were designed to frank all mail, not just parcel post.

USPMSC: POX-A1 

'''PO-B1. International Business Machine''' (MV), February 6, 1935 to May 23, 1938.
 * IBM built six or possibly seven machines designed primarily for franking parcel post but which were used for other classes of mail as well. The machine included a weight scale as an integral part.
 * The stamps are similar to Group E stamps in that they are printed on tapes of the same size and have groups of wavy lines in the corners.
 * "U.S. POSTAGE" at top, meter number and town name at bottom
 * Meter number with "METER" prefix and "P.O." suffix
 * Across the center are a serial number, the weight and zone, and the value figures at right.
 * Five machines were trialed:
 * A. MeterCat 5 spaces.jpg 00001 MeterCat 5 spaces.jpg  NEW YORK, N.Y.  MeterCat 5 spaces.jpg[RR]
 * B. MeterCat 5 spaces.jpg 00002 MeterCat 5 spaces.jpg  WASHINGTON, D.C.  MeterCat 5 spaces.jpg[RRRR]

 * a. With "FEE" replacing weight and zone number in center of stamp, intended to indicate payment for extra services such as special delivery, insurance, etc.

NOTES:
 * Meter 00007 was reportedly used for a short time by retailer Montgomery Ward in Chicago, Illinois, not in a post office. Examples have never been seen or reported by collectors.
 * Meter 00006 presumably was built but no information about the machine has been found.
 * Nearly all the stamps known are loose tapes. A small number are known affixed to small cut-outs, but only a single PO-B1 stamp is known on large, cover-size piece, shown at right.

USPMSC: POX-B1 

'''PO-B2. National Cash Register''' (MV), 1959. [Extremely rare, value unknown]
 * Used in Alexandria, Virginia post office for five months in 1959.
 * Although about 50,000 stamps were sold, only a single cover with two 2-cent stamps affixed is known to survive.
 * "U.S. POSTAGE PAID" at top above "N.C.R. METER No. 1234" and "Alexandria, Va. P. O.".
 * The date is in the center, and the value figures are at the bottom.
 * Columns of arcs are located at both sides. Possibly these are end-of-roll markings and not part of the stamp design.

 * a. Date with 3-letter abbreviation for the month MeterCat 5 spaces.jpg[RRR]

NOTES:
 * Shown at right is a receipt for the stamps.
 * This stamp came into use in late March or early April 1986. Most Intermec machines were removed from service by the end of 1989 although a few in Tampa remained in use as late as the summer of 1993.
 * The early labels used in Vienna, Virginia did not have anti-peel slits. Starting in late 1986 or early 1987 labels with anti-peel slits cut into the edges came into use. All stamps from the other locations were printed only on labels with anti-peel slits. The Vienna stamps without the anti-peel slits are relatively scarce.
 * Most Intermec stamps available are mint tapes sold to collectors. Non-philatelic covers franked by this stamp are rare [RR].

♦ Machine I8600165 is known with two different town marks, "SAINT PETE / FL PO 33730" and "ST PETE / FL PO 33730". Other machines may also have been used with more than one town mark.

USPMSC: POX-F1

'''PO-B6.1. MOS Corporation/UNISYS''' (digital), April 16, 1992.
 * This was the third trial in the "PVI" series and the one that was approved for general use. The system consisted of an "Integrated Retail Terminal" designed by MOS and a "Postage Validation Imprinter" designed by UNISYS.
 * Large round-cornered self-adhesive labels with red, orange or pink stripe along the top.
 * At left is a right-facing standing eagle with wings raised.
 * At center right, "U.S. POSTAGE/ PAID"/ town line/ ZIP code/ date/ "AMOUNT"/ value figures/ identification number.
 * The identification number consists of an 8-digit machine number and a 2-digit operator number (00000000 – 00).
 * V/F: MeterCat 5 spaces.jpg $0.00 MeterCat 5 spaces.jpg$00.00


 * a. Without bar code, used for any class of mail.
 * b. First day cover MeterCat 5 spaces.jpg[RR]♦
 * c. With town line "UNIT CITY STATE" and either the actual ZIP code or "00000".

NOTES (These apply to other PO-B6 types as well):
 * Town name abbreviations and mispellings are not especially rare. Doubled state abbreviations are relatively common.
 * The ink tends to fade on these stamps except on the very earliest stamps. The printing method must have been changed at some point, to reduce costs perhaps, and the change resulted in a fugitive imprint.
 * For mail brought to the post office clerk with postage applied, the machine would print non-postage labels showing a barcode of the destination ZIP code. The machine could also produce labels with a tracking number barcode, both labels shown at right.

♦ The system debuted on April 16, 1992 at four post offices in and near San Diego, California: Escondido, Solana Beach, San Marcos, and the Tierrasanta Postal Store in San Diego. A fifth location, Golden Triangle Postal Store in San Diego was supposed to start using the system on the same day but because of difficulties did not begin using the system until April 18th. The MOS/UNISYS system was considered such a success that in May 1992 the Postal Service began fielding them to most post office throughout the country.
