AP not confirmed yet in passenger. Reported for Apportioned Truck. Jeff Ellis reports that no AS, AT, or AU series plates were issued.
The "Taxation Without Representation" legend began with the AZ series and appears on the BA, BC, BD, BE, BF, BG, BH, BK, BL, BM, BN, BP, BR, BS, BT, BU, BV, BW, BX, BY, BZ, CA, CB, CC, CD, CE, CF, CG, CH, CJ, CK, CM, CN, CP, CR, CS, CT, CU, CV, CW, CX, CY, CZ, DA, DB, DD, DE, DF, DG, DH, DJ, DK, DL, DM, DN, DP, DR, DS, DT, DU, DX, DY, DZ, EB, EC, ED, EE, EF, EG, EH. EJ, EK, EL, EM, EP, ER, ES, ET, EU, EV, EW, EX, EY, EZ, FA, and FB series. BI, BO, BQ, CI, CL, CO, CQ, DC*, DI, DO, DV, and DW have not been reported, so they were apparently skipped. (*DC was not used for Passenger, but the DC series does exist in the form of Government Fleet plates with DC stacked, and a DC flag representation in the place of the second letter, and a four numeral serial following.) The BB, BJ, and EA series have the alternate legend with the District's web site address. The BB series is embossed, with "WWW.Washingtondc.gov" slogan, with that odd capitalization, although these didn't appear to make it all the way to BB 9999, and the BJ series is flat, with "www.washingtondc.gov" slogan.
DV was used for Disabled Veteran.
Embossed high: BG 1673
Flat low: BG 2033
DC changed from license plate validation stickers to windshield validation stickers on 22 APR 02. Plates have been seen with stickers reading "See windshield sticker" in the usual sticker locations on the plate. Newer issues have it screened on the plate.
Wally Punzmann reports the highest DC taxation plate with the "Washington, D.C." script at the top before it went to the "WASHINGTON, DC" block font is BP 0908. The switch to the "WASHINGTON, DC" block font may have occurred at BP 1000.
DM series plates seem to be back to the full-height serial font, but somehow the characters appear to have more space between them horizontally, as though the stroke is narrower.
The EA series is appearing with the website. Although it is higher than the "Taxation" standard issue, we will continue to report the "Taxation" series as the high since it is the standard issue.
EA website high: EA-1714 2015-11-19 Dave Edmondson
As with EC, ED seems to have started even though previous series was nowhere close to 9999.
According to David Nicholson, starting in the EK series, the "WASHINGTON, DC" inscription is changed to "DISTRICT OF COLUMBIA". This has apparently led to visibility issues, with some plates reading "STRICT OF COLUMB" due to the boltholes obstructing part of the text.
