The current standard plate, in production since the 1ABC123 format exhausted in 2026 — the same red-script-on-white design California has used for three decades, just mirrored.

When 9ZZZ999 ran out in 2026, California simply mirrored the format and restarted at 000AAA1. The plate looks identical — only the arrangement flips, and the slow series counter now lives in the last digit, which will read 1 for years to come.

## About this plate

CALIFORNIA'S CURRENT STANDARD SERIES. It happens to coincide with the reported real start, secondary sources (Wikipedia citing the Sacramento Bee and Fox5 San Diego) put the flip at MARCH 2026, immediately after the 1ABC123 format exhausted at 9ZZZ999, but no DMV instrument stating the date was obtained, so the month is not claimed and the year is claimed only as a bound. THE FLIP ITSELF is the interesting structural fact: California does not redesign when a format runs out, it MIRRORS the existing one, which is why the base design has outlived two complete serial systems. A parse API must therefore treat 1ABC123 and 123ABC1 as two series of one visually identical plate.

## Region code notes

California encodes no geography in the plate string and prints no county legend. The only county artefact is administrative (VIRPM Chart 2 - County Codes, used in DMV records, never on the plate).

## How numbers are issued

Mirror of the exhausted 1ABC123 format: the three leading numerals advance and the letter group follows. REPORTED, not sourced, the DMV publishes no progression rule that was located.

## About the format

REPORTED LETTER-POSITION RULE, NOT ENCODED: secondary sources state that I, O and Q are used only as the MIDDLE letter of the three-letter group (the fifth character in 123ABC1, the third in 1ABC123). The underlying citation chain is Wikipedia -> a San Jose Police Department training PDF, which is not the issuing authority.

## Replacement

note: CALIFORNIA HAS NO REPLACEMENT CYCLE. No periodic-replacement duty was located in the Vehicle Code, and VC § 4850(d) affirmatively provides that owners of nonreflectorized plates need not replace them. VIRPM 21.260 and the Year of Manufacture rules take for granted that 1963 plates remain in service.
