Format, years and the law

Format
999-999, for example 외교 321-678 (9 any digit)

The hangul is a word, not a syllable: 외교 for diplomats, 영사 for consuls, plus 준외, 준영, 협정, 대표, and 국기, which reads like "national flag" but abbreviates 국제기구, international organisation. What the hyphenated digits encode is nowhere published.

외교
외교관용 (diplomatic mission)
영사
영사용 (consular)
준외
준외교관용 (quasi-diplomatic)
준영
준영사용 (quasi-consular)
국기
국제기구용 (international organisation)
협정
기타외교용 (협정) (other diplomatic, agreement)
대표
기타외교용 (대표) (other diplomatic, representative)

The format above follows the issuing rules: a registration that fits it is one this series could have issued.

About this plate
THE DARK-NAVY DIPLOMATIC PLATE, and the only Korean plate that prints a separator glyph, a hyphen with its own 22.5 mm cell between two three-digit groups. It is also the only Korean plate whose hangul element is a WORD rather than a syllable and the only one where that element comes FIRST. The colour, 감청색, is given as a Munsell notation (7.5PB 2/8), not a coordinate, so the hex is an approximation and the notation is the claim. Six further diplomatic categories share the plate and are recorded as a variant. No decode of the digits is published: whether 321-678 encodes a mission is not stated in the notice and is not guessed here.
About the format
The hyphen here is REAL: Annex 8 draws it as a glyph with its own cell between the two three-digit groups.
