CommonJS:

const { parse } = require("indian-vehicle-number");

Input may use spaces, dashes or dots and any letter case.

• Standard: SS RR XXX NNNN: a known state/UT code, a 1–2 digit RTO code (not 00), 0–3 series letters, and a 1–4 digit number (not 0000).
• BH series: YY BH NNNN XX: year 21 or later (the scheme started in 2021), 4 digits, 1–2 letters.
• Legacy codes (OR, TS, UA, DN) are accepted and flagged with legacy: true.
• Write the number with spaces when the RTO code is a single digit: GJ51234 is read as RTO 51, while GJ 5 1234 is read as RTO 5.
