1. Standard registration numbers
Most Indian plates have four parts: a two-letter state or UT code (such as MH, DL, KA or TS), a district code, an optional series of letters, and a four-digit number. For example: TS 09 AB 1234.
2. Bharat (BH) series
BH series plates start with the two-digit year of registration, then BH, four digits and one or two letters, for example 22 BH 1234 AA. Any valet system used in India should accept them.
3. Common mix-ups
Whether a plate is typed by hand or read by a camera, the same confusions appear: the letter O and the digit 0, I and 1, Z and 2. Because each position in an Indian plate is either a letter or a digit, many of these can be corrected automatically.
