- Section 46 of the CGST Rules, 2017 provides that invoice may have “a consecutive serial number not exceeding sixteen characters, in one or multiple series, containing alphabets or numerals or special characters hyphen or dash and slash symbolised as “-” and “/” respectively, and any combination thereof, unique for a financial year”.
- Therefore, a supplier can have multiple series for the same year, so long as the same series is not used across financial years. Therefore, you may have a different invoice series for each location having consecutive serial numbers running across that series.
