Where to find your consumer number
Your bill shows a number that identifies your connection. In Sikkim the discom calls it:
| Discom | Name on the bill | Digits | Where to find it | Source |
|---|---|---|---|---|
| Power Department, Sikkim | Contract Acc. No. | 9 | In the right column, at the end of the top block, below Consumer ID. | Sikkim Power Department bill (sample bill, August 2024) |
From the discoms’ own websites, bill guides and sample bills, read on 17 October 2026. Where the source is a sample bill, we read only its layout: the label, the place and the number of digits. A dash means the official page we read does not say. Never share your consumer number with an unknown caller or app.
