Check the top section of your electricity bill
Look for labels like BU No., BU Number, Billing Unit, or Section
Find the consumer details area on the bill
Check near the consumer number, subdivision, or division details
If using a digital bill, search within the PDF for “BU”
On MSEDCL bills, the BU number is usually printed near the billing office or jurisdiction details
If you still cannot find it, contact your local MSEDCL office or customer care with your consumer number
