Sample Reference No.
04 1416 1234 5678
Exactly 14 digits — no dashes, no spaces, no letters.
Exact Location on the Bill
On almost every Pakistani electricity bill, the reference number is printed in the top-right corner, just below the DISCO logo and consumer address block. It is labeled "Reference No." or "Ref No.".
DISCO Differences
All DISCOs follow the same 14-digit format, but placement and surrounding labels can differ slightly. The first few digits encode the regional sub-division code; the remaining digits are the consumer ID.
