The electricity reference number is the 14-digit code printed on every WAPDA DISCO bill that serves as the account identifier for online bill checks and digital payments — it's distinct from the shorter meter number on the same bill.
Look at the Top Section of Your Paper Bill
Every WAPDA DISCO paper bill has a header section at the top — this is where your reference number lives. The exact label differs slightly by DISCO:
- LESCO, MEPCO, FESCO, GEPCO: labeled "Reference No."
- IESCO: labeled "Ref No." or "Account No."
- PESCO, HESCO, QESCO: labeled "Reference No." or "Consumer No."
- K-Electric: labeled "Account No." or "K.No."
The number is always in the upper portion of the bill — never buried in the middle or at the bottom. On WAPDA bills, it's typically in the top-right block of consumer information alongside your name and address. On K-Electric bills, it's usually in the top-left area of the account summary box.
Take a photo of this section right now and save it in your phone's gallery in an album named "Important Documents." You'll never have to hunt for it again.
Identify Your DISCO to Know the Reference Number Format
Your reference number format depends entirely on which DISCO serves your address. Check the bill header for the company name and logo. The format table below helps you verify you've got the right number:
| DISCO | Coverage | Format | Example Prefix |
|---|---|---|---|
| LESCO | Lahore division | 14 digits | 23xxxxxxxxxxxx |
| MEPCO | Southern Punjab | 14 digits | 43xxxxxxxxxxxx or 44xxxxxxxxxxxx |
| FESCO | Faisalabad region | 14 digits | 55xxxxxxxxxxxx |
| IESCO | Islamabad/Rawalpindi | 14 digits | 11xx or 12xx start |
| GEPCO | Gujranwala region | 14 digits | 31xx, 32xx, 33xx start |
| PESCO | KP settled districts | 14 digits | 21xx–23xx start |
| HESCO | Hyderabad/Sindh | 14 digits | 61xxxxxxxxxxxx |
| QESCO | Balochistan | 14 digits | 71xxxxxxxxxxxx |
| SEPCO | Upper Sindh | 14 digits | 66xxxxxxxxxxxx |
| TESCO | Merged tribal KP | 14 digits | 28xxxxxxxxxxxx |
| K-Electric | Karachi | Variable | K-xxxxxxxx or numeric |
Find the Reference Number Without a Physical Bill
Lost your bill? Several ways to get your reference number without it:
1. Call the DISCO helpline (118). Give your complete address — house number, street, area, and city. The helpline can look up your reference number in their system. Have your CNIC ready as they may ask to verify identity.
2. Check your WhatsApp or email. If you've ever shared your bill digitally or received a payment receipt via SMS, the reference number is in those messages. Search "Reference No" or "Ref" in your message history.
3. Look at the electricity meter box. Some DISCO technicians attach a sticker with the reference number to the meter enclosure or the main switch panel. Not universal, but worth checking before calling.
4. Ask your landlord or building manager. In rental properties, the reference number is registered to the property — the landlord almost always has it on file from when the connection was first established.
Distinguish the Reference Number from Other Numbers on the Bill
Pakistan electricity bills have several number fields that look similar at first glance. Here's how to tell them apart:
Reference Number — what you need for online bill checking and payment. 14 digits on WAPDA bills. In the top header section.
Meter Number — the serial number of your physical meter. This is shorter (typically 7–10 digits or alphanumeric) and appears in the meter reading section, usually alongside the previous and current reading figures. The online portal does NOT accept the meter number — only the reference number.
Consumer Number — some DISCOs use this interchangeably with Reference Number. If you see both on your bill and they're different, use the one in the top header, not the one near the meter section.
Application Number — only appears on new connection paperwork, not regular bills. Ignore this one for bill checking purposes.
When Things Go Wrong
The most common mistake is using the meter number (shorter, alphanumeric, near the meter readings) instead of the reference number (14 digits, top of the bill). Make sure you're entering the number from the top header section labeled 'Reference No.' or 'Consumer No.'
Each physical meter has its own reference number. Check the property address printed on each bill to match it to the right property. The reference number is property-specific, not owner-specific — moving out doesn't cancel it.
The prefix table covers the most common cases. Your specific sub-division within a DISCO may have a different prefix. The definitive way to confirm is to call 118 with your address — they can look up the account and confirm the reference number format for your specific location.
Try the LESCO portal at lesco.com.pk — there's sometimes a 'Find Account by Address' option. Alternatively, visit your nearest LESCO subdivision office with your CNIC — they can print your reference number instantly from their system.
Frequently Asked Questions
In most cases, yes — DISCOs use both terms interchangeably on their bills. If your bill shows both fields and they contain different numbers, use the one in the top header section (usually labeled 'Reference No.' or 'Consumer No.') for online bill inquiry.
A phase upgrade typically keeps the same reference number — your account is updated, not replaced. However, your tariff category changes. Confirm with your DISCO subdivision after the upgrade is completed.
No. Reference numbers are unique to each metered connection across the entire DISCO's network. If you enter a reference number and see a different address than yours, you've entered the wrong number.
Call your DISCO's helpline (118) with the complete address. If the flat is in a building with a main meter and sub-meters, the building owner may be the account holder — the individual flat might not have its own DISCO reference number.
The meter has a serial number, not the reference number. Some DISCOs stick a label near the meter with the reference number, but this isn't universal. The paper bill header is the most reliable source.
