The single most important thing is your reference number (sometimes called consumer number), a 14-digit code printed at the top of any previous paper bill. If you've never had a paper bill, it's also stamped on the electricity meter itself or available from your DISCO's customer service on request.

Some portals also accept a shorter account or consumer ID depending on the distributor — LESCO, MEPCO, FESCO, GEPCO, IESCO, PESCO, HESCO, SEPCO, QESCO, TESCO, and K-Electric all format this slightly differently, so if one site rejects your number, double-check you're using the format that specific DISCO expects rather than assuming the number itself is wrong.

Keep your CNIC handy too — a few DISCO portals ask for it as a secondary check, particularly for commercial connections or when requesting a duplicate bill.

Each DISCO runs its own bill-inquiry page — search "[your DISCO name] bill check" and you'll land on the official portal where entering your reference number pulls up the current bill and, on most sites, the last several months for comparison. This is the most detailed option since it shows unit-by-unit consumption history alongside the amount due.

If typing your DISCO's name and hunting for the right link every time gets old, a consolidated checker is the faster path. bijlibillcheck.pk lets you enter your reference number once and pulls the current bill regardless of which DISCO issued it, which is handy if you're checking bills for family members or properties served by different distributors.

SMS and WhatsApp options exist too on several networks — sending your reference number to the DISCO's designated short code returns the amount due by text, which is useful when you have a weak data connection but a working SMS signal. Availability varies by distributor, so check your specific DISCO's customer-service page for the current short code.

Open the checker (your DISCO's site or a consolidated tool), enter your 14-digit reference number exactly as printed — no spaces, and include any leading zeros. Submit, and the current bill should load within a few seconds showing units consumed, amount payable, and the due date.

From there, most portals let you download or view a PDF version of the bill, which is what you'd normally present at a bank counter or use for a duplicate-bill request. Save this copy to your phone or email it to yourself so you have a record even if the site is slow to load later.

If the portal times out or shows a server error — common during peak evening hours when traffic to DISCO sites spikes — wait a few minutes and retry, or fall back to the SMS method for at least the amount and due date while you wait for the site to recover.

"Reference number not found" almost always means either a digit was mistyped or you're on the wrong DISCO's portal — reference numbers aren't interchangeable between distributors. Re-check the number against your last paper bill or the meter itself before assuming there's an account problem.

If the bill shown looks unusually high, check the units-consumed figure against your last few months before contacting your DISCO — a sudden jump often reflects an estimated (rather than actual) meter reading, in which case you can request a correction once an actual reading is taken.

For a duplicate or reprinted bill — needed for bank submissions or record-keeping — most DISCO portals offer a "duplicate bill" option once your reference number is entered, generating a fresh PDF identical to the original.
