# IESCO bill check online: reference number, customer ID and duplicate bill (2026) Source: Searchable (https://searchable.pk/guides/utilities/iesco-bill-check-online-reference-number-customer-id-and-duplicate-bill-2026) Type: Guide Author: Searchable Editorial Published: 16 Sept 2026 Updated: 14 Oct 2026 Retrieved: 31 Oct 2026 > How to see, download and pay a IESCO electricity bill online in under a minute, what the two numbers on the bill mean, and what to do when the amount looks wrong. IESCO, the Islamabad Electric Supply Company, is the government distribution company for Islamabad, Rawalpindi, Attock, Jhelum and Chakwal, from Attock to Jhelum and from the Indus to the Neelum. Its bills are checked, downloaded and paid online through the same system every WAPDA-descended company uses, so once you have done it once you can do it for a relative anywhere in the country. Looking for a different company? Every electricity and gas company's duplicate bill is on our [duplicate bill page](/guides/utilities/k-electric-bill-check-online#duplicate-bills). ## What you need before you start Any old IESCO bill, paper or a photo of one. Two numbers on it work: - **Reference number**: 14 digits, printed at the top left of the bill. A single letter, **U** or **R**, is printed at the end of it; the online form asks for that letter separately. - **Customer ID**: 10 digits, printed just above the reference number on newer bills. The reference number usually stays the same for years, so an old bill normally still works. **The exception: AMI (smart) meter consumers in the Rawalpindi City and Rawalpindi Cantt circles.** IESCO has reorganised their billing batches, and the batch is the first two digits of the reference number (in 07 14316 1111800, the batch is 07). Under IESCO's notice, old batches 1 and 2 became **17**, 3 and 4 became **18**, 5 and 6 **19**, 7 and 8 **20**, 9 and 10 **21**, 11 and 12 **22**, 13, 14 and 15 **23**, and 24 to 28 became **31**. If you are in one of those circles and an old reference number returns "no record found", use the reference number on your latest bill, or get the new one on [iesco.com.pk](https://www.iesco.com.pk) with the customer ID printed on your bill, or from your SDO or revenue office. If you have no bill at all, the reference number is also on the meter installation card and on the sticker some meter readers leave; failing that, IESCO's helpline (118 from any phone) can read it back to you against the CNIC the connection is registered to. ## Check the bill online, step by step 1. Open https://bill.pitc.com.pk/iescobill in any browser. 2. Choose **Reference No** (or **Customer ID** if that is the number you have). 3. Type the 14 digits with no spaces. Pick **U** or **R** from the small box beside it to match the letter on your bill; the default is U. 4. Press the search button. The current month's bill opens as an image of the printed bill: units used, the tariff slabs applied, taxes and duties, the **due date**, the amount **payable within due date** and the higher amount **payable after due date**. 5. To keep a copy, use the print or download option on the page, or your browser's print to PDF. Banks and offices accept this duplicate bill as they would the paper one. The page shows the latest bill only. Older bills are not kept on the public portal; for a history, ask at the sub-division office with the reference number, or use the company app, which keeps recent months. IESCO also has the IESCO Smart app and the Power Smart app on Google Play, which shows the same bill once you add your reference number. ## Reading the amount Two figures matter. **Payable within due date** is what you pay on time. **Payable after due date** includes the late payment surcharge; pay that amount once the due date has passed, and expect the surcharge to appear on the next bill if you paid the lower figure late. Bills arrive roughly a month after the reading date, and the due date is usually about ten days after the bill is issued, so a bill you first see online may already be close to due. If the units look wrong, compare the **present reading** printed on the bill with what the meter shows now. A reading far above the meter means an estimated or mistaken bill; that is a helpline or sub-division complaint, and the correction comes as a revised bill, not a refund. ## Paying it Any bank app or internet banking that offers bill payment (the 1Link network), JazzCash and Easypaisa, bank branches, post offices and NADRA e-Sahulat outlets all take IESCO bills against the reference number. Online payments post to the account within a day or two; keep the transaction ID until the next bill shows the payment. ## Why the bill jumps Residential tariff is slab-based, and a household that stays under 200 units for six consecutive months is billed as **protected** at much lower rates. Crossing 200 units once moves the whole bill to the unprotected slabs, and it takes six months under 200 to get back. Our [electricity bill calculator](/tools/utilities/electricity-bill-calculator) shows the slab-by-slab arithmetic for any number of units on the current NEPRA tariff, and the [IESCO page](/electricity/iesco) has the company's contacts and the other companies' portals. ## Complaints and the helpline Dial **118** for power failures and billing complaints, or text **8118**. The Power Information Technology Company (PITC) runs the complaint system for all the distribution companies, so the same numbers work from any network. For a wrong reading, take the bill and a photo of the meter to the sub-division office named on the bill; for detection bills (theft or tampering allegations) you have a right to a hearing, and NEPRA's consumer complaint cell is the next step if the company does not resolve it. ## Frequently asked questions **Can I check the bill by SMS?** No. The distribution companies do not send bills by SMS; the online portal, the company app and the paper bill are the channels. Any site or number promising SMS bills is a third party. **Is there a fee for the online duplicate bill?** No. The portal is free and needs no login. **The portal says "no record found".** Check the letter (U or R) and count the digits: 14 for the reference number, 10 for the customer ID. New connections take a billing cycle to appear. **Why does my bill show arrears?** An unpaid previous month, a late payment surcharge, or an adjustment (a fuel price adjustment, a quarterly tariff adjustment) approved by NEPRA and applied to everyone in that month. Adjustments are printed as separate lines on the bill. **Can I change the name on the bill?** Yes, at the sub-division office, with proof of ownership or tenancy and the CNIC; the reference number stays the same. Correction, 13 October 2026: this guide said an IESCO reference number never changes. IESCO has changed the billing batch numbers, and so the first two digits of the reference number, for AMI-meter consumers in its Rawalpindi City and Rawalpindi Cantt circles, according to its public notice. The section on finding your reference number now explains the change. ## Frequently asked questions **How do I check my IESCO bill online?** Open https://bill.pitc.com.pk/iescobill, choose Reference No, type the 14-digit reference number from any old bill and the U or R letter printed after it, and search. The current bill opens as a printable image. **Where is the reference number on the bill?** At the top left of the printed bill: 14 digits followed by the letter U or R. The 10-digit customer ID is printed just above it on newer bills and also works on the portal. **What is the IESCO helpline?** 118 from any phone for complaints and power failures, or SMS 8118. The same numbers work for every distribution company. ## Sources - IESCO web bill portal (PITC): https://bill.pitc.com.pk/iescobill - Islamabad Electric Supply Company: official site (IESCO): https://www.iesco.com.pk - Consumer service manual and complaint procedure (NEPRA): https://nepra.org.pk/ - IESCO notice: billing batch numbers of AMI-meter consumers in Rawalpindi City and Cantt circles reorganised (September 2026) (IESCO): https://iesco.com.pk/storage/e-kacheries/September2026/525EUew0s5hFV7gGbheR.jpeg How to cite: "IESCO bill check online: reference number, customer ID and duplicate bill (2026)", Searchable, 14 Oct 2026, https://searchable.pk/guides/utilities/iesco-bill-check-online-reference-number-customer-id-and-duplicate-bill-2026
