What the 10-Digit Customer ID Is
The short answer first: the 10-digit customer ID is an account identifier that some bank and mobile-wallet payment flows use to attach a SEPCO bill to a payment. It is not what the official PITC bill lookup portal asks for — that portal only accepts the 14-digit reference number. So if your goal is to see this month's billed amount on screen, you need the 14 digits, and the full lookup walkthrough is in the reference number bill check guide. If your goal is to pay through a banking or wallet app, the 10-digit customer ID is often exactly the number the app wants.
Both numbers are printed in the top section of every paper bill, near your name and address, and both stay the same every month because they identify the connection rather than a single bill. The easiest way to tell them apart on a crowded bill layout is simply to count digits: fourteen means reference number, ten means customer ID. Anything with letters mixed in is likely the meter serial, which is a third thing entirely and works nowhere online.
One-line rule: 14 digits to check the bill, 10 digits for some payment apps. When a screen asks for a number, count what it expects before you type.
Customer ID vs Reference Number: The Differences
People run into trouble because the two numbers look similar at a glance — both are printed close together, both are digits-only, and both belong to the same account. Here is how they actually compare:
| Feature | 10-digit customer ID | 14-digit reference number |
|---|---|---|
| Length | 10 digits | 14 digits |
| Printed where | Top section of the bill | Top section of the bill, near name and address |
| Changes monthly? | No — fixed per connection | No — fixed per connection |
| Works on the PITC bill lookup portal | No | Yes — the only number it accepts |
| Works in bank / wallet payment flows | Yes, on some channels | Yes, on channels that ask for it; bank and agent staff can also pull the bill from it |
| What it encodes | Your account in the billing system | Batch, sub-division office, and individual account |

Which Channels Accept Which Number
Think of the two numbers as keys to two different doors:
- Bill lookup (viewing the bill): the official PITC bill portal — the national billing system reachable from SEPCO's official website — accepts only the 14-digit reference number. There is no customer ID field, and no CNIC, name, or meter number field either.
- Bill payment: SEPCO bills can be paid at bank counters such as NBP, at Pakistan Post offices, through 1LINK ATMs, in bank mobile and internet banking apps, and via JazzCash or Easypaisa. Some of these app flows ask for the 10-digit customer ID when you add SEPCO as a biller; others ask for the reference number. The label on the entry field and the number of boxes it expects tell you which one to use.
- In-person help: bank and agent-shop staff can usually pull up a bill from the 14-digit reference number, and your SEPCO sub-division office can find the account from either number — or from your name and address if you have neither.
If an app rejects your number, the most common cause is simply that you fed it the wrong one of the two. The payment methods guide compares every channel in detail.
Step-by-Step: Using the Customer ID
- Find the number. Take any bill for the connection — this month's, last year's, or a photo on your phone — and locate the clean 10-digit number in the top section. Count the digits to confirm.
- Open your payment app. In your bank's mobile app, JazzCash, or Easypaisa, go to bill payments and choose electricity, then SEPCO from the company list.
- Check what the field asks for. If the screen expects 10 digits, enter the customer ID; if it expects 14, enter the reference number instead. Type digits only — no spaces or dashes.
- Confirm the account details. Before paying, the app shows the account holder's name and the billed amount. Verify the name matches your bill so you are not paying someone else's account from a typo.
- Pay and keep the receipt. Save the transaction receipt or screenshot until the payment shows in next month's bill history.
To simply see the bill first — amount, due date, units — use the 14-digit number on the portal as described in the reference number check guide, then save a copy via the duplicate bill guide. Our homepage bill helper can also validate a 14-digit number's format instantly before you head to the portal.
Only Have One of the Two Numbers?
If you only have the customer ID: you can still pay through channels that accept 10 digits, but you cannot run the portal lookup. To recover the 14-digit reference number, check any old bill or bill photo for the connection — the number never changes. A neighbour's bill reveals your area's batch and sub-division digits, the local SEPCO sub-division office can look the account up by name and address, and the 118 helpline can guide you to the right office. All routes are covered in where to find your SEPCO reference number.
If you only have the reference number: you are in the stronger position. The portal lookup works, bank and agent staff can pull the bill from it, and once the bill is on screen you can save a PDF copy — which itself shows the customer ID in its top section, recovering the other number for free.
If you have neither: do not try shortcuts like CNIC or name lookups — the portal accepts neither. Go straight to the recovery routes above.
Frequently Asked Questions
Can I check my SEPCO bill on the PITC portal with the 10-digit customer ID?
No. The PITC bill lookup portal only accepts the 14-digit reference number. The 10-digit customer ID is a payment-side identifier that some bank and wallet apps accept when you add an electricity bill for payment.
Is the SEPCO customer ID the same as the meter number?
No. The meter number is the serial printed on the physical meter and often includes letters. The customer ID is a clean 10-digit account identifier printed in the top section of the bill. Neither one works on the PITC bill lookup portal — only the 14-digit reference number does.
Does the customer ID change every month?
No. Like the 14-digit reference number, the customer ID identifies your connection rather than a single bill, so the same 10 digits appear on every monthly bill for that meter.
My banking app rejects my 14-digit reference number. What should I enter?
Check what the app's SEPCO bill screen asks for. Some payment flows expect the 10-digit customer ID instead of the 14-digit reference number, and a 14-digit entry will fail validation there. Copy the 10-digit number from the top section of a printed bill and try again.
I only have the customer ID. How do I get my reference number?
Any old bill for the connection shows the 14-digit reference number in its top section — a photo of a bill works too. If no bill survives, your local SEPCO sub-division office can look the account up by name and address, and the 118 helpline can point you to the right office.
