How to Find Your Consumer Number on Any Bill (CA, BP, K and CAN Explained) in 2026

Your consumer number is the unique ID that ties your connection to its billing. The catch is that no two utilities call it the same thing. Electricity boards print it as a CA number, piped gas companies use a BP number, Rajasthan and Delhi bills show a K number, and Telangana uses CAN. This guide explains each one, shows where it sits on your bill, and walks through how to find yours even when you do not have a bill in hand.

Why the Same Number Has Four Different Names

Every electricity board, gas distributor and water utility assigns each connection one permanent identifier. That ID does the same job everywhere: it links your meter to your billing record, your payment history and any complaint you raise. What differs is only the name on the bill.

That single fact trips up most people at payment time. You open an app, it asks for a "BP number", and your bill says "CA No". They are the same kind of thing, just named by different utilities. The table below maps the labels you are most likely to meet.

What Your Provider Calls Your Consumer Number

A note before you go hunting: the consumer number and the bill number are not the same. The bill number changes every cycle. Your consumer number never does.

CA Number in Your Electricity Bill

On most electricity bills, the ID you need is the CA number, short for Contract Account Number. A few boards expand it as Consumer Account Number, but the function is identical. Adani Electricity, Tata Power, Mahavitaran (MSEDCL) and both Bihar boards (NBPDCL and SBPDCL) all label it "CA No". It usually runs 9 to 12 digits and varies in format from one state to the next.

You will find it printed near the top of the bill, close to your name and address. In Bihar bills it sometimes appears in Hindi as खाता संख्या (account number) on urban bills and उपभोक्ता संख्या (consumer number) on rural ones. If you pay through an app, the CA number is the field the system uses to fetch your outstanding amount.

BP Number in Your Gas Bill

Piped natural gas works on a different label. Companies such as IGL, Mahanagar Gas, HP and GAIL identify you by a BP number, which stands for Business Partner number. It is a 10-digit code unique to your connection, and you cannot pay a piped gas bill or log into a gas portal without it. An IGL BP number, for example, looks like 1000023313.

Look for it in the header of your gas bill, usually boxed at the top-left or top-right. If you have lost the bill, the fastest route is to log into the gas company's website or app with your registered mobile number, or call customer care and verify your identity. Unlike water and some electricity portals, most gas distributors do not let you look up a BP number by name alone, so keep an old bill or SMS receipt handy.

K Number in Rajasthan and Delhi Bills

If your bill shows a K No., you are almost certainly in Rajasthan or paying a Delhi water bill. Rajasthan's DISCOMs (JVVNL in Jaipur, JDVVNL in Jodhpur, AVVNL in Ajmer) and the Delhi Jal Board both use the K number as the consumer identifier. There is no widely published full form for it, so treat it simply as the account code printed on the bill.

It appears in the account details box. To download a Rajasthan electricity bill, you enter the K number on the JVVNL or JDVVNL portal. For Delhi water, the same number (shown as K No.) pulls up your bill on the DJB site. If you have misplaced the bill, the Rajasthan Energy portal lets you search your K number using your registered details, and DJB customer care can retrieve it against your address.

Can Number in Telangana

Across Telangana, the identifier is the CAN, or Consumer Account Number. The Hyderabad water board (HMWSSB) and the state electricity utility (TSSPDCL) both use it. It is a unique 9-digit number, usually printed and highlighted at the top of the bill.

What makes CAN easier than most is the lookup. On the HMWSSB website, under Services you will find "Search Your Account Number (CAN)", where you can find your number using your name, house number and registered mobile. That makes it one of the few utilities where you can recover your ID without any old bill at all.

How to Find Your Consumer Number: Step by Step

Whatever your utility calls the number, the process to find it is the same. Follow these steps in order and stop at the one that works.

1. Pick up your latest bill. Look at the top section, near your name and address. Find the label that matches your utility: CA No, BP number, K No, CAN, or Account Number.
2. Read off the number. It is usually 9 to 13 digits. Copy it exactly, including any leading zeros, and ignore the bill number, which is a separate code that changes each month.
3. No bill handy? Log in online. Open your provider's website or app and sign in with your registered mobile number. Your consumer number sits in the account or profile section.
4. Still stuck? Use the search tool or call. Boards like HMWSSB (CAN), the Rajasthan Energy portal (K number) and UPPCL ("Know Your Account Number") let you search by your details. If none of that works, call customer care and verify your identity to get the number read out.

Once you have it, save it in your phone or to your NoBroker account so you never repeat this search.

How to Find Your Consumer Number Without the Bill

Lost the paper bill? You have several ways to recover the number, roughly in order of speed:

1. Check an old payment confirmation. The SMS or email receipt from any past payment usually carries the consumer number.
2. Log into your provider's app or website with your registered mobile number. The number sits in your profile or account summary.
3. Use the provider's "search" tool where one exists. HMWSSB (CAN), the Rajasthan Energy portal (K number) and UPPCL ("Know Your Account Number") all support this.
4. Check a saved bill on a payment app. If you have paid through NoBroker before, your number is stored against the connection.
5. Call customer care. After identity verification, the helpline can read out your number.

Can You Find It by Name?

Sometimes, but not always, and it depends entirely on the utility. HMWSSB lets you search a CAN by name and house number. Many state electricity portals require your registered mobile number rather than just a name, because a name alone is not unique enough to safely return account data. Gas distributors are the strictest: for a BP number, expect to verify by mobile or to call customer care. Treat name search as a convenience some boards offer, not a guarantee.

Found Your Number? Here Is the Easy Way to Pay

Once you have the right ID, you do not need to juggle a different portal for each bill. On NoBroker, you enter the number once, the app auto-fetches your electricity, gas or water bill, and pays it through BBPS-backed channels. It stores the number, sends a reminder before the due date, and keeps every receipt in one place, so next month you are not searching for the number again.

One Number, Every Bill: The Takeaway

Once you know that CA, BP, K and CAN are just different names for the same thing, finding your consumer number stops being a monthly hassle. Locate it once on your bill or through your provider's search tool, note it down, and you are set for every payment after.

Better still, hand the remembering to NoBroker. Enter your number a single time and the app auto-fetches your electricity, gas and water bills, pays them through secure BBPS channels, reminds you before each due date, and files every receipt in one place. No more digging for a CA number at 11pm on the due date. Pay your first bill on NoBroker and let your consumer number work for you instead of against you.
