When you start your journey into Nepal’s primary share market, you will quickly notice three critical requirements: a Demat account, a Mero Share login, and a CRN (C-ASBA Registration Number). While opening a bank account and setting up Mero Share are straightforward steps, many beginners get stuck right at the final hurdle—entering their CRN during an Initial Public Offering (IPO) application.
Entering the wrong number or confusing your CRN with your 16-digit Demat BOID leads to failed submissions, rejected mandates, and missed investment opportunities. If you want to understand what a CRN number in Nepal is, how to obtain yours without unnecessary branch visits, and how it connects your bank account to your share portfolio, this comprehensive guide covers every detail.
What is a CRN (C-ASBA Registration Number) in Nepal?
CRN stands for C-ASBA Registration Number. It is a unique verification code issued by your bank or financial institution (BFI) that links your bank account directly to the Centralized Applications Supported by Blocked Amount (C-ASBA) system operated by CDS and Clearing Limited (CDSC) under the regulation of the Securities Board of Nepal (SEBON).
Before the introduction of ASBA in Nepal, retail investors had to stand in long physical queues, write paper cheques, and wait months for IPO refund vouchers if shares were not allotted. In 2017, SEBON made the ASBA process mandatory, followed shortly by the centralized digital system known as C-ASBA.
Under the C-ASBA framework:
- Your application money is not immediately deducted from your bank account when you apply for an IPO.
- Instead, the bank blocks (freezes) the required application amount.
- The funds remain safely in your account earning interest until the day of share allotment.
- If you receive an allotment, the exact amount corresponding to the allotted shares is debited, and any remaining balance is automatically unblocked.
Your CRN acts as an authorization token. It proves to the Mero Share system that your bank recognizes your 16-digit BOID, has linked it to an active bank account, and permits CDSC to issue automated hold/debit instructions against that account.
CRN vs. BOID vs. Bank Account Number: Key Differences Explained
One of the most frequent mistakes made by first-time applicants in the Nepali stock market is confusing the various identification numbers required during registration. The table below breaks down the fundamental differences between your BOID, your Bank Account Number, and your CRN.
| Feature | BOID (Demat Number) | Bank Account Number | CRN Number |
|---|---|---|---|
| What It Stands For | Beneficial Owner Identification | Savings / Current Account ID | C-ASBA Registration Number |
| Issued By | Depository Participant (Bank or Broker DP) | Commercial or Development Bank | C-ASBA Certified Bank/BFI |
| Format / Length | Exactly 16 numerical digits | Varies by bank (usually 10 to 18 digits/alphanumeric) | Varies by bank (often 8 to 16 alphanumeric characters or digits) |
| Primary Function | Holds your electronic shares | Holds your deposited money | Authorizes C-ASBA to block funds for primary issues |
| Can It Be Shared? | Yes, public for checking IPO results | Yes, used to receive transfers | Keep confidential; acts as a transaction authorization credential |

How to Get Your CRN Number Online and Offline (Bank Procedures)
Before applying for any public offering, you must obtain your CRN from the specific bank where your funds are held. In Nepal, all licensed commercial banks (Class A) and majority development banks (Class B) offer C-ASBA facilities.
Method 1: Getting Your CRN Number Online via Mobile Banking
Most commercial banks in Nepal (such as Global IME Bank, NIC Asia Bank, Nabil Bank, Sanima Bank, NMB Bank, and others) now allow customers to request and view their CRN directly inside their official mobile banking apps or web portals.
- Log in to your Mobile Banking App using your credentials or biometrics.
- Navigate to the Services, ASBA, or Apply Share / Investment section (the tab name varies slightly depending on your bank’s software).
- Select Register CRN or Apply C-ASBA.
- Select your active savings account and input your 16-digit Demat Account Number (BOID).
- Confirm the personal details displayed on the screen. The name on your bank account and your Demat account must match perfectly.
- Submit the request and enter your transaction PIN or OTP.
- Your CRN will either be generated instantly on the screen or sent via SMS/Email within a few minutes to hours.
Note: If your bank’s app already features an active ASBA module, you can frequently view your existing CRN under the “My CRN” or “C-ASBA Details” tab without re-registering.
Method 2: Getting Your CRN Number Offline (Branch Visit)
If your bank does not offer digital C-ASBA registration, or if your mobile banking details do not sync with your Demat account, visiting your nearest branch remains a dependable method:
- Visit the customer service counter of the bank where you hold your account.
- Ask the representative for a C-ASBA Registration Form.
- Fill in your basic information: Full Name, Account Number, Contact Details, and your 16-digit Demat BOID.
- Attach a photocopy of your Citizenship Certificate and your Demat Confirmation Slip (printed from Mero Share or provided by your DP).
- Submit the completed form. The bank officer will verify your signatures and record your Demat number in their C-ASBA system.
- You will be handed an acknowledgment slip containing your registered CRN Number.
How to Link and Use Your CRN Number in Mero Share
Once you have your active CRN in hand, you are ready to submit an application on the Mero Share portal. You do not need to register your CRN permanently in your account settings; instead, you enter it each time you apply for an issue to authorize the fund hold.
Here is the exact step-by-step process:
- Open your browser or mobile app and log in using your Depository Participant (DP), Username, and Password. If you do not have an active account yet, refer to our walkthrough on how to register for Mero Share online.
- On the main dashboard, click on My ASBA from the navigation menu.
- Under the Apply for Issue tab, you will see all currently open public offerings (IPOs, FPOs, Rights Issues, or Debentures).
- Locate the company you want to apply for and click the green Apply button.
- Select your Bank from the dropdown list. Your account number and branch will load automatically if previously linked.
- Enter the number of units (Applied Kitta) you wish to purchase.
- Locate the field labeled CRN Number and enter your bank-issued CRN accurately.
- Check the disclaimer box agreeing to the terms and click Submit.
- Enter your 4-digit Transaction PIN to finalize the request.

How to Find or Recover a Forgotten CRN Number
It is common for investors who apply for shares intermittently to misplace their CRN. If an IPO window is about to close and you cannot locate your number, use these fast recovery channels:
1. Check Your Mobile Banking App
Log in to your banking application and head directly to the ASBA / Investment menu. Most apps maintain a profile section titled View CRN or Registered C-ASBA that reveals your number instantly without requiring customer support.
2. Search Your Email and SMS History
Search your inbox and text messages for keywords such as “CRN”, “CASBA”, “C-ASBA”, or the name of your bank. Banks routinely send an automated SMS or registration confirmation email containing your CRN the moment it is generated.
3. Check Your Physical C-ASBA Acknowledgment Slip
If you registered at a physical branch, look for the counter-signed receipt or deposit paper provided by the customer representative. The CRN is usually hand-written or stamped near the top right corner.
4. Call Your Bank’s Helpline
Call your bank’s official customer support number. After answering a few standard identity verification questions (such as your full name, date of birth, mother’s maiden name, and account balance), the representative can look up your registered C-ASBA record and provide your CRN.
Troubleshooting Common CRN Issues During IPO Applications
Even with a valid CRN, applicants occasionally encounter technical rejections on Mero Share. Here are the most common error alerts and how to resolve them:
1. “Invalid CRN” Error
This is the most widespread error message on Mero Share. It occurs when:
- You selected Bank A from the dropdown menu, but entered the CRN provided by Bank B.
- You accidentally typed an extra space before or after the number when copying and pasting.
- You confused alphanumeric characters (for example, typing the letter “O” instead of the number zero “0”, or “I” instead of “1”).
Solution: Double-check that the bank selected in Mero Share matches the bank that issued your CRN, and type the characters manually without leading or trailing spaces.
2. “Customer Details Mismatch / Demat Mismatch”
If your bank’s records have a slight difference in your name spelling, citizenship number, or BOID compared to your Demat profile, the centralized C-ASBA server will reject the submission.
Solution: Ensure your Know Your Customer (KYC) details are updated identically at both your bank branch and your Depository Participant.
3. “Insufficient Balance / Amount Blocking Failed”
Although your CRN may be correct, the transaction will fail if your available bank balance does not cover the full cost of the shares plus any applicable C-ASBA service fee. While several banks in Nepal process C-ASBA free of charge, some charge a nominal processing fee (up to Rs. 5 as regulated by SEBON).
Solution: Verify that your savings account balance has sufficient unrestricted funds to cover the total applied kitta amount plus any nominal service charge before clicking submit.
4. “CRN Not Activated”
If you submitted an online or offline C-ASBA request just minutes before applying for an IPO, the bank backend may still be syncing your registration with CDSC’s servers.
Solution: Wait 15 to 30 minutes and try again. If the issue persists during working hours, contact your bank branch’s ASBA department to ensure they have authorized your record in the centralized system.
Frequently Asked Questions (FAQs)
Is the CRN number the same as my bank account number?
No. Your bank account number is used for deposits, withdrawals, and standard money transfers. Your CRN is a specialized authorization identifier generated exclusively for the C-ASBA system to manage IPO application holds.
Can I get my CRN number through mobile banking without visiting the branch?
Yes. The majority of commercial and development banks in Nepal offer online CRN registration directly through their mobile banking applications or internet banking dashboards under the ASBA / Share Investment tab.
Why does Mero Share display an ‘Invalid CRN’ error during IPO submission?
The error usually happens if there is a typo, an unintended space, a mismatch between the bank selected in the dropdown and the bank that issued the CRN, or if your bank has not yet finalized activating your C-ASBA registration on the central CDSC network.
Do I need a different CRN if I have multiple bank accounts?
Yes. A CRN is tied to a specific bank account. If you maintain accounts at two different banks (for example, NIC Asia and Nabil Bank) and both are linked to your Demat account, each bank will generate its own distinct CRN. You must use the corresponding CRN for whichever bank you select during the application.
How long does it take for a bank to activate a CRN number?
When applying through mobile banking apps, many banks activate the CRN instantly. For in-person branch visits or manual form submissions, it typically takes between 1 hour and 1 working day depending on the branch’s operational workflow.
Does obtaining or using a CRN cost money?
Generating or registering a CRN is completely free across all banks in Nepal. When applying for an IPO, some BFIs provide C-ASBA service free of cost, while others may deduct a small processing fee (capped at Rs. 5 per application by SEBON regulations). Always check your specific bank’s tariff schedule.
Final Thoughts
Your CRN is an indispensable piece of your investment toolkit in Nepal. It bridges the gap between your hard-earned money in the bank and your securities portfolio in CDSC. By generating your CRN in advance and ensuring your bank details align with your Demat account, you avoid last-minute server bottlenecks and ensure your IPO applications are processed without interruption.
