Mero Share Terms Explained: BOID, CRN, C-ASBA, DP, EDIS & WACC

Mero Share terms are the short forms and numbers a Nepali investor meets after opening a demat account. BOID, CRN, C-ASBA, DP, EDIS, and WACC each handle a part of applying for an IPO, holding shares, and selling them. The login screen asks for your DP and BOID. My ASBA asks for your CRN. My Purchase Source records your WACC.

This post explains each term in simple terms: the full form, who issues it, what number or format it represents, and where it appears in Mero Share. You'll also find the 2026 regulations that changed the paperwork, including requiring a national ID for new demat accounts. Once these terms are no longer just a mishmash of letters, opening an account and applying for a share issue takes just a few minutes.

What Is the Mero Share Portal?

The login screen at the CDSC portal greets you with a DP dropdown, a username box and a password field. Behind that screen sits Mero Share, the online platform CDS and Clearing Limited (CDSC) runs so investors in Nepal can apply for IPOs, FPOs and right shares, view holdings, check application results and approve share deliveries after selling. You log in through the official Mero Share portal.

The portal reads your holdings from the depository record behind your demat account, so every Mero Share term on this page links back to the same system.

Your DP issues your Mero Share account, and the login screen asks for three things: your DP, your username and your password. The username is usually your BOID. Everything after login, from the dashboard to My ASBA to My Purchase Source, uses the terms below.

BOID: The 16-Digit Number That Names Your Demat Account

BOID stands for Beneficiary Owner Identification Number. It is the 16-digit number CDSC assigns to your demat account the day it opens. Your DP gives it to you, and each demat account gets its own BOID, so your shares land in the right account.

You type your BOID into three places. The Mero Share login screen takes it as your username. The IPO application form records it against your application. The official result portal asks for it when you check whether the lottery allotted you shares.

Find your BOID in four quick steps:

1. Go to meroshare.cdsc.com.np and log in.
2. Open the menu on the left.
3. Choose My Details.
4. Read the 16-digit number below your DP name.

CDSC reports more than 8 million beneficiary accounts in its depository, and each one carries its own BOID. Keep the number with your login details, because each future share transaction in Nepal references it.

New demat accounts also ask for your National ID number. CDSC made the NID mandatory from Shrawan 1, 2083, which falls on July 17, 2026, for account opening and for KYC updates on existing accounts.

CRN: The C-ASBA Registration Number Your Bank Issues

CRN stands for C-ASBA Registration Number. Your bank issues it after you register for C-ASBA, and it links your bank account to your demat account for IPO applications. You enter this number in My ASBA when you apply for an issue, so the bank knows which account to block.

The letters carry history. In older share application forms, CRN stood for Company Registration Number, which confused investors. In today's C-ASBA system, your bank generates the C-ASBA Registration Number, and Mero Share or CDSC does not produce it. Getting it takes one short registration:

1. Pick your bank. It must offer C-ASBA, and most commercial banks in Nepal do.
2. Fill the C-ASBA registration form, at a branch or online where the bank allows it.
3. Enter your BOID, bank account number and personal details.
4. Wait for verification, then note the CRN the bank issues.

Keep the number private, like your PIN. A wrong or unregistered CRN is the most common reason an IPO application gets rejected, and the error shows up only after the issue closes.

C-ASBA: How Your IPO Money Gets Blocked, Not Debited

C-ASBA stands for Centralized Application Supported by Blocked Amount. It is the system that blocks your application money in your bank account when you apply for an IPO, FPO or right share through Mero Share. The money stays in your account until allotment.

SEBON made C-ASBA mandatory for public issues from Falgun 11, 2074, which falls on February 23, 2018. CDSC runs the central platform, and 43 banks were registered in it as of August 2026.

The system removes refunds from the process. There is no cheque to wait for and no bank queue, because the money sits in your own account the whole time. Your bank may charge a small application fee for the service, and the amount varies by bank.

DP: The Institution Behind Your Demat Account

DP stands for Depository Participant. A DP is a licensed institution that opens and manages demat accounts on CDSC's behalf. Commercial banks, merchant bankers and stockbrokers all act as DPs, and CDSC lists 124 of them as of August 2026.

Your DP does three jobs for you. It verifies your documents and opens the demat account, it hands you the BOID, and it issues your Mero Share login. On the login screen, the first dropdown asks you to pick your DP before you enter your username.

Choose a DP you can reach easily, since renewal and document updates run through it. Most people open their demat account with the bank where they already keep money, which keeps the C-ASBA registration and the CRN in the same place.

EDIS: The Delivery Slip That Settles Every Share Sale

EDIS stands for Electronic Delivery Instruction Slip. After you sell shares through your broker, you approve the delivery in Mero Share under My EDIS so the shares move from your demat account to the buyer. Without that approval, the sale cannot settle.

The approval happens the day after your trade, so the sale finishes on the T+2 settlement cycle. Approve it in three steps:

1. Log in to Mero Share and open My EDIS.
2. Select the delivery tied to your sale and check the quantity.
3. Confirm, and the shares leave your demat account for the buyer.

EDIS is easy to confuse with an IPO application, but the two are unrelated. My ASBA handles applications for new shares. My EDIS handles the delivery of shares you already sold. Skip the second one and your trade fails, and you may face a penalty from your broker.

WACC: The Average Price MeroShare Tracks as Your Cost Basis

WACC stands for Weighted Average Cost of Capital. Mero Share records it under My Purchase Source as the average price you paid for each scrip. The figure you confirm there becomes your cost basis for capital gains tax when you sell.

The average weights each purchase by its size. Buy 100 shares at Rs 400 and 50 more at Rs 300, and your total outlay is Rs 55,000 across 150 shares, so the weighted average is Rs 366.67 per share. The simple average of the two prices, Rs 350, would understate your real cost. Confirm the weighted average the tax office will use with the SajiloX WACC calculator.

Corporate actions change the number. Bonus shares add quantity at no cost, which pulls the average down. Right shares add both quantity and cost, which blends the average with the right price. Keep the purchase source updated after each credit, so the figure you confirm matches your records.

BOID vs CRN vs DP: Numbers That Are Easy to Mix Up

The three identifiers answer different questions, and mixing them up causes the most application errors.

Think of it as three questions. BOID tells the system who you are. CRN tells the bank which account to block. DP tells CDSC which institution manages your account.

More Mero Share Terms on the Dashboard

The menus use a few more names that stay unexplained until they matter. This table covers the ones you will meet most often.

Once you know the terms, the workflow reads clearly. BOID and DP get you into Mero Share, CRN and C-ASBA let you apply, EDIS closes a sale, and WACC sits at the center of your tax cost. Price a full trade with the SajiloX Share Calculator, commission and taxes included. Register your bank account with C-ASBA before an issue opens, because the registration itself takes a day at many banks. If a login, an expiry or a missing demat record blocks you, the Mero Share login fixes guide and the Mero Share vs demat account breakdown walk through each case. Demat paperwork asks for your date of birth and address in the Bikram Sambat calendar, so confirm the dates with the Nepali Date Converter and your age with the Nepali Age Calculator before you fill the form.
