CSCS Account in Nigeria: How to Open One, Find Your CHN and Check Your Shares

Every share you own on the Nigerian Exchange lives in one place: your CSCS account. Not in your broker's app. Not with the company whose shares you bought. At the Central Securities Clearing System (CSCS), Nigeria's central securities depository.

Yet most Nigerian investors have never looked inside it. Many don't know their CHN, the number that identifies everything they own. Some have two or three CHNs scattered across old brokers and forgotten public offers, with money attached to each one.

This guide covers the entire system: what CSCS is, how to open an account, how to find a lost CHN, how to log in and check your shares, and how to pull everything you own into one view.

What Is CSCS?

The Central Securities Clearing System Plc is the central depository, clearing and settlement house for the Nigerian capital market. It was incorporated in 1992 and began operations in 1997, replacing paper share certificates with electronic records.

When you buy shares through any stockbroker, the trade settles at CSCS and the shares are credited to your account there. When you sell, CSCS debits them. Your broker is the gate; CSCS is the vault.

What Is a CHN (Clearing House Number)?

Your Clearing House Number is your unique investor identity in the Nigerian capital market. Think of it the way you think of your BVN in banking: brokers come and go, but your CHN identifies you, and every share you own settles against it.

• It is issued when a stockbroker opens your CSCS account during onboarding.
• It stays the same for life, no matter how many brokers you use.
• It appears on your contract notes (the confirmation slips brokers send after each trade) and on your CSCS statements.
• You need it for e-dividend registration, share transfers, and claiming unclaimed dividends.

How to Open a CSCS Account

Here is the part that confuses most people: you cannot open a CSCS account directly with CSCS. Accounts are opened through licensed stockbrokers. When you complete onboarding with a broker, the broker creates your CSCS account and your CHN behind the scenes.

How to Find Your CHN

Lost or never knew your CHN? Work down this list:

1. Ask your stockbroker. Fastest route. Check your broker app's profile section, your contract notes, or email their support with your account name.
2. Check old documents. Contract notes, CSCS statements and public offer allotment letters usually carry the CHN.
3. Visit a CSCS office for a global search. If you no longer know which broker holds your shares (common with inherited shares or shares from the 2004 to 2008 boom), go to a CSCS office in Lagos or Abuja with a valid ID. A global search finds every shareholding linked to your name across the entire market, including holdings you may have forgotten. Biometric capture is part of the process, which is what makes the search authoritative.

How to Check Your Shares (3 Ways)

1. Through your stockbroker

Your broker's app or periodic statements show the holdings they manage for you. This is the everyday option, with one limit: a broker only shows you what sits under their account with you, not shares you hold through other brokers or old offers.

2. Through the CSCS online portfolio service

CSCS offers an Online Portfolio Management service that lets you view your stock portfolio directly at the depository, independent of any broker. You can register on the CSCS website at cscs.ng, and access the investor portal once your details are verified. Because this is the depository's own record, it reflects everything settled under your CHN.

3. At a CSCS office: statement of stock position

For a formal record (useful for loans, probate, or reconciling old holdings), request a statement of stock position at a CSCS office with a valid ID. Biometric verification is compulsory for this, which protects you: nobody else can pull your records.

Multiple CHNs? How Consolidation Works

Two decades of public offers, broker switches and name variations (maiden vs married names, missing middle names) mean many investors' shares are split across several CHNs. CSCS's biometric system exists partly for this: it supports reconciliation and consolidation of accounts across CHNs and stockbroking firms, so your full position sits under one identity.

The practical route: visit CSCS with your ID for the global search, identify every CHN linked to you, then work with your current broker to consolidate. If any of those holdings have been paying dividends you never received, our unclaimed dividends guide shows how to recover them, and it is often a meaningful amount.

CSCS and Your Dividends

Your CSCS account determines what you own; dividend payments are handled by each company's registrar, paid to the bank account in your e-dividend mandate. The two systems connect through your CHN. If your CSCS records and registrar records disagree (a name spelling, an old bank account), dividends quietly fail. Keeping both aligned is the single best piece of admin a Nigerian investor can do. Upcoming payment dates for every declared dividend are on our NGX dividend calendar.

Frequently Asked Questions

Is a CSCS account free?

Opening one costs you nothing directly; it is created by your broker during onboarding. Brokers may charge their own account or transaction fees, and some CSCS investor services carry service charges. Confirm current charges with your broker or CSCS before paying anything.

Can I have shares without knowing it?

Yes, and it is remarkably common: shares bought in the 2004 to 2008 boom, employer share schemes, or inherited holdings. The CSCS global search is the definitive way to find out.

Does my CHN change if I switch brokers?

No. Your CHN is permanent. A new broker links their trading account to your existing CHN, or you can transfer holdings between brokers under the same CHN.

What happens to a deceased person's CSCS account?

The shares remain safely held at CSCS. Transfer to heirs goes through the registrars and CSCS with letters of administration or probate documents. Start with the deceased's broker or any registrar involved, and be patient: it is paperwork-heavy but very doable.

Is CSCS the same as the NGX?

No. The NGX (Nigerian Exchange) is the marketplace where shares trade. CSCS is the depository where ownership records live and trades settle. You interact with the NGX through prices and orders; you interact with CSCS through your CHN and holdings.
