Yes — you can use one CSCS/CHN across different brokerage apps, including Afriinvest and Invest Niger. Here’s the clear explanation:
First, What Are CSCS and CHN?
CSCS — Central Securities Clearing System Plc
This is where your shares are actually stored in Nigeria.
CHN (Clearing House Number)
This is your unique investor ID in CSCS. Think of it like your bank account number for shares.
Can You Use One CSCS/CHN for Multiple Brokers?
Yes. You can use one CHN for:
Afriinvest Securities
Invest Niger
Any other Nigerian broker
Because:
Your shares belong to YOU, not the broker
Brokers only help you buy/sell
CSCS is the central custodian
How It Works
You can:
Open account with Afriinvest → Use your existing CHN
Open account with Invest Niger → Use same CHN
Buy shares from both apps → Shares go into one CSCS account
Example:
Broker
Shares Bought
Where Stored
Afriinvest
GTCO
Same CSCS
Invest Niger
Dangote Cement
Same CSCS
Another broker
Zenith Bank
Same CSCS
All appear in one CSCS account.
Important Things to Know
Benefits of Using One CHN
All your shares in one place
Easier dividend tracking
Easier portfolio management
More secure ownership
When You Might Have Multiple CHNs
You may end up with multiple CHNs if:
You opened accounts with different brokers without linking existing CHN
Some brokers create new CHN automatically
But you can merge them later.
My Professional Advice (Best Practice)
Since you’re building wealth gradually (and you’re already learning investing seriously):
Use ONE CHN for all brokers
This keeps things clean and professional.
