Let me clear up the terms first, then the exact steps.
The two IDs people confuse:
CHN (Clearing House Number): your unique investor ID in the Nigerian capital market. It should be the same across all platforms and brokers.
CSCS Account Number: assigned by each broker for that specific relationship. It's normal to have different CSCS numbers with different brokers, but they should all link back to the same CHN.
If your numbers show differently, you likely need to confirm them and possibly merge duplicate CHNs.
Step 1: Retrieve your details.
Dial *7270# on your phone (works well on MTN, expanding to others) to check your CHN without internet. Or check inside your broker apps, or log into the official CSCS portal at https://t.co/Lmspy5PjlG
Step 2: Contact your stockbroker.
Ask them to confirm your CHN and the CSCS account number linked to your holdings. They can usually fix minor mismatches on their end.
Step 3: If you have multiple different CHNs.
CSCS allows merging. You'll need a formal letter of authority to CSCS stating which CHN to keep as primary, a valid ID, proof of address, and payment of ₦3,225 to Central Securities Clearing System, 2036325225, First Bank. Keep the receipt.
Submit documents and receipt to [email protected] or through your broker. Processing takes time, so follow up politely.
Step 4: For the unclaimed dividends.
Search your name on the SEC portal at https://t.co/731nztTAbG. Note the Registrar for each dividend, then download and submit the e-Dividend Mandate Form for that registrar with your passport photo, valid ID and bank details.
Important:
Use official channels only. Never send money or personal details to anyone in your DMs.
If the shares belong to a late relative, you'll need extra documents like letters of administration or probate.
For help: CSCS on 0700 2255 2727 or [email protected]. But start with your broker, they handle most updates.
Once you have one harmonized CHN with linked CSCS details, all future dividends and claims become much smoother.
