AKUH paybill not working?
What to do when an M-PESA payment to AKUH (paybill 638000) has not gone through, or has gone through but the service has not activated.
Three quick checks first
Before you reach for support lines, run these. Most paybill complaints clear up at this stage.
- Did you receive an M-PESA confirmation SMS? If yes, with a 10-character code like
RG7HX9BC2K, the payment went through and the issue is on the recipient side. If no, the payment failed or is still pending. Check your M-PESA balance to confirm whether you were debited at all. - Was the paybill number 638000? One wrong digit routes the funds to a different business. Look at the M-PESA SMS and confirm the recipient name shown matches Aga Khan University Hospital, Nairobi.
- Was the account number in the right format? Your AKUH patient invoice number.
Common errors and what they mean
Paybill not found
M-PESA did not recognise the number you keyed in. The official AKUH paybill is 638000. Verify each digit. If the number is correct, Safaricom may be having a temporary outage. Wait fifteen minutes and try again, or check @Safaricom_Care for status.
Insufficient balance
You do not have enough M-PESA balance for the amount plus the fee. Top up via an agent, a bank-to-M-PESA transfer, or use Fuliza if it is enabled. The M-PESA daily transaction cap is KES 500,000 for fully-verified accounts; the per-transaction cap is KES 250,000.
Account number error
The account number did not match the format AKUH expects. Your AKUH patient invoice number. Note: A common cause is using the policy number when the system expected the member ID, or vice versa. They are usually different fields.
Money taken but service not activated
This is the most common pain. Your policy or hospital bill is still flagged as unpaid, or your coverage has not reactivated. First try: Insurance and hospital reconciliations can take 24 to 48 hours. Check with the operator self-service portal or call the contact line before assuming the payment failed.
Still stuck after 30 minutes? Phone the operator's billing or customer care line. Provide the M-PESA code, your policy or patient number, and the amount.
Transaction reversed
Safaricom auto-reverses when the recipient system rejects the payment, usually because of a wrong account format. The funds return to your M-PESA wallet within 30 minutes. No action needed except retrying with the correct details.
PIN locked
Three wrong PIN attempts locks M-PESA. Dial *234#, choose My Account, then Reset PIN. Use your registered ID number and answer the security questions. If the reset fails, walk into a Safaricom Care centre with your national ID; they can unlock on the spot.
Calling Safaricom vs calling AKUH
The two lines handle different problems. Calling the wrong one wastes time.
Call Safaricom on 100 (Safaricom line) or 0722 002 100 (other lines) for: PIN locked, transaction errors, requesting a reversal, M-PESA outage suspicion.
Call AKUH for: payment received but service not activated, account or IUC mismatch, or any billing question about your specific account with them. Find their contacts at hospitals.aku.edu/nairobi
If the paybill itself looks wrong
If repeated payments to 638000 keep failing in a way that suggests the paybill itself is incorrect, deactivated, or fraudulent, flag it for our review. We re-verify against the operator and update or pull the listing within 24 hours.
Report this paybillReversing the transaction
If AKUH cannot resolve and the funds need to come back, Safaricom can attempt a reversal within seven days of the transaction.
- Dial
*234#from your Safaricom line. - Choose My Account, then Reversal.
- Key in the M-PESA transaction code (10 characters, in your SMS).
- Confirm. Safaricom contacts AKUH and requests release of the funds.
- Resolution typically takes two to seven business days. Successful reversals refund your wallet; failed reversals leave the funds where they are.
Reversals only work if AKUH agrees to release the funds. They often do for clear errors but may charge a small admin fee. After seven days, Safaricom can no longer process the reversal.
