Pay PostBank via Airtel Money
How to pay PostBank (M-PESA paybill 200900) from your Airtel Money wallet, and whether it works out cheaper than paying via M-PESA.
Paying PostBank from Airtel Money
- Open Airtel Money. Dial
*222#from your Airtel line, or open the Airtel Money app if you have it installed. - Select "Pay Bill" or "Make Payment". The exact menu wording depends on your SIM toolkit version. Look for the option that asks for a business / paybill number.
- Enter the PostBank paybill: 200900. This is the same number used on M-PESA. Don't use a different one. There isn't a separate Airtel Money paybill for PostBank.
- Enter your account number / reference. Use your PostBank account number.
- Enter the amount. Confirm with your Airtel Money PIN.
- Wait for the confirmation SMS. Airtel Money confirms first; PostBank confirms within 1-15 minutes once funds settle.

Airtel Money tariff figures are approximate. Airtel does not publish brackets as transparently as Safaricom. Verify on airtelkenya.com before relying on the exact number for large transactions.
Should you use Airtel Money or M-PESA for this payment?
Use whichever wallet already has the funds. Moving money between wallets to save a few shillings on the paybill fee rarely pays off, since the cross-network send fee usually eats the saving.
Airtel Money is usually cheaper at most amounts. Airtel competes by undercutting Safaricom on tariff. For routine bill payments under KES 5,000, the saving is roughly KES 5 to 15 per transaction.
M-PESA still has wider merchant trust. For very large payments above KES 50,000, some users prefer M-PESA because the recipient is more familiar with M-PESA confirmations. Functionally, both networks work equally well thanks to interoperability.
If the payment doesn't go through
- Confirm your Airtel Money SMS shows the payment was sent to paybill 200900. If the number is wrong, request a reversal via Airtel customer care (100).
- Check the recipient. Has PostBank processed similar interoperability payments before? Most paybills have. If you are the first to test cross-network on a niche paybill, expect occasional 24 to 48-hour delays.
- If PostBank doesn't reflect the payment after 1 hour, contact their customer service with the Airtel Money transaction code. They can manually reconcile.
- As a last resort, use the same paybill from M-PESA. Cross-network has rare settlement delays that do not affect the same-network route.
