Prefilling the MoMo Number at Checkout: +12% Conversion (2026)

The verdict in three sentences

Asking the customer to choose their operator at checkout is a needless step: the number prefix already says it. By detecting the operator automatically — 77/78 Orange, 70/76 Free in Senegal, 07/05 Orange/MTN in Côte d'Ivoire — and pre-selecting the right channel, you gain +12% conversion. Bonus: operator errors drop from 9% to 2%, easing your customer support just as much.

The prefix mapping by country

Detection relies on a reliable prefix table, maintained per country. Here is the 2026 reference mapping for the main markets.

Wave, meanwhile, works on top of all operators: it stays offered as a universal option regardless of prefix, simplifying the choice even further.

The measured gain, before / after

Pre-selection does not only win conversion: it reduces failed payments and support tickets. Here is the quantified impact (2026 order of magnitude).

Fewer operator errors means fewer failed payments, fewer support calls and more customers who go all the way — a triple benefit for a modest build.

Mini case study

Cheikh, who runs an electronics store in Abidjan, handled 60 support tickets/month tied to operator errors, average basket 25,000 FCFA. After enabling prefix detection (07 → Orange, 05 → MTN), errors fall from 9% to 2%. On 500 orders/month, that means 35 recovered failed payments = 875,000 FCFA of saved revenue, and -5 support tickets per 100 sales, drastically cutting team time.

FAQ

How much does operator detection improve conversion?

By about +12% in relative conversion, because it removes a choice step and cuts errors. On a store at a 2.5% baseline, you land around 2.8%.

What happens if a prefix changes or is ported?

We keep the prefix table updated and always leave Wave as a universal option. If in doubt, the customer can manually correct the operator in one tap.

Does detection work across several countries?

Yes. We configure prefix tables per country (Senegal, Côte d'Ivoire, Mali, Burkina...), making multi-country checkout effortless for the buyer.

How many payment errors does it avoid?

Failed payments tied to the wrong operator drop from about 6% to 2.5%, directly recovering sales and cutting support tickets by several per 100 orders.

Is it compatible with Wave and Orange Money at once?

Yes. We pre-select the detected operator channel while keeping Wave visible in parallel, leaving the customer the final choice without forcing a blind selection step.
