Bankak Explained: How Sudan's Biggest Banking App Works (2026)

If you bank in Sudan, there's a good chance you already have this app on your phone. Bankak, run by Bank of Khartoum, is the closest thing Sudan has to a universal digital-money app — millions of users, and usage has climbed sharply since the war began, as branches became harder to reach and phones became the more reliable option. Here's what it actually does, and what to watch for.

What Bankak does

Transfers between your own accounts, to other Bank of Khartoum customers, and to accounts at other banks (via card/account number through the interbank EBS Sudan service).
Transfers to any mobile-money-type recipient, not just other BOK customers.
Bill and merchant payments — utilities and other billers are payable directly in-app.
It works whether or not you have a smooth internet connection in your area, which matters given the state of connectivity in parts of the country during the conflict.

Why a banking app became infrastructure

In most countries a bank's app is a convenience — somewhere to check a balance without queueing. In Sudan since 2023 it has become something closer to essential infrastructure, and understanding why explains a lot about how people actually manage money here now.

When branches close, are damaged, or sit in areas that are unsafe to reach, the physical banking network stops being the default way to move money. A phone doesn't have that problem in the same way. Reporting on Sudan's wartime economy has consistently described digital payment apps as a lifeline for households cut off from cash and branches — and Bankak, already the largest before the war, absorbed a sharp jump in new activations as a result.

That has a practical consequence worth naming: for a lot of Sudanese households the app is now the primary account, not a secondary view of one. That raises the stakes on the security and access questions below, because losing access to the app increasingly means losing practical access to your money, even though the money itself is still safely held by the bank.

Limits — check these before you rely on a number

Bank of Khartoum sets daily and per-transaction transfer ceilings on Bankak, and these have been raised more than once as the app's role grew during the war. Any specific limit quoted anywhere — including a figure you've seen elsewhere — should be treated as a snapshot, not a fact: .

Two practical points that outlast whatever the current number is:

Per-transaction and daily limits are different ceilings. A transfer can be refused for exceeding the single-transaction cap even when you're well inside your daily allowance — splitting a large payment across several transfers within the daily limit is often the intended path.
Plan large payments around the limit, not against it. If you need to move an amount above the daily ceiling — a business payment, a property or vehicle purchase, a large family transfer — that's a branch or direct-bank-instruction conversation, not something to solve by making many rapid transfers, which can look like structuring and get an account frozen for review.

Is it safe?

Bankak is a product of a CBOS-licensed commercial bank, not an unregulated app — a meaningfully different risk profile from an unlicensed lending or investment app (the distinction our licensed-lender guide walks through in full). The bank is supervised, your deposit sits in a real supervised institution, and the app is a channel into it rather than a financial product in its own right.

That means the realistic risks aren't "will the bank vanish" — they're access and fraud risks, which are the ones you personally control:

Only ever install it from the official Google Play or Apple App Store listing. Never from a link sent by message, and never from a third-party APK mirror site — those are a standard vector for banking-trojan lookalikes that copy the real interface.
Nobody legitimate will ask for your OTP. A one-time code exists to prove you are the one authorising something, typed by you into the app. A caller asking you to read one out is, without exception, attempting theft — no matter how convincingly they present themselves as bank staff, and no matter what urgent-sounding problem they claim to be resolving.
Treat unexpected "help" as hostile. The common pattern is: a caller claims your account is compromised or a transfer is stuck, creates urgency, then asks for a code or asks you to move money to a "safe" account. Real banks don't resolve fraud by asking you to send money anywhere.
Protect the phone number, not just the app. Because codes arrive by SMS, control of your SIM is control of your account. If your number suddenly loses service for no clear reason, treat that as a possible SIM-swap attempt and contact both your mobile operator and the bank immediately rather than waiting to see if service returns.
Lock the phone itself. A device PIN or biometric lock is the last barrier between a lost handset and everything the app can do.

If your phone is lost, stolen, or you're displaced

This deserves its own answer in a Sudanese context, because "just visit your branch" may not be available:

Contact Bank of Khartoum immediately to freeze app access. Do this before worrying about the handset itself — the account matters more than the phone.
Know your alternate contact route in advance. Note the bank's official phone contact somewhere that isn't only inside the phone you might lose. Confirm it from the bank's own official channels rather than a search result, since fake "bank support" numbers are a known scam surface.
If you've moved cities or crossed a border, your account doesn't move with you but your access method may need to change — confirm directly with the bank what's possible from where you now are, including whether SMS codes will reach a foreign number, which is the single most common thing that silently breaks access after relocating.

Keeping records

Because prices and the exchange rate move quickly in Sudan, in-app transaction history is worth more than it would be in a stable-currency market. Export or screenshot records of significant transfers as you make them — particularly anything business-related, anything you may need to prove for a family arrangement, and anything you'd want dated if a dispute comes up later. Our business-registration guide covers why formal record-keeping matters once you're trading formally.

How receiving money works

If someone abroad is sending you money, a transfer that lands in your BOK account is accessible through Bankak the moment it clears — see our receiving money from abroad guide for how the transfer itself gets there.

Frequently asked questions

Is Bankak the same as a mobile-money wallet? Not quite, and the difference matters. In East Africa, M-Pesa is a telco wallet — the balance sits with a mobile operator, not in a bank account. Bankak is a bank's own app tied to a real bank account, so the account protections and supervision that apply to Bank of Khartoum apply to the money you hold in it. Practically, that also means it plugs into the normal banking system — interbank transfers, and receiving international payments — in ways a pure telco wallet typically doesn't.

What if I don't bank with Bank of Khartoum? Other CBOS-licensed banks run their own apps — . Bankak is simply the largest and most talked-about, not the only option. The evaluation questions are the same whichever bank you use: is the bank CBOS-licensed, what are the current transfer limits, and how do you regain access if you lose the phone?

Can I use Bankak to receive money from abroad directly? Generally yes, if the sender's transfer method deposits into a linked bank account — confirm with your specific bank or transfer operator that Bank of Khartoum is a supported receiving bank before relying on it. Our guide to receiving money from abroad covers which channels actually reach Sudan, and the full sending guide covers it from the sender's side.

Does the money in the app earn anything? That depends on the account type behind it, not the app. Sudanese banks operate on Islamic principles, so any return is a profit share rather than interest — see Islamic banking basics for how that actually works, and ask your bank what applies to your specific account.

What happens to my money if the app stops working? The app is a channel, not the account. If the app is down, your money is still held by the bank — the problem is access, not loss. That's the practical argument for knowing at least one alternate route to your bank (a phone number, a reachable branch) before you need it.

Is it safe to use over public or shared Wi-Fi? Prefer mobile data for banking where you can. If you must use shared Wi-Fi, avoid it entirely for logging in or authorising transfers, and never on a device that isn't yours — a shared or borrowed phone can retain session access after you hand it back.
