IBAN Structure Sudan

Last reviewed: · Source: ISO 13616 / SWIFT IBAN Registry

Sudan's IBAN has 18 characters in the format SDkk BBBB BBBB BBBB BB. After the country code SD and the check digits come a 2-digit bank code and the 12-digit account number. Sudan is not a SEPA participant. The currency is the Sudanese pound (SDG). For international payments, routing details, fees and timing depend on the banks, currency and route; check them in advance with your bank. Payments to Sudan are subject to heightened compliance checks at banks — expect additional queries and longer processing times.

Frequently asked questions

How do I check the length of an IBAN from Sudan?
Remove spaces and count 18 characters. The first two characters are SD; the remaining positions follow SDkk BBBB BBBB BBBB BB. A different length is formally invalid for this country format.
What do the check digits in a Sudan IBAN mean?
The two check digits are calculated from the complete IBAN using ISO 7064 MOD-97. They help detect format and transcription errors. A passing checksum does not confirm that an account exists or identify its account holder.
What should I do when an IBAN is formally invalid?
Check the country code, character count, letters and digits, and the check digits. Compare the entry with your bank records or ask the bank for the correct IBAN. This checker validates structure and checksum; it does not verify account ownership or payment approval.
