You made me look it up. On the IBAN Web site, it appears that there is
an overall format for IBAN, but how it's formatted is unique to each
country's banking system.
Given that BIC is 8 digits with three optional digits to identify the
branch if the bank uses it, no, the BIC is not contained in the IBAN.
However, the IBAN has something within to identify the bank.
There were two Web pages explaining the IBAN structure, one for Germany
and the other for United Kingdom. Other countries didn't have more
detailed Web pages.
In Germany, pre-IBAN, banks were identified by BLZ. I think this is
comparable to a routing code on an American check. This is 8 digits,
followed by a 10 digit account number.
To create the IBAN, it appears that Germany prepended its two-letter
country code DE and the two digit modulo 97 checksum. It's wacky that
checksum digits are internal digits rather than appended at the end.
In the UK, IBAN is two-letter country code, two-digit checksum, the
first four BIC characters, six-character bank and branch code, 8
character account code.
In an earlier followup, I said IBAN was required to use SWIFT. I should
have said BIC was required to use SWIFT.
I've noticed that both the SWIFT site and IBAN site have validators, for
BIC and IBAN respectively. I think if I ever need to make an
international wire, it would behoove me to validate codes. Transactions
are reversible with invalid codes and account numbers, but there's a
second fee and a significant delay when the transaction is reversed.
The validators re-calculate checksums, don't actually check that the
account numbers are valid or belong to the person I believe it would
belong to.8 character account code.
