What the parts are called in Switzerland
A Swiss IBAN has 21 characters: CH, two check digits, the 5-digit bank clearing number (IID, formerly BC number) and a 12-character account part that may contain letters.
Swiss banks build the account part themselves, and some include letters or branch numbers. The calculator pads your input with zeros on the left; compare the result with your bank’s documents. The same format is used in Liechtenstein (LI).
The check digits of CH93 0076 2011 6238 5295 7
- Move the first four characters to the end: 00762011623852957CH93
- Replace each letter by a number (A = 10, B = 11 … Z = 35): 00762011623852957121793
- Divide that number by 97. The remainder is 1; a valid IBAN always leaves 1.
- To calculate the check digits instead, put 00 in their place: the remainder is 5, and 98 − 5 = 93.
