Method of Calculating Check Digits
Preliminary step: Create an artificial IBAN composed of the country code followed by ‘00’ as a check digit and the BBAN Example: BG00AAAA12311012345678 Step 1: Move the first four characters (the country code and the check digits) of the IBAN to the right of the number. Example: BG00AAАА12311012345678 becomes AAАА12311012345678BG00. Step 2: Convert the letters into numerics in accordance with the alpha to numeric conversion table:
A = 10 G = 16 M = 22 S = 28 Y = 34
B = 11 H = 17 N = 23 T = 29 Z = 35
C = 12 I = 18 O = 24 U = 30
D = 13 J = 19 P = 25 V = 31
E = 14 K = 20 Q = 26 W = 32
F = 15 L = 21 R = 27 X = 33
Example: AAAA12311012345678BG00 becomes 1010101012311012345678111600. Step 3: Calculate the check digits using modulo 97:

• The result of step 2 is divided by 97.
• The remainder of the division is substracted from 98.
• If the result is one digit, then insert a leading zero
  Example: The remainder of the division of 1010101012311012345678111600 by 97 is 65. 98 – 65 = 33. The check digit for this IBAN is 33. IBAN= BG33AAAA12311012345678.

to Article 8, paragraph 1
Method of Validating the Check Digits
Preliminary step: If the IBAN is in paper format, convert to electronic format by deleting all spaces. Example: IBAN such as BG33 AAAA 1231 1012 3456 78 becomes BG33AAAA12311012345678. Step1: Move the first four characters (the country code and the check digits) of the IBAN to the right of the number. Example: BG33AAAA12311012345678 becomes AAAA12311012345678BG33. Step 2: Convert the letters into numerics in accordance with the alpha to numeric conversion table specified in Appendix No 2 :
Example: AAAA12311012345678BG33 becomes 1010101012311012345678111633. Step 3: Apply modulo 97. For the check digits to be correct, the remainder after calculating the modulus 97 must be 1. Example: The remainder of the division of 1010101012311012345678111633 by 97 is 1.
