IBAN format · SV

El Salvador IBAN format: 28 characters.

El Salvador IBANs have 28 characters: the country code SV, two check digits and a 24-character BBAN, the national account number, laid out as 4!a20!n.

Parts of a El Salvador IBAN and their positions
Positions	Part	In the example
1–2	Country code	SV
3–4	Check digits	62
5–8	Bank code	CENR
9–28	Account	00000000000000700025

The BBAN, segment by segment

The registry writes the BBAN in SWIFT notation: n is a digit, a an upper-case letter, c a letter or digit, and the ! means a fixed length. 4!a20!n reads:

El Salvador IBAN example

SV62 CENR 0000 0000 0000 0070 0025 is the sample the SWIFT IBAN Registry publishes for El Salvador: a well-formed IBAN for showing the format, not a real account. Written electronically it has no spaces (SV62CENR00000000000000700025); on paper it is printed in groups of four.

Its check digits, worked through with ISO 7064 mod 97-10:

Move the country code and check digits to the end
CENR00000000000000700025SV62
Replace each letter with two digits (A = 10 … Z = 35)
C = 12, E = 14, N = 23, R = 27, S = 28, V = 31
1214232700000000000000700025283162
Divide that number by 97 and keep the remainder
Remainder 1. A valid IBAN always leaves 1, so the check digits are right.
Where the check digits come from
Put 00 in their place (SV00…), repeat steps 1–3: remainder 36. The check digits are 98 − 36 = 62.

SEPA

El Salvador is not in the Single Euro Payments Area, so SEPA credit transfers and direct debits don’t reach SV IBANs.

What the format can and can’t tell you

Valid means the structure and check digits are right — not that the account exists or can receive payments.
National check digits inside the BBAN (e.g. the French RIB key, or the Spanish, Belgian and Italian CIN digits) are not verified.
Bank and branch codes are read from their positions; they are not looked up in a bank directory.
