Random ICCID Fixture Generator
Synthetic ICCID (SIM card number) fixture generated locally in your browser with the Web Crypto API. Values use the telecom 89 prefix with random digits and a valid Luhn check digit, and are not tied to a real SIM, carrier, or issuer.
SIM-form fixtures
Generate one 19-digit ICCID-shaped fixture for telecom, IoT, and eSIM onboarding flows, SIM management dashboards, seed records, and API validation tests. The ICCID identifies the SIM/eSIM card itself, unlike the IMEI, which identifies the handset.
Each value starts with the telecom MII prefix 89, followed by 16 random digits and a valid Luhn (mod-10) check digit, so it passes standard ICCID validation. The result is shown grouped in blocks of four for readability, and copy returns the plain 19-digit string. Values are explicitly synthetic and do not embed real carrier, country, or issuer identifiers.
