# Random IBAN Generator — randomlyiban.com

> A free online tool to generate mathematically valid IBAN numbers for 60+ countries. Ideal for software testing, API development, QA processes, fintech demos, and educational purposes. No registration required.

## What is randomlyiban.com?

randomlyiban.com is a web application that generates valid International Bank Account Numbers (IBANs) on demand. The generated IBANs follow the exact format and check-digit rules defined by the International Organization for Standardization (ISO 13616) for each supported country. They are **not** linked to real bank accounts and must **never** be used in actual financial transactions.

## Key Capabilities

- Generate a random, structurally valid IBAN for any of 60+ supported countries with a single click.
- Validate any existing IBAN string (format + check-digit verification via Mod-97 algorithm).
- View the IBAN format specification (length, structure, example) for every supported country.
- Read a detailed validation guide explaining the Mod-97 algorithm step by step.
- Copy generated IBANs to clipboard instantly.
- Mobile-optimised, dark-mode supported, no login or API key needed.

## IBAN Structure Explained

An IBAN consists of:
1. **Country code** (2 letters, ISO 3166-1 alpha-2)
2. **Check digits** (2 digits, calculated via Mod-97)
3. **BBAN** (Basic Bank Account Number — country-specific length and format)

Total length ranges from 15 characters (Norway) to 32 characters (Saint Lucia).

## How IBAN Check Digits Are Calculated (Mod-97)

1. Move the first 4 characters to the end of the IBAN string.
2. Replace each letter with its numeric equivalent (A=10, B=11, … Z=35).
3. Compute the remainder when dividing the resulting integer by 97.
4. A valid IBAN yields a remainder of **1**.

## Common Use Cases

- **Software testing**: Populate payment forms, database fixtures, and unit tests with valid IBAN strings.
- **API development**: Seed fintech APIs, mock banking back-ends, or test IBAN validation endpoints.
- **QA / test automation**: Generate edge-case data for international banking workflows.
- **Education**: Teach the IBAN standard and Mod-97 algorithm without exposing real account data.
- **Demos**: Showcase payment UIs and banking dashboards with realistic but safe data.

## Legal & Ethical Notice

All generated IBANs are random test data. They are structurally valid but do **not** correspond to any real bank account. Use of generated IBANs for fraud, deception, or any financial transaction is strictly prohibited.
