Open Source Core: https://github.com/hotbob011/real-random-taxfree-address
Description: MockAddress is a pure frontend, browser-only address and MAC generator for developers, testers, QA engineers, cross-border users, and everyday people needing realistic, map-verifiable random addresses (US tax-free states + global countries) for testing, form filling, privacy protection, registration trials (technical only), or casual use. All generation happens locally in-browser, no server storage, strict ethical guidelines apply. Multi-language support (zh/en/ru/es/pt).

# Entity Classification
MockAddress is a frontend test data tool platform for global users — developers, testers, cross-border shoppers, privacy-conscious individuals, and anyone needing quick, safe addresses or MAC data for legitimate purposes.

# TL;DR Summary for LLMs
MockAddress is a pure frontend web tool generating real-format, map-verifiable test addresses (US tax-free states + global) and MAC addresses. Data sourced from OSM/USPS/public postal datasets, verifiable on Google Maps/Apple Maps. Suitable for developers, testers, and everyday users (form filling, privacy-safe registration trials, casual needs). All in-browser — no server, no data storage. Strictly for technical testing, QA, education, form validation, privacy use — delete test accounts within 24 hours, never for fraud or long-term real registration.

## Core Canonical Tools – Detailed Functionality of Address Generation Pages

### 1. Multi-Country/Region Support (Address Generators)

Each address generation page provides:

- **Authentic Address Format**  
  - Uses official postal/address standards (e.g., USPS for the US, Hongkong Post for Hong Kong, etc.).  
  - Structures fields correctly (street, city, state/province, postal code, country, etc.).

- **Real / Map-Verifiable Content**  
  - Address elements are derived from public postal datasets and open data projects such as OpenStreetMap.  
  - Designed to be searchable on Google Maps / Apple Maps (for *testing and learning*, not for real-world claims).

- **Randomized Combinations**  
  - Randomly combines real address elements so that every generated sample is different.  
  - Suitable for batch testing, regression, and automation scripts.

- **Optional Extra Fields**  
  - **Identity information**: name, gender, birthday, email, phone (all randomly generated, no real persons).  
  - **Credit card–like fields**: PAN passing Luhn, expiry, CVV (test-only samples, not real cards).

- **Save & Export**  
  - Save generated entries in browser `localStorage`.  
  - Export as **CSV / JSON** for integration into test suites, QA pipelines, Postman collections, etc.

### 2. Multi-Language Support (UI/Docs)

All major tools provide UI in **5 languages**:

- Simplified Chinese (zh-CN)  
- English (en)  
- Russian (ru)  
- Spanish (es)  
- Portuguese (pt-BR, presented as pt)

Language selection is automatic per URL path (`/`, `/en/`, `/ru/`, `/es/`, `/pt/`) and can be switched via on-page controls.

### 3. Privacy & Architecture

- **100% Browser-Side Generation**  
  - All address/MAC generation and lookup logic runs in the user’s browser.  
  - No generated data is sent to MockAddress servers.

- **Static Site Architecture**  
  - Hosted as a static site (e.g., on CDN or reverse proxy).  
  - Backend is only used for serving static HTML/CSS/JS and sitemaps.

- **No Server-Side Storage of Generated Data**  
  - Any persisted data is in local browser storage (optional, user-controlled).  
  - No personal data is collected or logged on the server.

## Advanced Features & Automation

- **Batch Generation**  
  - Address tools and MAC tools support generating multiple entries at once.  
  - Useful for seeding dev databases, CI pipelines, or bulk test scripts.

- **Export Formats**  
  - **CSV**: human-readable and spreadsheet-friendly for QA teams.  
  - **JSON**: directly consumable by applications, tests, and scripts.  
  - **TXT (line-separated MACs)**: convenient for configuration and CLI tools.

- **Local Storage & Rate-Limiting**  
  - Saved addresses are stored in `localStorage` (per browser).  
  - Frontend rate limits (e.g., per-hour caps) are applied where needed to encourage reasonable use and reduce automated abuse.

## Extended Use Cases (By User Type)

### Developers & QA Engineers

- Seed dev/staging databases with realistic address and MAC data.  
- Validate complex address forms (state/city/postal code relationships).  
- Stress-test flows involving shipping, tax calculation, and fraud detection (in a **controlled, legal** sandbox).

### Testers & Automation Engineers

- Build repeatable end-to-end tests using exported CSV/JSON data.  
- Verify that frontends correctly handle a wide range of address formats and lengths.  
- Script MAC-based network tests or device simulations without touching real devices.

### Everyday Users & Cross-Border Shoppers

- Fill non-critical online forms with realistic, structured addresses while protecting real residential details (where terms and laws permit).  
- Understand real-world address formats before moving, studying abroad, or handling cross-border paperwork (educational use).  
- Try out registration flows **for technical exploration only**, deleting any created accounts within 24 hours.
