AddressMock: US Address Generator & Autofill

Generate matching US test addresses, including tax-free states, and autofill forms. Everything runs locally in your browser.

AddressMock is a US test address generator for developers, QA engineers, designers, demos, and form testing. Generate a complete sample identity and US address without leaving the current tab, then autofill common address fields on the active page. Key features: Covers all 50 US states plus Washington, D.C. Includes an all-region mode and a dedicated tax-free state mode for Alaska, Delaware, Montana, New Hampshire, and Oregon. Choose a state, city, and gender, or keep each option random. Keeps city, state code, ZIP code, and phone area code aligned using bundled reference data. Autofills common name, email, phone, street, address line 2, city, state, ZIP, and country fields. Fills forms inside iframes and open Shadow DOM components, which most checkout pages rely on. Billing and shipping groups are matched separately instead of overwriting each other. Keyboard shortcuts: Alt+Shift+A generates a new address and fills the page; Alt+Shift+F refills with the current one after a form reset or a multi-step checkout. Right-click menu: fill just the field under the cursor, fill the whole form, or generate a new address and fill — without opening the popup. Per-field reroll: when a site rejects a street, email, phone, name, or ZIP as duplicate, swap that one field while city and state stay consistent. Uses negative matching rules to avoid search, promo code, coupon, note, and comment fields. Copy individual fields or the full address bundle. Export the current record as JSON or CSV. Save recent records locally for reuse, removal, or clearing. Supports English and Simplified Chinese, with light and dark themes. Opens a generated address in Google Maps for format reference. Privacy and permissions: Address generation happens locally in the browser. Generated names, addresses, phone numbers, and emails are not uploaded to AddressMock servers. No account is required. The extension does not read cookies, passwords, or browsing history. The active page is accessed only after the user triggers a fill — from the popup button, a keyboard shortcut, or the context menu. The activeTab permission is temporary and limited to that page. History and preferences stay in chrome.storage.local. Anonymous usage statistics are optional and can be switched off in settings. Designed for registration forms, checkout QA, CRM demos, UI prototypes, automated testing, and documentation samples. Important: generated data is for development, testing, demos, and format reference. Individual street numbers are not guaranteed to exist or receive mail. Do not use the extension for fraud, fake transactions, policy evasion, or unlawful activity.
