Placeholder Address Block Generator
Hand-writing fake addresses for mockups is slow, and reusing your own is worse. This generator assembles between 1 and 20 address blocks from fixed pools — ten first names, ten last names, and per-country street and city lists — in three formats. US blocks follow name, street number and street, then city, two-letter state, and ZIP; UK blocks use name, house number and street, city, and a generated postcode; the generic format drops region-specific codes for internationalized mockups. Every block is randomly assembled, so nothing corresponds to a real person, and the numeric parts are random digits rather than valid postal codes — a mail carrier could not deliver to them, which is exactly what you want in test data. Note what the blocks do not include: there is no country line and no UK county, so add those manually if your form has the field. Paste the output into Figma frames, checkout flows, or database seed files as-is.
How to use
- Choose your options above
- Click Generate
- Copy your result
Detailed instructions
- Set the Number of Addresses field to how many blocks you need, between 1 and 20.
- Select a Country Style from the dropdown — choose US for ZIP codes or UK for postcodes.
- Click the generate button to instantly produce a formatted batch of placeholder address blocks.
- Review the output and click generate again if you want a fresh set of randomized addresses.
- Copy the addresses individually or all at once and paste them into your mockup, prototype, or test database.
Use Cases
- •Populating a Figma e-commerce checkout prototype with 5 realistic US address blocks
- •Seeding a PostgreSQL test database with fake customer shipping records before a QA sprint
- •Filling CRM demo accounts with UK-format addresses ahead of a localization review
- •Testing address input validation in a React form without touching real user data
- •Generating address blocks for a Storybook component showing an order history list
Tips
- →Generate the maximum batch of 20 when seeding a database — repeated generations give you a varied, non-repetitive dataset.
- →For multi-country products, generate separate US and UK batches and place them side by side to check layout consistency across regional formats.
- →When testing address validation forms, look for edge cases in the output like long street names or two-line addresses and use those specifically to stress-test your UI.
- →Paste address blocks into a monospace font layer first to verify column alignment before switching to your design typeface.
- →If your prototype needs named recipients, pair this generator with a name generator and assign one name per address block for fully believable user records.
- →For invoice or receipt mockups, use a count of one and regenerate a few times to find an address with a realistic length that fits your layout's text box.
FAQ
are these addresses safe to show in public demos and screenshots
Yes. Names combine from small fixed pools, and street numbers, ZIPs, and postcodes are random digits, so blocks do not reference real people and are not deliverable. A random combination could superficially resemble a real address, so treat them strictly as fictional test data — never mail to one or present one as a real location.
what is the difference between the US, UK, and generic formats
US blocks end in city, two-letter state, and a five-digit ZIP. UK blocks put the city on its own line with a generated postcode like BS12 4QT below it. Generic drops region-specific codes so nothing anchors the mockup to one country. No format includes a country line or UK county — add those manually if your form has the field.
can I use the output as database seed data
Yes — blocks are consistently structured (name, street, city or region, code), so you can split on newlines and map lines to columns in a seeder or factory. Generate the maximum of 20 per run and repeat runs for larger sets; each run is freshly randomized.
why do the same names keep showing up across addresses
The name pools are small — ten first names and ten last names, 100 possible combinations — and picks are independent. In larger batches the same first or last name recurs, and occasionally a full name repeats. For mockups this reads fine; for bigger seed sets, mix in your own name list.
