Is the código postal a valid Spanish postal code?

It is five digits, the correct Spanish código postal length, and its first two digits match the province code of the chosen localidad — 28 for Madrid, 08 for Barcelona, 46 for Valencia, and so on. It is format-valid but not a guaranteed live delivery code.

How is a Spanish address structured?

It runs as vía type and name, then número, then an optional piso (for example Calle Mayor, 12, 3º B), with the código postal and localidad on the next line. The generator follows this convention.

Do the localidad and código postal agree?

Yes. Each localidad carries its province code as the first two CP digits, so Madrid yields 28xxx, Barcelona yields 08xxx, and Sevilla yields 41xxx. The remaining three digits are random.

Can these be used to actually ship something?

No. They are fabricated for testing only. The combination of street and código postal is randomized and not a real deliverable address. Use them solely in development and QA.

Does anything leave my browser?

No. The whole address is built locally with no network calls, so your generated test data stays on your device.

Fake Address Generator (Spain)

A fake Spanish address generator produces correctly formatted addresses for Spain, following the local convention of vía type and name, número, and optional piso, with a five-digit código postal whose first two digits identify the province. It is meant for developers and testers exercising Spanish-language forms and EU checkout flows.

How it works

The generator keeps the province and localidad consistent:

A localidad is chosen, each carrying its two-digit province code.
A vía type (Calle, Avenida, Plaza, and so on) and name are picked, followed by a número and, most of the time, a piso such as 3º B or 2º Izq..
A código postal is built as five digits: the first two come from the localidad’s province code (28 Madrid, 08 Barcelona, 46 Valencia, 41 Sevilla), and the remaining three are random.
The localidad and province name complete the address block.

Tips and notes

The first two CP digits are province-correct, satisfying the most common regional and length checks; the full code is not tied to a specific street.
A piso is included on most addresses, mirroring how Spanish residential addresses commonly include floor and door.
