ADDRESS_STREETS_NOT_FOUND

What it means

The street listing is read from the national address registers Spaw syncs — every street each one lists inside each postcode, in the register's own spelling. A country with no such register, or one whose register was synced before its listing existed, has no streets to answer with and answers this code.

A covered country answers it in three cases, and the message says which. "No street is listed at 9999 in CH." means the registers' coverage is complete and none of them holds an address at the postcode. Where a register whose coverage is complete holds addresses there but none on a named street, as in many Czech villages, the message says so. And a postcode the listing does not cover says that instead of reading as one with no street: a code outside the register's area (Northern Irish BT, forces BFPO and BF, and non-geographic BX codes are outside Ordnance Survey's Great Britain data), a postcode in a part of the country no installed register covers (Germany outside Berlin), or a postcode the installed register cannot vouch for (a British district Open Names files no street under).

Validating a single address is unaffected; it works from the same registers and answers a verdict rather than this code.
