How does postcode → city work in bexio contacts?

You type the fourth digit of the postcode, quintio fills in the city — right in the bexio contact form, from Switzerland’s official directory of localities. The fill is always marked: below the city field appears the line “City filled by quintio”, and the postcode field carries a small dark-blue corner triangle as a provenance mark. What you type yourself stays — quintio never overwrites your own input.

Where do the city names come from?

From Switzerland’s official directory of localities (swisstopo), which also covers Liechtenstein. The directory is delivered through your quintio account and kept up to date — that is why postcode → city only works after signing in to the extension.

What happens with ambiguous postcodes?

If several localities share one postcode, quintio fills in the canonical city and offers the others in a small chip below the line — one click takes over the alternative. Example: 4535 fills “Hubersdorf”, the chip offers “Kammersrohr”.

Why does nothing happen sometimes?

In four cases this is deliberate:

• The country is not Switzerland. For foreign addresses quintio holds back — the directory is a Swiss one.
• The postcode is a special or PO box postcode (for example 3000 Bern): such numbers are not in the official directory of localities, so quintio fills in nothing instead of guessing.
• You are not signed in. Then, as you type, the note “PLZ → city is tied to your quintio account” appears with a “Sign in” button.
• The directory is currently not reachable — then it says “PLZ directory currently unavailable”, and you type the city by hand as before.

Does quintio overwrite my input?

No, never. quintio only fills the empty city field; if you type the city yourself or over the fill, the marker disappears and your spelling stands. Nothing is saved in bexio anyway until you save the form yourself — the extension never writes anything back on its own.

All three features at a glance are on the extension page — and the installation is covered in installing “quintio for bexio” and signing in.
