Why it works

The link is the address

No database and no lookup table. The id decodes straight to the district, so there is nothing to expire.

Any zone code fits

Codes like [Q]C2-1-CDO or R-10/5 survive intact. The encoding is URL-safe everywhere, with no escaping.

Mint links anywhere

A county GEOID plus one line of code. Put a link beside every parcel in a spreadsheet, map or API.

Make a link

// JavaScript (Node)
const id = `${geoid}.${Buffer.from(zoneCode).toString('base64url')}`;
const url = `https://zoningcode.link/${id}`;

// "51107" + "R-1"  →  https://zoningcode.link/51107.Ui0x
