CAP (postcodes) of Italy
Posted by Cascafico on 29 August 2018 in English. Last updated on 30 September 2020.Abstract
Codici di Avviamento Postale (postcodes) are propriety of Poste Italiane S.p.A. Sometimes OSM mappers who love the completeness of data cannot get this codes from open sources.
The below procedure is a simple workaround, taking advantage of iPA (Public Administration index) OpenData which lists widespread public offices in Italy.
Getting data
Go to iPA site and download “Amministrazioni” file. Here you can read when it was last updated.
Filtering data
On downloaded file, run:
$> awk –field-separator=”\t” ‘{ print $3”,”$6 }’ amministrazioni.txt | sort -u > CAP.csv
The command above takes TAB-separated columns 3 and 6 (municipality and postcode), sorting uniques and writes a comma-separated file.
Alternatively, you can switch columns for postcode sorting:
$> awk –field-separator=”\t” ‘{ print $6”,”$3 }’ amministrazioni.txt | sort -u > CAP.csv
Multi postcode municipalities:
Some cities have more than one postcode: it could be someway useful listing public office addresses (column 10) to approximately identify the area:
$> awk –field-separator=”\t” ‘{ print $3”,”$6”,”$10 }’ amministrazioni.txt | sort -u > CAP.csv
Take a look
To count extracted postcodes, simply:
$> wc -l CAP.csv
8638 cap.csv
For an overview of firsts and lasts codes:
$> head -3 CAP.csv && echo “…” && tail -3 CAP.csv
