Below is a chart of common database fields such as email address, city, zip code and country name and the maximum possible length value that can be used. Field Name Character Length Example email address 254 see RFC5321 city 189 Longest City Name is Bangkok in Thai: Krung Thep Mahanakhon Amon Rattanakosin Mahinthara Ayuthaya Mahadilok Phop Noppharat Ratchathani Burirom Udomratchaniwet Mahasathan Amon Piman Awatan Sathit Sakkathattiya Witsanukam Prasit zip code 18 Country with the longest zip code format is Chile with NNNNNNN, NNN-NNNN country 90 Longest country name is Libya’s Arabic name prior to 2013: al-Jam-h-riyyah al-‘Arabiyyah al-L?
