Isogrammic Place Names

Anu Garg’s A.Word.A.Day newsletter theme of the week (January 24, 2011) was isograms — words which do not repeat any of their letters.

In the weekly follow-up newsletter, Al Reynolds pointed out several places in the UK with isogrammic names, Plymouth with 8, Ilfracombe with 10, and Buckfastleigh with 13. He wondered if there were place names with more than 13 letters where none appear more than once.

I wondered, too, so I ran a little program on the geonames.org database of over 8 million place names. The answers depend on the rules for the search, so I grouped the results into the tables below. Click on the name to google for more information or click the globe icon to find the place on the map. The two letter country codes are decoded at iso.org.

In August, 2019, Anu ran a week of palindromes, leading me to create a page listing the longest Palindromic Place Names. I took the opportunity to update the Isogram list from the now almost 12 million place names in the database.
