A letter to The Straits Times Forum page on Monday from Mr Andrew Choo Ming Sing, appealing that the code "SIN" be dropped as an abbreviation of Singapore, struck a chord with readers.

The letter has been shared more than 13,900 times on Facebook. Some support Mr Choo's sentiment, while others think the writer is making a mountain out of a molehill.

Here are some codes that could raise a smile.

LAX - The International Air Traffic Association (IATA) code for Los Angeles International Airport has become as well-used as its full name. With more than 63 million passengers passing through in 2012, you'd hope the security is anything but.

ANT - A weightlifter would love to have the equivalent stength of an ant, which can lift objects 50 times its body weight. Sadly, the International Olympic Committee (IOC) code for Antigua and Barbuda doesn't convey Herculean powers.

BRA - Wearing a BRA on their chests didn't stop Brazil's athletes from grabbing 17 medals at the 2012 Summer Olympic Games. The support must have helped.

ACE - Lanzarote Airport, in Spain's Canary Islands, has been saddled with this optimistic IATA code.

JAM - Olympic victories for Jamaica's sprint stars, like Usain Bolt, are especially sweet when you're running for JAM.

PAN - A poor performance at the Olympics for Panama and the tabloid headlines practically write themselves: PANned.

SEX - The Sembach Kaserne United States Army installation in Germany has a rather unfortunate IATA code.

VAN - Vanuatu's IOC code is perhaps the most fitting on this list, as with only five athletes at the last Summer Olympic Games, their entire contingent could conceivably fit in a van.

SUI - Switzerland's athletes could be confused when Singaporeans start shouting their country's IOC code at a beautiful play on court.

ARS - It's a good thing that the abbreviation the English Premier League uses for Arsenal football club in its match hashtags end at three letters. If not, things could get a tad cheeky.
