Thai script is not recognized as a script in any of Singapore's official languages, even though English is less widely used in Thailand than standard Thai. Public hospitals Out of the eight general hospitals overseen by Singapore's Ministry of Health, only Singapore General Hospital has signages in the four official languages. Along Hospital Drive (where Singapore General Hospital is located) and various national medical centres, road directories are entirely in English. Within the hospital itself, signs for individual blocks, wards, Accident and Emergency department, Specialist Outpatient Clinics, National Heart Centre and National Cancer Centre have signs written in the four official languages.

Similarly in 2014, the Pioneer Generation Package (for senior citizens above 65 years of age in 2014 who obtained Singapore citizenship on or before 31 December 1986) made use of Chinese varieties commonly spoken in Singapore such as Hokkien, Cantonese and Teochew, and also Singlish in order to make the policies more relatable, and at the same time raise awareness about the benefits that this new scheme provides for them. These allowances of different language varieties is an exception to the four official languages. This exception is seen for campaigns that are deemed as highly important, and include the elderly, or those who are not as proficient in the English language as the target
