Saddle up your merlion because we’ll show you a Singapore address example and walk you through the Singapore mailing address format step by step.

Hopefully, you will also learn about how Singaporean address validation and verification work. This knowledge can help you whether you’re sending mail to Singapore or processing Singaporean address data programmatically via an API.

Now, let's get into it with the basics. Singapore’s address format should be written as follows:

1. Addressee line - The recipient's name. Titles such as Mr. or Mrs. should be omitted or tailored to the recipient’s cultural background (English, Chinese or Mandarin dialects, Malay, Tamil/Indian, etc.).
2. House number and street name - The house number and street name are listed in this order, without commas between them.
3. Building - On a line by itself, include the building, if applicable.
4. Administrative area and postal code - The administrative area, followed immediately by the postal code goes on this line without any separating punctuation.
5. COUNTRY - SGP, in all caps, goes on the final line.

Formatting isn’t the only factor to consider when validating Singapore addresses. Organizations need to take Singapore’s address intelligence a step further: validate, verify, and standardize addresses to ensure accuracy for downstream processes that rely on it, such as onboarding, billing, shipping, and more. 

Address validation in Singapore checks address standardization against local postal standards and confirms that the address exists and matches an authoritative database. 

Manual Singapore address validation might be fine for some use cases, but if you’re looking to validate lists of Singapore addresses, using a Singapore address verification API can streamline this process, as well as retrieve missing or incomplete address information that might be helpful for your organization’s use case, such as RDI or DPV.
