Singapore (SG)¶
National-ID patterns loaded when you pass countries=["SG"] (or "all"). Universal patterns always stay.
This is a detector, not a legal opinion
id-extract matches the shape of these numbers. A hit is not proof that the value was issued, is still valid, or that the cited statute applies to your document. Checksums, where present, only test the extra digit.
NRIC_SG — NRIC / FIN¶
The National Registration Identity Card number for citizens and permanent residents (prefix S or T) or the Foreign Identification Number (prefix F, G, or M). M is the FIN prefix issued from 2022.
| Package type | NRIC_SG |
| Shape this package looks for | S, T, F, G, or M + 7 digits + letter |
| Checksum | none in this package. ICA does not publish the check-letter algorithm. |
| Example (synthetic) | S1234567D |

UEN_SG — Unique Entity Number (UEN)¶
The standard number for an entity registered in Singapore. Businesses registered before the current company form use eight digits and a letter. Local companies use nine digits and a letter, and the first four digits are the year of registration. Other entities use a T, S, or R, a two-digit year, a two-letter entity type, four digits, and a check letter. A failed check is dropped.
| Package type | UEN_SG |
| Shape this package looks for | 8 digits + letter, 9 digits + letter, or TSR + entity type + 4 digits + letter |
| Checksum | UEN check letter for each of the three forms. A local-company number whose year is in the future is rejected. A failure is dropped. |
| Example (synthetic) | 201912345R |
