LTA car prefix data, August 1972 to today

What year is my car, from its plate?

A Singapore car's registration plate dates it almost exactly, because LTA opens a new prefix every few months and never reuses one. The prefix in front of the number is what matters: SPK is the one being issued right now, opened in June 2026, which makes any car wearing it 4 months old.

Look up a plate or prefix

Type a full plate ("SNQ1234A") or just the prefix ("SNQ") to see when those cars were registered. The table below answers the same thing.

Every prefix LTA has issued

260 prefixes, August 1972 to June 2026. Each one's window runs from the month it opened to the month before the next prefix started — LTA never publishes an explicit end date, so that next-prefix month is the only bound there is.

How a plate is built up

A Singapore car plate has three parts. The prefix — one or two letters, then a letter, like SPK — is what this whole page is about: it names the batch the car was registered in. The running number after it, up to four digits, is simply the next number LTA had free in that prefix; it carries no meaning beyond order. The final check letter is where people's guesses tend to go wrong.

LTA does not publish how the check letter is calculated. Several different weightings circulate online, presented confidently and contradicting each other — which is exactly the sign that none of them is confirmed on its own say-so. This page states only what is verifiable: the last letter is a check letter LTA computes from the prefix and the running number.

One of those weightings can now be tested, because LTA's bidding list prints the check letter beside every number still available — thousands of known-good plates at a time. One rule reproduces every single one of them, and the plate bidding page sets it out along with how many plates it has been checked against. It is still not official, and the prefixes on this page reach back to 1972 while the evidence only covers the series open today — so there is still no calculator here, applied blind to a fifty-year-old plate.

Plates also come in more than one finish. Non-reflective plates are white lettering on black. Reflective plates are black lettering on white at the front, and black lettering on yellow at the back:

SPK is a real prefix; 1234 and the final A are a made-up running number and check letter for illustration, not a lookup result. Character sizes and spacing above follow LTA's published spec: 70mm tall, 50mm wide characters, 10mm between two adjoining letters or two adjoining digits, 20mm between a letter and a digit. The real plate typeface is Charles Wright; no digitisation of it carries a licence that can be shipped from here, so the lettering is Arial Bold pinned into the same 50mm cell.

LTA also runs several plates that look different again — Off-Peak Car, Revised Off-Peak Car, Weekend Car, and the Classic and Vintage schemes. LTA's own page shows these only as images and never states their colours in writing, so none are reproduced here; see LTA's standard registration page for how they look.

Malaysian plates that look Singaporean

A black plate with white lettering and an S at the front is not automatically a Singapore car. Malaysia registers Sabah under an S prefix too — SK 8012 F — and Sabah cars are a common sight here. Sarawak, often named as the culprit, is actually the easy one: every Sarawak plate starts with Q, and Singapore has never issued a Q prefix to a car — not once in 260 prefixes since August 1972. A Q plate is never Singaporean, and a Singapore plate is never Sarawakian.

What makes Sabah genuinely confusable is the finish. Malaysia's private plates are white on black front and back — the same combination as a Singapore non-reflective plate. Side by side, only the letters differ:

The Malaysian examples are drawn to Singapore's character spec so the three sit on the same scale for comparison. Malaysia publishes its own dimensions, which are not these — the point here is the colours and the shape of the format, not the millimetres.

The test that always settles it is the one this whole page is built on: Singapore's prefix list is finite and published. There are exactly 260 of them and they are all in the table above. If the letters in front of the number are not in that table, the car is not registered in Singapore — which is why the lookup refuses an unknown prefix instead of guessing at one.

For a quicker read at a distance, the second letter is often enough. Singapore has only ever used 11 of them — B, C, D, F, G, J, K, L, M, N, P — so:

  • SC, SF, SJ, SN, SP — Singapore. Sabah has no division on these letters.
  • SA, SS, ST, SU, SW, SY — Sabah. Singapore has never opened a prefix on these.
  • SB, SD, SG, SK, SL, SM — could be either, and the table is the only way to be sure.

Two further tells, once you are close enough to read the whole plate. A Singapore rear plate may be black on yellow; Malaysian private plates are black front and back, so a yellow rear plate is not one. And the trailing letter means different things: on a Singapore plate it is a check letter computed from everything before it, while on a Malaysian plate it is simply the next letter in a sequence that advances when the numbers run out.

A few things the data gives away

Two letters have never appeared anywhere in a car prefix, across 260 prefixes and over half a century: I and O. LTA does not say why, but the standard explanation — repeated widely enough to be worth stating, though it is not an LTA claim — is that I and O are too easily misread as the digits 1 and 0.

The series itself only changed once. Cars were registered under an E prefix from August 1972; the last one, EZ, opened in February 1984. Six months later, in August 1984, LTA started on SBA and every prefix since has run under S. Nothing in the published data says why the letter changed or what the 6-month gap was for.

A smaller oddity: within a two-letter block, LTA has occasionally skipped a letter it would otherwise have used next — SBS, SCB, SCC, SCD, SCS, SCT, and 8 others. As with the never-used letters, no published reason exists for any of them.

How fast prefixes get used up

A prefix holds a fixed block of running numbers, so how quickly LTA moves on to the next one is a rough stand-in for how many cars were being registered — rough, because LTA has never published how many plates actually fit in a prefix, and it reserves and retires combinations for reasons that are not public. Read the line below as a shape, not a count: the slowest prefix on record, EF, took 22 months to need a successor; 99 prefixes opened a month or less after the one before them, almost all of them since the 2000s.

Sources

Prefix and opening-month data: LTA DataMall, Car Prefix (Identification Marks) For Cars Registered In Singapore, fetched 10 September 2026. LTA refreshes this dataset roughly once a year, so a prefix that opened very recently may not be reflected here until the next refresh. Plate colours, dimensions and spacing: LTA's standard registration page. Malaysian plate formats and colours, for the comparison above: Vehicle registration plates of Malaysia. That is the one claim here LTA cannot vouch for, and the Sabah division letters in particular are a secondary source rather than an official register. Not affiliated with or endorsed by LTA.
