The amendment that reshaped Malaysia's voter landscape fills only three pages. The Constitution (Amendment) Act 2019 — Act A1603 — did not write out a lengthy new procedure. It changed a handful of words in three places, and two of those changes moved millions of citizens onto the electoral roll.

The word "twenty-one years" became "eighteen years". The words "applies for registration" became "is registered". That is the core of Undi18 and automatic voter registration — stated in the sparest possible legislative language.

This page reports what changed, when it came into force, and how the mechanism works, according to the text of the Act and the official explanations of the Election Commission (Suruhanjaya Pilihan Raya, SPR).

## What changed in the constitutional text

Act A1603 contains only three substantive sections. Each one replaces specific words in the Federal Constitution.

**Section 2 — Article 47.** Article 47 sets out the qualifications for a person to be a member of Parliament. In paragraph (b), the words "twenty-one years" are replaced with "eighteen years". This lowers the minimum age to stand as a candidate for the Dewan Rakyat.

**Section 3 — Article 119.** Article 119 sets out who is qualified to vote. This section makes two changes:

- In Clause (1), paragraph (a): "twenty-one years" → "eighteen years". This lowers the voting eligibility age.
- In Clause (4), paragraph (b): "applies for registration" → "is registered". This one-phrase change is the legal basis for automatic registration — eligibility now depends on a person *being registered*, not on a person *applying* to be registered.

**Section 4 — Eighth Schedule.** The Eighth Schedule contains provisions for state constitutions. In section 5, "twenty-one years" is replaced with "eighteen years", lowering the age for State Legislative Assembly candidates in parallel.

Note the sequence: one constitutional amendment carries four distinct effects — the voting age, the method of registration, the age for parliamentary candidates, and the age for state assembly candidates.

## One amendment, two different events

Undi18 and Automatic Voter Registration (AVR / Pendaftaran Pemilih Secara Automatik, PPSA) are often mentioned together, but they are two different things that happened to come into force on the same day.

- **Undi18** is the lowering of the eligibility age — who can vote.
- **AVR** is the change in the method of registration — how a person gets onto the electoral roll.

According to the Election Commission, both were enforced together on **15 December 2021**. Section 3 of Act A1603 did not come into force immediately in 2019; the Act provided that Section 3 would begin operating on a date to be appointed by the Yang di-Pertuan Agong by notification in the Gazette. That appointed date was 15 December 2021.

## How AVR works

Under the old system, a person filled in Form A and applied to be registered. Under AVR, the Election Commission registers eligible citizens using data received from the National Registration Department (Jabatan Pendaftaran Negara, JPN).

According to the Election Commission, four conditions must be met to be registered automatically:

1. Malaysian citizen;
2. Aged 18 years and above;
3. Resident at the address as stated on the identity card; and
4. Not disqualified as a voter under the law.

Information on citizens who reach the age of 18 is received from JPN and processed daily. Before a person is entered onto the roll, the Election Commission states that it carries out cross-checks — online or manual — with JPN, the Malaysian Prisons Department, the Ministry of Health Malaysia, and the Ministry of Foreign Affairs, to ensure that only those who are eligible are registered.

Parliamentary and state electoral constituencies are determined based on the complete address at JPN. This is why the address matters: the Election Commission states that citizens with an incomplete or general address at JPN are **not** registered automatically, because the correct electoral constituency cannot be determined.

Malaysia's identity data is managed by the [National Registration Department (JPN)](/en/government/jpn) — the same agency that issues MyKad and verifies citizenship status.

## The Supplementary Electoral Roll: now monthly

New voters do not appear on the roll instantly. They enter through the Supplementary Electoral Roll (Daftar Pemilih Tambahan, DPT), which is certified and gazetted by the Election Commission.

According to the Election Commission, the DPT is now certified by no later than the 15th of the following month, and gazetted on the next working day of that month. This is one of the most notable changes: the DPT is now handled **every month**, replacing the quarterly cycle under the old system.

The effect on timing: the Election Commission states that the process for registering new voters now takes up to a month and a half, compared with four to five months previously.

### Checking your status

After turning 18, the Election Commission states that voting information can be checked after the 16th of the following month, through:

- The Election Commission portal — https://www.spr.gov.my or https://mysprsemak.spr.gov.my
- The MySPR Semak mobile app
- The State Election Office portal — http://ppn.spr.gov.my
- The Election Commission hotline — 03-8892 7018

## Claims and objections

AVR does not remove the right to correct the roll; it changes its timing. According to the Election Commission, claims and objections can only be made within the set DPT Review period.

- **Claims (Form C)** can be made by a citizen aged 18 and above who finds that their name is not in the DPT, or by a registered voter who finds an error in their particulars. The Election Commission states that no fee is charged for claims.
- **Objections (Form D)** are permitted only against a voter who has applied to change their electoral constituency. The Election Commission states that no objections are permitted against a voter who was registered automatically. A fee of RM10 is charged for each name objected to.
- **Appeals** against a rejected objection are permitted, with a fee of RM5 for each appeal.

For the first DPT under the new system — DPT Month 12/2021 — the Election Commission set a review period of six months, from 14 January 2022 to 13 July 2022. For subsequent months, the Election Commission states the review period is one month only.

## Effect on voter numbers

According to the Election Commission, when Undi18 and AVR were enforced, some 5.7 million new voters were registered. Of that number, the Election Commission states 1.4 million were citizens aged 18 to 20 — a group that had previously been entirely ineligible to vote.

The Election Commission states that the roll under this new system was used in the 15th General Election, the first general election held after Undi18 and AVR came into force.

## Common misunderstandings

- **"I have to register when I turn 18."** Not necessarily. If your records at JPN are complete, the Election Commission registers you automatically. You only need to act if your address is incomplete or you want to change your electoral constituency.
- **"Being registered means I can vote right away."** Not yet. According to the Election Commission, a person is only eligible to vote after the Election Commission has certified and gazetted the Supplementary Electoral Roll containing their name.
- **"AVR automatically updates my address."** No. The address comes from JPN's records. If your address changes, the Election Commission states you need to update it with JPN first, then apply to change your electoral constituency with the Election Commission.
- **"Undi18 is only about the voting age."** The same amendment also lowered the age for parliamentary candidates (Article 47) and state assembly candidates (Eighth Schedule) to 18.

## How this relates to other constitutional amendments

Undi18 is one example of a broader process. To understand why amendments like this one require a two-thirds majority in both Houses, see [how the Federal Constitution is amended](/en/law/constitutional-amendment) and [the text of the Federal Constitution itself](/en/law/federal-constitution). For how a Bill passes through Parliament, see [how a Bill becomes law](/en/law/how-a-bill-becomes-law) and the role of the [Dewan Rakyat](/en/government/dewan-rakyat).

## What's next

If you are close to or have just turned 18, check your status through the MySPR Semak portal after the 16th of the following month, and make sure your address at JPN is complete and up to date — because that address is what determines your electoral constituency. If your name is not in the DPT even though you are eligible, a claim using Form C can be made free of charge within the DPT Review period.
