Jakartaculture & etiquette

The dos and don’ts that help you fit in fast — and avoid the mistakes newcomers make in their first weeks.

What to know before you go

Get your SKTT within fourteen days of the ITAS — it unblocks everything else

Critical

Once your limited-stay permit is issued you must report to the Dukcapil (civil registry) office of the administrative city you live in — South Jakarta, Central, West, East or North — to be issued an SKTT residence certificate. Most offices also want a police report (STM) and a letter from your RT/RW neighbourhood head first. It is the SKTT, not the KITAS card, that banks, landlords and utility providers actually ask to see, and the immigration and civil-registry systems now cross-check, so the gap shows up later at extension time.

Ask how high the water came, in centimetres, before you sign anything

Critical

Jakarta floods every wet season and the difference between streets is enormous — some kelurahan take fifteen centimetres and drain by lunchtime, others take a metre and stay under for days. North Jakarta is sinking at rates measured in tens of centimetres a year in the worst spots, so the historical record is a better guide than the developer's brochure. Ask the neighbours and the RT head, not the agent, and ask about specific years rather than in general.

Jakarta is still legally the capital — do not plan around Nusantara yet

Important

The 2024 law that turns Jakarta into the Daerah Khusus Jakarta only takes effect once the President signs a decree moving the capital to Nusantara, and that decree has not been issued. The Constitutional Court said so explicitly on 13 May 2026 when it rejected a challenge to the State Capital Law. The transition has slipped repeatedly. Nothing about your permit, your tax office or your employer's registration changes until the decree exists, and advice premised on the move having happened is simply wrong.

Do not drink the tap water, and find out where yours comes from

Important

Piped water reaches roughly four fifths of the city and is not potable at the tap regardless; households and buildings routinely top up from groundwater, which is exactly what makes the city sink. Galon refill water is the norm for drinking and cooking. If you are renting a house rather than an apartment, ask whether it is on the PAM Jaya piped supply or a well, because the answer predicts both your water bill and how reliable supply is in the dry season.

Air quality is a dry-season problem, and it is worst in the mornings

Important

Jakarta's PM2.5 is worst from roughly June to September when there is no rain to wash the air, and readings peak in the morning inversion before the city heats up. Indonesia rates worst in Southeast Asia on IQAir's country tables. A HEPA purifier for the bedroom is a normal purchase here rather than a precious one, and it is worth checking whether a flat's windows actually seal before you take it.

Learn the ganjil-genap map before you buy a car

Good to know

On about 26 road segments, cars whose plate ends in an odd number may only run on odd dates and vice versa, weekdays from 06:00 to 10:00 and 16:00 to 21:00, with fines up to IDR 500,000. Motorbikes and battery-electric cars are exempt, national holidays are not restricted, and the list of segments changes. Most people solve it with a mix of MRT, TransJakarta and ojol rather than a second car.

Some of this may be out of date. Spotted something inaccurate? Help us keep it right for the next newcomer.
