Got a call from an unknown number? Need the area code of an Indonesian city, or a country code before calling abroad? Kode Area Telepon & Cek Nomor answers it right on your phone, with no internet needed.

CHECK A NUMBER
Type or paste any number and tap Check. The app recognises the type of number automatically:

- International numbers (+60, +65, +966 and more): the country
- 0800 toll-free numbers and emergency numbers (110, 112, 113 and more)
Any format works: 0812..., +62 812..., 62812..., (021) 1234-5678, 0021..., 001-65-...

HIGHLIGHTS
1. 100% offline: every lookup works without internet. Internet is only used for ads that support development.
2. Private: numbers you type are not stored, not kept in a history and not sent to any server. The app does not read your contacts or call log.
3. Light and fast: data is loaded once on your phone so results appear instantly. Soft pastel design that follows light or dark mode.
4. Call & Copy buttons: open your dialer with the number filled in, or copy numbers and codes with one tap.

PLEASE NOTE
- The operator is identified from the number prefix, i.e. the operator that issued the number.
- Data comes from public sources and may be incomplete or inaccurate; regions marked "Perkiraan" have no reliable source yet.
- Do not use this app for fraud, spam or anything that harms others.
- The app shows Google AdMob ads (may use the device advertising ID).

Note: This app does not track location, does not show the name or photo of a number's owner, and does not check a number's status with any operator server.

IMPORTANT DISCLAIMER:
This app is NOT an official government app. It does NOT represent, is not affiliated with, and is not endorsed by any government entity (including Komdigi, the Ministry of Home Affairs/Kemendagri, and BPS), Telkom, or any mobile operator. It is not connected to any government or operator database and cannot find the name, address or location of a phone number's owner. It only explains what the digits mean: the region of a landline area code, the operator that issued a mobile prefix, or the country of an international code.
