Phone Number Validation and Verification Services: Various APIs and services can validate the format and often the type (mobile, landline) of an Indonesian phone number. These are primarily tools for data hygiene and accuracy, ensuring the numbers you already possess are correct and active, rather than for generating new contacts.
Reverse Phone Lookup Services (Highly Restricted): Services like Truecaller exist, which rely on user-contributed data. However, the legality and comprehensiveness of such services for identifying personal information tied to Indonesian phone numbers for commercial or public use are severely limited by the PDPL and Kominfo/BRTI regulations on privacy and unsolicited calls.
Indonesia's PDPL and Kominfo/BRTI regulations impose significant obligations on organizations processing phone numbers:
Consent: The PDPL prohibits processing personal luxembourg phone number library data, including phone numbers, without the explicit consent of the individual. This is particularly crucial for telemarketing and unsolicited communications. Consent must be clear, informed, and for a specific purpose, and individuals have the right to withdraw their consent at any time.
Purpose Limitation and Data Minimization: Personal data can only be collected for specific, legitimate purposes and should not be retained longer than necessary.
Transparency: Data subjects must be informed about why their data is being collected, how it will be used, and their rights under the PDPL.
Data Subject Rights: Individuals have extensive rights, including the right to access, correct, erase, restrict, or object to the processing of their personal data. They also have the right to be informed of any data breach within 72 hours.
Telemarketing Regulations: Kominfo and BRTI regulations (e.g., Ministerial Regulation No. 5 of 2020) require electronic system providers (including telecommunication operators) to implement measures to prevent unsolicited communications. This often involves the use of 'spam filters' and mechanisms for users to report unwanted calls. There are also specific rules around call times and disclosure for telemarketing. Users are generally given options to opt-out.
