Validate Indonesia Phone Numbers (+62)
Check whether a Indonesia phone number has the correct format before calling, texting, or saving it. Indonesian mobile numbers range from 10 to 13 digits. The domestic trunk prefix 0 is replaced with the country code +62 for international dialing. Carrier can be identified by the 3-4 digit prefix after 08. NumSwift validates each number against Indonesia's numbering rules, catching common errors like wrong digit counts, missing country codes, and invalid prefixes.

Frequently Asked Questions
▶How many digits should a Indonesia phone number have?
Indonesian mobile numbers range from 10 to 13 digits. The domestic trunk prefix 0 is replaced with the country code +62 for international dialing. Carrier can be identified by the 3-4 digit prefix after 08. NumSwift checks the digit count of each number against these rules and flags any that are too short or too long as invalid.
▶How can I tell if a Indonesia number is mobile or landline?
In Indonesia, mobile numbers start with 08 locally, with varying length between 10 and 13 digits. Landline numbers use different prefixes. NumSwift's validation engine recognises both types and formats each one correctly, so you can tell the type from the prefix of the extracted number.
▶Does validation confirm the number is active?
NumSwift validates the format and structure of the number against Indonesia's numbering plan — it checks digit count, prefix validity, and country code correctness. It does not perform a live carrier lookup, so it cannot confirm whether the number is currently active or in service.
▶Can I validate Indonesia numbers in bulk?
Yes. Paste a large block of text containing multiple Indonesia phone numbers and NumSwift extracts and validates them all at once. Only numbers matching Indonesia's +62 format appear in the results — everything else is filtered out. There is no limit on how many numbers you can validate in a single paste.
