Who keeps calling me?

When the same number rings over and over, the way the calls arrive tells you almost as much as the number itself. Read the pattern first, then identify the caller, then stop it.

Read the calling pattern

Repeated calls during working hours, with a voicemail, usually mean something real: a courier, a clinic confirming an appointment, a debt collector, or a salesperson. Calls at odd hours, from numbers that shift slightly each time, and never a voicemail, mean an automated dialler. That distinction decides everything you do next.

Identify the caller

Search the number in quotes, and check whether it is a mobile, a geographic landline or a VoIP line. A real organisation calling you repeatedly almost always has a findable, publicly listed number. A reverse lookup fills in the rest: likely owner, region, line type and whether the number has been reported before.

If a voicemail names an organisation, do not ring the number that called. Look the organisation up yourself and ring the number published on their own website.

Stop the calls

Block the number in your phone, and turn on the spam filtering your carrier offers. If the caller changes number every time, blocking will not keep up, and the filter matters more than the block list. Telemarketing you did not agree to can be reported, and scam texts are handled by the Department of Internal Affairs.

Never press a key to be removed from a list during an automated call. A response confirms the number reaches a real person, and that makes it more valuable, not less.

Common questions

Why does the same number ring and hang up?

Either an automated dialler with no agent free when you answered, or wangiri, where one ring is the entire point and the profit comes from you ringing an expensive number back.

Does blocking actually work?

For a single persistent caller, yes. Against a dialler that changes number every time, no, and your carrier's spam filtering is the thing that helps.

Can I find out who is behind a withheld number?

Not from the call itself, because the number is not delivered to you. If it becomes harassment, your carrier and the Police can act on the call records, which you cannot see.
