Nummeropslag: Who Called?

Look up any Danish number in seconds: see the company from CVR, a spam score and reviews before you answer. Private and free — we never touch your contacts.

Who's calling from that unknown number? With Nummeropslag you can look up any Danish phone number in seconds and instantly see whether to pick up — company, spam rating or private person.

HOW IT WORKS Enter an 8-digit Danish number and get the whole picture in one place: who's behind it, a spam score, a trust meter and reviews from other people.

WHAT YOU GET • The company behind the number — straight from the official, public CVR business register. Real data, not scraped phonebooks. • Person or business? — instantly see whether an unknown number belongs to a registered company or a private individual. • Spam & scam check — a clear spam score and trust meter before you answer. • Community reviews — read what others experienced and leave your own: spam, scam, telemarketing, company or private. • One-tap reporting — flag spam and fraud numbers and help everyone else. • Spam labels in the Phone app — known spam numbers are labelled and the worst are blocked automatically, even offline. Turn it on under Phone → Call Blocking & Identification. • Google-verified business info — address, industry and ratings where available. • SMS filter — messages from unknown senders that match known spam numbers are moved to Junk automatically. Enable it under Settings → Apps → Messages → Unknown Senders.

BUILT INTO IPHONE • Siri & Shortcuts — say "Look up number" to jump straight to search. • Spotlight — start a lookup from your Home Screen. • Share a number — share from Phone, Messages or Contacts to look it up. • Universal links — nummeropslag.dk links open directly in the app. • Widget & Control Center — start a lookup from the Home Screen or Control Center.

PRIVACY ABOVE EVERYTHING Most caller-ID apps upload your entire contact list. Nummeropslag never does. • We never copy your phonebook. • We don't collect personal data and we sell nothing. • Only anonymous, aggregated signals. GDPR-friendly by design.

DATA SOURCES • CVR — the official Danish business register. • The Danish Number Register (SDFI, CC0 open data) for carrier and number type. • Anonymous reports from real users.

Free to use. Available in Danish, English and Ukrainian.
