A Luxembourg number gives your business a local presence with country code +352. Luxembourg has no trunk prefix, so a number is dialled the same way nationally, and from abroad callers simply add +352 in front.
Number types in Luxembourg
- Local numbersGeographic numbers with a city or regional area code. Customers see a familiar local number and call you at local rates.
- National numbersNon-geographic numbers that work nationwide without tying you to one city — ideal for a single number across the whole country.
- Mobile numbersNumbers from mobile ranges, for services that need a mobile-looking number. SMS capability depends on the range.
- Toll-free numbersFree for your callers from most networks. You cover the inbound cost, which lowers the barrier for sales and support calls.
