How many digits does a phone number in Luxembourg have?

Mobile numbers have 9 national digits. Fixed line numbers have 4 to 11 national digits. That is the national number, without the country code +352.

What is the country code for Luxembourg?

+352. From abroad, dial your own exit code, then 352, then the national number. From inside Luxembourg, the exit code for international calls is 00.

Which prefixes are mobile numbers in Luxembourg?

Mobile numbers start with 62, 65, 66, 67, 68 or 69 in national form; the mobile regular expression on this page gives the exact ranges (example: 628 123 456). The carrier table shows which prefix blocks were allocated to which operator.

Can a mobile number in Luxembourg be ported to another carrier?

Yes. Luxembourg has mobile number portability, so a prefix tells you the carrier a number was originally allocated to, not necessarily the one serving it today. Only a live carrier lookup (an HLR or MNP query) answers that.

The numbering plan of Luxembourg: formats, lengths, the regular expression for each line type and the prefix blocks allocated to each carrier, as ITU publishes it. A pattern says what a number looks like and where it was allocated; whether it is in service, and who serves it today, is a different question (below).

Test a pattern

Tick the line types you accept, copy the combined pattern, and paste numbers to see which range each one falls in. Numbers are reduced to their national digits first (no spaces, no +352, no trunk prefix); nothing leaves your browser.

Walk the prefixes

Type the first digits of a number in national form, or tap them: the operators holding blocks under those digits, then the block a full prefix falls in. 8 blocks held by 5 operators are on record.

Carrier prefix blocks

The operator each prefix block was allocated to, in national form, from the published allocation records for +352. Numbers are portable, so this is the original allocation, not necessarily the carrier serving a number today.
