Key Luxembourg number prefixes (no geographic area codes)
Luxembourg does not use separate geographic “area codes” that you add/remove with a trunk prefix. Instead, the first digits of a number help indicate fixed-line vs mobile ranges.
| Range / Prefix | Typically used for | Example |
|---|---|---|
| 2x (often 24 / 26 / 27) | Fixed lines (many newer assignments start with 2) | +352 26 12 34 56 |
| 6×1 + 6 digits | Mobile numbers (network code + subscriber digits) | +352 621 123 456 |
| 112 | Emergency services | 112 |
Note: Number lengths and assignments can vary (legacy ranges exist). For authoritative numbering details, use official/regulator documentation.
