| 59 | + * |
| 60 | + * 1. International format: `^\+[1-9]\d{10,13}$` |
| 61 | + * - Must start with '+' followed by a digit 1-9 (no leading zeros after country code) |
| 62 | + * - Followed by 10-13 additional digits |
| 63 | + * - Total length: 12-15 characters (including the '+') |
| 64 | + * - Examples: +31612345678, +1234567890123 |
| 65 | + * |
| 66 | + * 2. National format: `^[1-9]\d{9,13}$` |
| 67 | + * - Must start with a digit 1-9 (no leading zeros) |
| 68 | + * - Followed by 9-13 additional digits |
| 69 | + * - Total length: 10-14 digits |
| 70 | + * - Examples: 1234567890, 12345678901234 |
| 71 | + * |
| 72 | + * 3. Dutch mobile format: `^06\d{9,13}$` |

| 74 | + * - Followed by 9-13 additional digits |
| 75 | + * - Total length: 11-15 digits |
| 76 | + * - Examples: 06123456789, 061234567890123 |
