Description |
Intended to validate html5 form input of type=tel in internation E.164 format, to validate Belgian phone numbers for valid routes and length. As Belgium has a closed number plan the regex is relatively short and in theory any subscribing number is possible, even ones starting with 0, 1 or 9 as the area code needs to be dialed always. This regex can be used in PBXes as part of a larger dial plan string to allow immediate dialing as soon as the correct number of digits has been entered. Replace \+ with your international dialing prefix. |
