All of the example accepted numbers work, a part form that format. Thanks Can you confirm if the telephone number in the format: 020 8123 4567 is valid using the regex?

So far, 023, 024, 028 and 029 are also in use. Those are 02x codes. There are no 02xx area codes. The UK number format can be 2+8, 3+7, 4+6, 4+5, 5+5 or 5+4, where the leading 0 'trunk code' is not included in the digit count. Ofcom maintain a detailed list of the allocations, published weekly as an Excel spreadsheet. The London 020 area code is not the only (02x) area code.

As such, if we can expect that a user may enter: 0208 123 4567 +44 (0) 208 123 4567 ...we should allow those. They are valid, in my opinion, in that people may enter them, and it is trivial to convert these into a standard format for insertion into a database. This was originally written - as you correctly surmised - for mainland UK, and so the Channel islands were not supported. I should amend this though, you are correct, and I shall. Thanks for your comment! Hi,

I am sure that people in the Channel islands (07624) will not be very impressed with that.

Mobile telephones in mainland UK recently started using 075xx too.

** 0208 123 4567 **

There is NO 0208 area code. London is 020. Just 020.

** +44 (0) 208 123 4567 **

The form with (0) in it is NOT valid.
