Title Test Details Match UK telephone number in any format.
Expression
^\(?(?:(?:0(?:0|11)\)?[\s-]?\(?|\+)44\)?[\s-]?\(?(?:0\)?[\s-]?\(?)?|0)(?:\d{2}\)?[\s-]?\d{4}[\s-]?\d{4}|\d{3}\)?[\s-]?\d{3}[\s-]?\d{3,4}|\d{4}\)?[\s-]?(?:\d{5}|\d{3}[\s-]?\d{3})|\d{5}\)?[\s-]?\d{4,5}|8(?:00[\s-]?11[\s-]?11|45[\s-]?46[\s-]?4\d))(?:(?:[\s-]?(?:x|ext\.?\s?|\#)\d+)?)$
Description
Step 1: Test that the input is a UK phone number. Later patterns extract the prefix, NSN and extension, and further tests check the NSN for length and validity. The above pattern matches optional opening parentheses, followed by 00 or 011 and optional closing parentheses, followed by an optional space or hyphen, followed by optional opening parentheses. Alternatively, the opening parentheses are followed by a literal + without a following space or hyphen. Any of the previous options are then followed by 44 with optional closing parentheses, followed by optional space or hyphen, followed by optional 0 in optional parentheses, followed by optional space or hyphen, followed by optional opening parentheses (international format). Alternatively, the pattern matches optional opening parentheses followed by the 0 trunk code (national format). This is followed by the area code and phone number in 2+8, 3+7, 3+6, 4+6, 4+5, 5+5 or 5+4 format with or without spaces and/or hyphens. This also includes provision for optional closing parentheses and/or optional space or hyphen after where the user thinks the area code ends and the local number begins. The pattern allows any format to be used with any UK number. The display format must be corrected by later logic if the wrong format for this number has been used by the user on input. The pattern finally ends with optional space or hyphen followed by x, ext and optional period, or #, followed by a three or four digit extension number. Once the input has been confirmed as being a telephone number using the above pattern, another RegEx pattern should extract prefix, NSN and extension and then the NSN should be further tested for length and validity. (Order fixed for even greater efficiency: shorter area codes match first.)

Title Test Details Extract NSN, prefix and extension from UK telephone number.
Expression
^\(?(?:(?:0(?:0|11)\)?[\s-]?\(?|\+)(44)\)?[\s-]?\(?(?:0\)?[\s-]?\(?)?|0)([1-9]\d{1,4}\)?[\s\d-]+)(?:((?:x|ext\.?\s?|\#)\d+)?)$
Description
Step 2: After step 1 has verified the input is likely to be a UK telephone number, this pattern extracts the NSN part of the number so that it can be passed to another routine that will check it for length and validity. $1 is 44 (international format) or null (use 0 for trunk code - national format). $2 is the NSN. $3 is the extension number.
Matches
020 3000 5555, (020) 3000 5555, +44 20 3000 5555, 00 44 20 3000 5555, 011 44 20 3000 5555, 0203 000 5555, 02030 005 555, (+44) 20 3000 5555, (+44 20) 3000 5555, and many others, any with NSN of 10 or 9.

Title Test Details Validate UK telephone number NSN by initial digits and length (simple version).
Expression
^((1[1-9]|2[03489]|3[0347]|5[56]|7[04-9]|8[047]|9[018])\d{8}|(1[2-9]\d|[58]00)\d{6}|8(001111|45464\d))$
Description
Step 3: Validate the NSN produced from the pattern in step 2 and check it for length and validity. The pattern here is fairly basic. More detailed patterns for each number type are available elsewhere. Step 4 is to format the number correctly. This needs a variety of RegEx patterns each based on the initial digits and number length.

Description
Step 3: Validate the NSN produced from the pattern in step 2 and check it for length and validity. The pattern here is very detailed matching every valid UK prefix, and rejecting large numbers of non-valid ranges. Step 4 will be to format the number correctly. This needs a variety of RegEx patterns each based on the initial digits and number length as shown in the article mentioned below.
