Phone Number Normalization Rule Regular Expressions
The pattern-matching notation of regular expressions makes it possible to quickly parse large amounts of text to find specific character patterns; to extract, edit, replace, or delete text substrings; or, to add the extracted strings to a collection in order to generate a report. You use .NET regular expressions to specify the phone pattern and the translation pattern as follows:
-
Phone pattern regular expression. This consists of designators and variables that represent specific sets of numbers. For example, the phone pattern regular expression of ^9(\d{7})$ describes phone numbers that consist of the number 9 followed by any seven digits.
-
Translation pattern regular expression. This consists of the + symbol, numbers, and the $ symbol. The $ symbol captures the items of the phone pattern regular expression that are included inside the parenthesis. The number following the $ symbol must be less than or equal to the total number of captures specified by the phone pattern regular expression.
For example, the translation pattern regular expression of +1425$1 describes a translation that adds a prefix of +1425 to the captures (the phone pattern items in parenthesis). If the phone pattern regular express is ^9(\d{3})(\d{4})$ (containing two captures), the number following the $ sign can only be 1 or 2.
The following table shows sample normalization rules and the corresponding values for the rule name, description, phone pattern, and translation pattern.
