HI Vinay ,

 have requirment where it has to read an email subject if it contains a policy number it has to create case but problem is that it sometimes its considering the mobile number also. to avoid this i am written below class please help me whether its correct or not. 
Regular expression:

public static final String REGEX_PATTERN_EXACT_NUMBER = '^[A-Za-z]{0,4}[0-9]{6,10}';
Pattern regexPattern = Pattern.compile(REGEX_PATTERN_POLICY_NUMBER);

I am calling below method like this .

policyNumbersMap = Case.populatePolicyNumberMap(
                            policyNumbersMap,
                            regexPattern.matcher(policyCase.Subject),
                            policyCase
                    );


public static Map<Id, Set<String>> populatePolicyNumberMap(Map<Id, Set<String>> policyNumbersMap, Matcher match, Case aCase)
    {
        Pattern regexExactPattern = Pattern.compile(REGEX_PATTERN_EXACT_NUMBER);
		String[] emailAddressList = new String[]{'tel', 'telephone', 'phone', 'fax', 'F','+27','T'};
		  
        if (policyNumbersMap == null)
        {
            policyNumbersMap = new Map<Id, Set<String>>();
        }
		for (String emailAddress : emailAddressList) 
		{
          System.debug('Email address: ' + emailAddress);
          Matcher m = regexExactPattern.matcher(emailAddress);
          if (m.matches()) 
		  {
		    null;
		  }
			else
			{
			Set<String> values = policyNumbersMap.get(aCase.Id);
                    if (values == null)
                    {
                        values = new Set<String>();
                    }
                    values.add(exactMatch.group());
                    policyNumbersMap.put(aCase.Id, values);
			}
		    
          }
		  return policyNumbersMap;
       
         }
