Even if you remove all the descriptive groups so it's just the RE, JavaScript still can't compile or use this RE.

This doesn't seem to work.  I tested in Expresso and it returns nothing.  I even pasted in the matches listed here and it doesn't work.

(?n:) and (?i:) are regex options. They aren't supported by all implementation of regex or have the same syntax.  (?:n) is  an explicit capture option, meaning only named groups are captured. (?i:) is the ignorecase option.

I really appreciate the regular expression and I think its great!  I've been looking for something like this for a while now ... Didn't want to have to write it from scratch ;-)  I understand everything in the regular expression except the (?n: and (?i: in front of the two name captures (?<address1> and (?<address2>.  Could you elaborate on those? -TIA

Most likely the named groups (?<address1>...) are not supported or the syntax is different if it is.  If you do not need the address parts you can simply remove all the names fields (the question mark, the angle brackets and the text between them)

I am trying to use it with preg_match(), and it keeps giving me errors.
EX> Warning: Compilation failed: unrecognized character after (?< at offset 6 in /home/fallen/public_html/work/contactSpidey.php on line 637.
Any idea why its doing that?

Updated RE to capture address parts.
Also adding check for optional secondary unit
Changed the separator to allow spaces or new line

This RE accepts most US Addresses in format ### street city, State zip.
It doesn't account for secondary Address lines or units (ie Apt ##  or Suite ###)
Street and City names must be in proper case
State Abbreviation in all Caps
No  puncuation in street names.
Period allowed after first part of city

This is the original version of this RE I wrote
((\d{1,5}(1\/[234])?( [A-Z]([a-z])+)+)|(P\.O\. Box \d{1,5}))\r\n([A-Z]([a-z])+(\.?)( [A-Z]([a-z])+){0,2})\, (A[LKSZRAP]|C[AOT]|D[EC]|F[LM]|G[AU]|HI|I[ADLN]|K[SY]|LA|M[ADEHINOPST]|N[CDEHJMVY]|O[HKR]|P[ARW]|RI|S[CD]|T[NX]|UT|V[AIT]|W[AIVY]) (?!0{5})\d{5}(-\d{4})?$
But I couldn't add it the to library because the sample matches can't accept <CR> although the test expression box can
The only difference in this expression and the one submitted is the \r\n is replace by a space so sample cold be entered
One more note: a different RE parser would reject the input with \r\n but would accept \n or \s
This lib wouldn't match on \n or \s but would also take \s{2}
