/[0-9]+[a-z]?(?:$|\b)/i I guess a regular expression should be suitable. The above is from my head and untested. [0-9]+ – matches any amount of numbers [a-z]? – optionally matches a letter (?:$|\b) – either matches the end of the string or a word boundary (space, dot, etc.) /i – search case insensitve
Should work for the examples you gave. You might want to limit the [a-z] to [a-l] because I haven't even heard of an "123 f", so it ignores some of the typos (i.e. 3r avenue). No idea how that works for languages other than English. The regex will find "5" as housenumber if someone e.g. writes "5. avenue".
