I think the original problem definition doesn't explain why it needs more than this - maybe you need some more test cases. You might find Expand <https://golang.org/pkg/regexp/#Regexp.Expand> / ExpandString or ReplaceAllStringFunc useful. Note that you can write your original regexp with capture groups to distinguish which branch matched: r := regexp.MustCompile(`(^9(\d{10})$)|(^00(.*)$)|(^\+(.*))`) ^ ^ ^ ^ ^ ^ $1 $2 $3 $4 $5 $6 Using ...Submatch or ...SubmatchIndex, you can identify which of the branches matched. If your regexp matches the first alternative, $1 (and $2) will be set. If it matches the second alternative, $3 (and $4) will be set.
