Ah I see, we can maybe come up with something more specific that will avoid shorter codes… perhaps:
\b\d{3}[-.\s]\d{3}[-.\s]\d{4}\b
This will catch formats like 1-800-123-4567, 123 456 7890
If it’s more like +1 123 456 7890, this might work better to specifically catch the +1
\+1[-.\s]\d{3}[-.\s]\d{3}[-.\s]\d{4}
Neither of these will get false positives for shorter codes like 123-4567
